Beekeeping is practiced now a day on specific lines and honey extracted with art billing bees and gubs or destroying the comb. Bees are accommodated in artificial lives where they live comfortably with in easy reach of the bee keeper for examination and extraction of surplus lovely, after keeping of sufficient lovely in the combs for the bees. Honey is a part of bees, which gather sugar containing nectars from flowers. The main uses of honey are in cooking, baking, as a spread on breads and as an addition to various beverages such as tea and as a sweetener in commercial beverages. Honey is the main ingredient in the alcoholic beverages mead, which is also known as honey wine or honey bear. Honey is also used in medicines. The book contains the steps of bee keeping in proper manner and details of honey processing. This book is very useful for new entrepreneurs, technocrats and also for established enterprises.

History
of Beekeeping in India Present Status and Future
After independence, India launched a massive programme of rapid
industrilization with the belief that the benefits would percolate down
to the masses. Contrarily, only elites got benefited and rural people
continued to be poor resulting into movement of the unemployed to the
cities.
As 80
percent of the population lives in rural India and depend on
agriculture, it received more emphasis in the second phase of
development. Consequently huge investments were made in agricultural
research and extension and India became self-sufficient in food
production ranking World’s fourth largest grain producer. Special
efforts were also made to develop various agro-base industries like
dairy, poultry, fish farming, sericulture and beekeeping. Out of them
beekeeping industry received inadequate attention resulting in its
stagnation. Following paragraphs trace history and present status of
beekeeping in India followed by suggestions to rectify the current
state of affairs and give this industry a status it rightfully deserves.
History of Beekeeping in India
Although
honey and honey bees are known to human beings since time immemorial,
still beekeeping is not a Strictly traditional industry in India.
Efforts were made to introduce Apis mellifera, the European honeybees
in India since 1880. For various reasons these experiments did not meet
with success. It was around 1910 that Rev. Father Newton designed a
smaller hive, suitable for the Indian honeybee Apix cerana indica in
Kanyakumari and successfully maintained it in hives. Mahatma Gandhi
realised the importance of beekeeping industry and included it in his
rural development programme. Several freedom fighters were trained in
his Ashram at Wardha in the art of maintaining honeybee colonies. These
Freedom fighters from all over the country initiated beekeeping
industry in their respective States. Swami Shambhavananda from Coorg
District in Karnataka, Y.M.C.A., Martandom and Dr. Spencer Hatch from
Southern most coastal strip of India, Shri S.K. Kallapur and Shri S.G.
Shende from Western Peninsula, Shri R.N. Muttoo from Central Himalayas,
Smt. Rama Devi and Manmohan Chaudhary from orissa, Shri Rajdan from
Jammu and Kashmir did pioneering work in the establishment of modern
beekeeping in India. All these efforts, however, were restricted to
small pockets only. After independence, Government of India took a
policy decision to revive various traditional industries and an All
India Khadi and Village Industries Board was constituted to undertake
this work. The task of development of beekeeping industry was also
entrusted to this Board. This Board was later reconstituted as Khadi
and Village Industries Commission a statutory body of Ministry of
Industries. It was only after the establishment of KVIC at Central
level and Khadi and Village Industries Boards at State level that
beekeeping industry received serious attention for its development in a
coordinated manner throughout the country through well-knit
organisations like Village Industries Boards, Beekeepers’ Co-operative
Societies, registered public Institutions etc. In addition to this a
few states like Jammu and Kashmir, Himachal Pradesh. Karantaka and
Uttar Pradesh developed Departments of Beekeeping that functioned under
Ministry of Agriculture or Industries.
Beekeeping Extension
The (KVIC)
an Autonomous Statutory Body was established by an Act of Parliament in
1956 to plan, organize and implement the programmes for the development
of Khadi and Village Industries. Since beekeeping industry was included
in the schedule of KVIC, the Commission established Beekeeping
Directorate with adequate staff at its Headquarters in Bombay and
network of technical and extension staff in all states reaching through
Districts to potential villages. The organisation of Beekeeping
extension programme was as under:
Khadi and Village Industries Commission
The KVIC
had a Technical Staff of about 200 workers. The Beekeeping Directorate
had evolved about ten different patterns of assistance for providing
financial assistance to Beekeepers’ Co-operatives, Institutions and
individuals. Some of the patterns of assistance are (i) Establishment
of beekeeping sub-stations (ii) Model apiary-cum-nursery, (iii)
Migration of bee colonies, (iv) Construction of honey house (v)
Purchase of beekeeping equipment (vi) Training in beekeeping, etc.
Every year developmental plan for each state was finalised and
financial as also technical assistance was provided by the KVIC to
State Boards, Institutions, or Co-operatives for implementing the
approved programme.
State Khadi and Village Industries Board
What is
Khadi and V.I. Commission to Govt. of India is Khadi and V.I. Board to
State Government. The state Khadi and V.I. Boards receive financial and
technical assistance from Khadi & V.I. Commission for
implementing development programme. Each State Board has its own
beekeeping extension staff for implementing and supervising the
programme. The State Khadi and V.I. Boards implement the developmental
programme directly or through Co-operatives and registered
Institutions. At one time there were 600 Bee-fieldmen working on
contract basis on 600 Beekeeping substations all over the country.
Directly Aided Organisation
The
registered institutions or the Co-operative Societies established prior
to the establishment of the State Boards were taken on the list of
“directly aided institutions” by the KVIC. Kerala Sarvodaya Sangh,
Punjab Khadi Gramodyog Sangh, Bihar Khadi Gramodyog Sangh are some of
the very big organisations.
All India Beekeepers’ Association (AIBKA)
All India
Beekeepers’ Association was established in Nainital in 1937. Shri R.N.
Mutto Founder of the Association devoted his life for the development
of beekeeping industry in Uttar Pradesh. In the initial years, the
Association organised All India Beekeeping Conferences, which
popularised modern beekeeping and brought awareness about pure honey
extraction using centrifugal machine. The Association, as a directly
aided institution of KVIC took up beekeeping development programmes in
Uttar Pradesh. This Association has been publishing for the last 50
years a Journal entitled “Indian Bee Journal”. Besides publication of
journal other major activities of the Association are standardization
of beekeeping equipment, supply of beekeeping books, charts and other
audio-visual aids/literature.
Beekeeping Research
Bee
research in India, like beekeeping industry has a very recent history.
Its growth and development can be traced back to a little over four
decades as follows: -
Department of Agriculture and Colleges
Prior to
independence, most of the earlier research on honeybees was confined to
the entomology departments. The emphasis of this research work was
naturally on the academic aspects of Indian honeybees and provided very
valuable basic data.
Apicultural Research Laboratory, Mahableshwar (M.S.)
The Bombay
Village Industries Committee initiated beekeeping development programme
in Mahableshwar way back in 1948 under the leadership of Shri S.G.
Shende (now Chairman, All India Beekeepers’ Association). During this
extension programme Shri S.G. Shende associated Prof. G.B. Deodikar
with bee research programme realizing importance of source to sink. A
comprehensive programme of bee research was conceived which included
research on standardisation of beekeeping equipment, standardisation of
bee management practices, studies on bee-botany, bee genetics,
bee-pathology, chemistry and quality control of bee products etc. The
Apicultural Research Laboratory was thus established in Mahableshwar in
1952 formally inaugurated by Shri Morarji Desai, the then Chief
Minister of Bombay State.
It was
unique in the sense that it devoted to field-oriented research and
simultaneous attention was paid to different disciplines of bee science
like botany, management genetics and breeding, pathology and quality
control of bee-products etc.
Central Bee Research and Training Institute (KVIC)
The
Apicultural Research Laboratory, Mahableshwar undertook various
research projects of applied nature and published series of articles
thus attracted the attention of KVIC, which recognised this Laboratory
as All India Training Centre for beekeeping and also provided financial
assistance for the research programmes. The work of Laboratory however
was confined to limited area of Mahableshwar plateau and surrounding
valleys in Western Ghats. A need was then felt to expand the scope of
bee research activities to entire country. KVIC with the help of
Maharashtra State Khadi and Village Industries Board established
Central Bee Research and Training Institute (CBRTI) in Pune on 1st
November 1962.
The CBRTI
in turn established Regional Bee Research Laboratories. Field
observation Stations and experimental apiaries all over the country. It
undertook field-oriented research programmes under its Departments of
Botany, Melissopalynology, Bee-management, Bee-breeding,
Bee-pollination, Bee pathology and Bee-Chemistry. The work done on
different aspects was regularly published in national and international
journals. More than 100 scientific papers were published by the CBRTI.
It also prepared 10 to 15 drafts for secrutiny and adoption by Bureau
of Indian Standards. Gradually, CBRTI received national recognition by
organizations like Bureau of Indian Standards and AGMARK. The
University of Poona accepted it as a Centre for postgraduate studies on
bees and beekeeping. Similarly International Bee Research Association,
London and the Canadian International Development Agency, also sent
their recognitions. Members of the National Commission on Agriculture
(NCA) visited CBRTI and had series of meetings with the Scientists. The
NCA in its final report to the Government of India (1976) wrote one
Chapter on Apiculture and made many recommendations for the development
of beekeeping in India. One of the major recommendations was that CBRTI
should be developed as a primary national centre for honey and honeybee
research & training. It was further recommended that the
institute be treated at par with other Central Institutes of the ICAR
and the necessary funds and facilities should be placed at the disposal
of the institute.
The
Department of Science and Technology at the request of KVIC provided
funds for construction of building at Pune.
All India Co-ordinated Research Project on Honey Bee Research
and Training
The Ministry of Agriculture
accepted the report of the NCA and passed it on to Indian Council of
Agricultural Research for implementation. In light of the
recommendations of NCA and the needs of a vast country like ours with
climatic, floristic and phenological heterogeneity, a much larger and
co-ordinated programme was an obvious necessity. At CBRTI, in July
1981, broad areas of research and training were identified for
implementation at eight different co-operating Centres under All
India-Co-ordinated Research Project on Honeybee Research and Training
with main co-ordinating centre located at CBRTI, Pune. The Headquarter
of the Main Co-ordinating Centre remained at Pune for a couple of
years. Subsequently it was shifted to Haryana Agricultural University
Hissar. Other Co-operating Centres were located at Ludhiana (Punjab)
Vijayrai (AP) Jorhat (Assam), Pusa (Bihar) Vallyani (Kerala) Pantnagar
(UP) Solan (HP) Bhubaneswar (Orissa). Similarly one centre each at
Indian Agricultural research Institute (New Delhi) and the Chithali
station of Indian Institute of Hoticultural Research (Karnataka) was
established.
World
Scenario in Beekeeping
Beekeeping
is practised over a greater area of the earth’s surface than perhaps
any other single branch of agriculture and on it depends the success of
many other branches of agriculture. Honeybee originally belongs to the
old world-Europe. Africa and Asia and the bees spread to the new world
after 1638 in America, 1822 in Australia and 1842 to Newzealand. The
real boost to scientific beekeeping took place with the discovery of
moveable frame hive by Langstroth 1851. Later, sequence of events took
place by studying the biology of honeybees, development of beekeeping
methods, identification of different castes, queen mating, role of bees
in pollination etc. Although the beekeeping has since undergone
tremendous change both in equipment and management but the basic
principles have remained the same, as advocated by Langstroth and
Dadant and still form the basis of modern beekeeping. During the next
half century i.e. between 1850 to 1900, beekeeping exploded in the New
World.
Today most
of the countries practise beekeeping with the European honeybee Apis
mellifera which surpasses the Asian honeybee Apis cerana in almost all
the departments. This species has an unusually large distribution,
which encompasses widely different environments. A. mellifera is one of
the most successful species in the animal kingdom which has become
independent from environmental conditions to a great extent: one and
the same species is able to survive in semidesert tropical regions as
well as in cold temperate zones. Even countries like China and Japan,
which for a long time were practising beekeeping with Apis cerana, are
replacing the species with A. mellifera.
The Pattern of Beekeeping Today
We have now
seen that honeybees live in all the parts of the world, except polar
regions. However, the pattern of beekeeping in old and new worlds tends
to be different. In general, the new worlds tend to give richer honey
harvest, but the old world is densely populated with honeybees; as it
is with people. The new world provides more useful inventions for
handling bees and their products, whereas the old world still
contributes more fundamental discoveries about bees. Broad distinction
with exception is between the equipments used for beekeeping.
Beekeeping equipment used in the new world tends to be simple, uniform
and mechanism perhaps due to expensive labour. Mainly Langstroth and
Dadant hives are used. In European countries one man can look after 100
to 300 colonies. In Australia the figures are still higher, the most
mechanised beekeepers among all are in California where beekeeping
started around 1850 and a beekeeper can run 1000 or even 2000 hives
each.
In new
world, beekeeping is generally a means of livelihood and average honey
yield in most of the countries ranges from 10 to 20 kg/colony and the
average yield in best beekeeping district ranges from 100 kg to 150 kg
or even 200 kg. Contrary to this in the old world the beekeeping is a
hobby and sideline beekeepers are much higher, each owning 5, 10 or
upto 50 hives and getting a harvest of 5kg to 20 kg/hive.
In
good areas beekeeping is being adopted even without knowing great deal
about the bees themselves and beekeepers are neither much interested in
bees nor in beekeepers organisations. Contrary to this, in European
countries like Australia, Czechoslovakia, Germany, Netherlands and
Switzerland, where there is much awareness, with strongest beekeepers’
organisations, per hive honey production is low mainly because of
greatest density of hives. All these countries have more than 10
colonies per square mile and their honey yields are amongst the lowest
in Europe.
Race of Honeybees
The most
predominant species of hive honeybees in the world is Apis mellifera,
whose races can be divided into three:
1.
European races, 2. Oriental races and. 3. African races.
One can
determine some relationship between dark European bee and the North
African Tell bee and between Caucasians, Anatolian and Carniolan bees.
However, from point of view of economic value, there are four races of
Apis mellifera and they are:
1.
Dark
bees, A. mellifera mellifera L.
They are
spread throughout Europe, north and west of Alps and Central Russia.
But in the last decade they lost ground almost everywhere and presently
are confines to Spain, France, Poland and Russia. These are big bees
with short tongue, broad abdomen, dark chitin with small yellow spots,
nervous in temperament, good wintering, weak disposition in swarming,
and susceptible to diseases.
2.
Italian
bees, A. mellifera Ligustica Spin
Its
original homeland is Italy (exclusive of Sicily) and is somewhat
smaller than A. mellifera mellifera with slender abdomen. The bee is of
light colour with scutellum; hair have yellowish colour. These are very
clam bees, generally gentle, build exceptionally strong colonies with
high consumption of food. The good building instinct of this race has
been praised many times.
3.
Carniolans.
A mellifera carnica (Pollmann)
With
original homeland Austrian Alps, this bee is generally quite similar to
ligustica. Slender with long tongue, its chitin is overwhelmingly dark
with brown spots. Hair is grey. It is the quitest and the most gentle
race. Diseases of brood are virtually unknown.
4.
Caucasian,
A. mellifera caucasica Gorb
Original
homeland is Central Caucasus. In shape and size it resembles carnica.
Colour is dark with brown spots on abdomen. Hairs are grey-brown. It is
also gentle and calm. It raises strong colonies. Produces only weak
swarms cold hardy.
Besides
these important races. Apis mellifera adansoni has also been much
talked about these days. This north African bee is a very small, dark
in colour, highly aggressive in behaviour, high tendency to swarm and
migrating over long distances but excellent for honey production in
extreme climate of Africa.
In addition
to these races of Apis mellifera, we have the Asiatic hive bee Apis
cerana which closely resembles Apis mellifera in its body structure. It
is relatively cold hardy. It is genetically separated from A. mellifera
and attempted intermating produces lethal offspring. It does not
produce a strong colony and is, therefore, kept in smaller hive. It is
resistant to nosema disease. It produces relatively less honey and has
great swarming and absconding instinct.
There are
two other species of genus Apis in southern Asia, which are entirely
tropical. Both build only a single comb and nest in the open. Neither
of them can be kept in a hive although honey can be obtained from nests
of wild bees. These two species are, a dorsata and A. florea.
Honey Production
The total
honey production in the world is 1.1 million tones according to 1990
FAO estimates, out of which 66 per cent is produced by 10 major honey
producing countries of the world. In the foregoing account only the
major honey producing countries have been briefly described.
Beekeeping in Europe
About a
decade ago Europe (excluding USSR) had about 13 million colonies, with
an average 7-colonies/square mile, a hive density seven times as great
as in any other continents. The average honey yield was
l0kg/colony/year. It was low as compared to the new world as a whole.
Europe consumes more honey than it produces and Western Europe is the
world’s greatest honey importing region. In 1972, Europe imported
70,000 tons from New World of which 46,000 tons was imported by West
Germany. The honey production in Europe was 2,00,000 tones.
According
to the figures available for 1989 for European Economic Community
(EEC), the average yield per colony was minimum at Luxemburg (7.7
kg/colony) and maximum at Denmark (35 kg/colony) (Table - 1). Spain had
maximum number of bee colonies (1.6 million) and Luxemburg the least
(10,400). West Germany still Remains the world’s biggest importer of
honey which produced about 18,00 M. tons of honey in 1988 and imported
83,000 M. tons during the same period.
According to the 1984 estimate, the erstwhile USSR had 10 million
colonies, which had been built after World War II, the earlier stock
was mostly destroyed during the war. Its honey production was more than
one lac tons (average yield 11 kg/colony). The entire produce is
consumed in the country. Its beekeeping is on the pattern of Europe and
even the equipment is similar to that used in Europe. Most of the
beekeeping farms are run by the State, each of which maintains as many
as 6000 colonies. Since most of the activities are centrally governed,
there is virtually no conflict between beekeepers and plant
protectionists and all beekeeping and crop spraying activities are
systematically organised. The value of bees in fruit and seed
production is very well realised and growers and beekeepers work in
harmony. Efforts are a foot to become surplus in honey and wax
production. The USSR had traditionally exported small amount of honey
primarily to Eastern Europe. One of the constraints to Soviet export
was lack of high quality packaging material, which forced the USSR to
sell honey wholesale as opposed to the more profitable retail market.
Asia:
Till recently, Beekeeping in many Asian countries was a traditional
household activity. It is only recently that its importance has been
commercially realised in countries like China, India and Pakistan, as a
result of the introduction of high honey yielding species of Apis
mellifera. In other countries of this continent, there are small
beekeepers who keep one to five colonies of Apis cerana in different
traditional hives and produce honey by ‘squeezing method’. The total
honey production in Asia is only to the tune of about 2,50,000 M. tons.
China:
There are at present 8.5 million colonies in China out of which 7
million are kept in modern hives. Out of these 70 per cent are Apis
mellifera and others are Apis cerana. The annual honey production is
about 2,00,000 metric tons per year and total Royal Jelly and bee
pollen production is 1,800 and 1,000 tons per year, respectively. In
addition, bees wax and propolis are two other important hive products
that are harvested. About 30 to 40 per cent of hive products are
exported and rest are retained for domestic consumption. About 90 per
cent of honey and all the Royal Jelly is produced from Apis mellifera.
Royal Jelly is sold at a rate of US$100/kg. The Institute of Apiculture
Sciences of the Chinese Academy is mainly responsible for beekeeping
research and extension activities. There are more than 1,00,000
apiaries in China each having 30 to 80 hives. Beekeeping with Apis
cerana is practised in mountain areas. Each A. mellifera colony
produces from 0.3 to 0.5 kg of Royal jelly per year. Beekeeping got a
boost in China between 1949 to 1959 after the introduction of European
honey bee.
At present China is the world’s largest producer and exporter of honey.
Honey production in China is mainly a sideline activity engaged in by
crop farmers to enhance income but others specialise in honey
production. These producers move from region to region depending upon
season and local flowering conditions. They sell honey to total supply
and sale cooperatives’, which act as middlemen and re-sell honey to
retailers, food and beverage processors, producers of Chinese medicine
or in case of honey destined for export market to the ‘Native products
Import/Export Corporation (TUHSU)’.
India:
As per 1986 statistics (FAO) there are about 1 million bee colonies of
A. cerana and A. mellifera in India and annual honey production is
about 18,000 M tons. About half or more of this quantity is harvested
from wild colonies of A. dorsata and A. cerana. Beekeeping covers
4,00,000 villages providing part-time employment to 2,50,000 persons.
India has the potential of accommodating 5 million colonies and a
potential of producing 6,00,000 M tones of honey. Himachal Pradesh is
the only area in Southern Asia, which has announced support price for
honey.
Pakistan:
Our neighbour, Pakistan, produces about 640 M tones of honey of which
14 to 18 per cent comes from A. mellifera and A. cerana kept in modern
hives and the remaining from wild colonies of A. dorsata and A. cerana.
Nepal:
Its beekeeping is mainly with A. cerana and average yield is 5 to 6 kg,
although some beekeepers obtain as high as 25 kg/colony. It has mainly
traditional beekeeping. Other species such as A. dorsatal A. Laboriosa
and A. florea are erratic honey yielders.
Bangladesh:
Beekeeping is with A. cerana, A. dorsata and A. florea. A cerana yields
around 4 to 10 kg honey per colony. There are about 10,000 A. cerana
colonies kept in different types of hives by about 8,000 beekeepers.
Japan: In 1990,
Japan produced 4,300 M tons of honey fulfilled only 77 per cent of the
total annual consumption for a year. Japan is the second largest
importer of honey in the world. In 1990 Japan imported 69,435 M tons of
honey; China being the dominant supplier accounting for 86 per cent of
the honey for industrial use and only 35 per cent for table purpose.
In other
countries of Asia like Bhutan and Burma, beekeeping is virtually
non-existent and attempts are being made to boost beekeeping with A.
mellifera, however, it will take sometime.
Beekeeping
in India - Role of KVIC
Success of an Industry is measured by its achievement and the role of
Khadi & Village Industries Commission (KVIC) in the upliftment
of Beekeeping Industry is spectacularly well established.
Beekeeping
is an ideal agro-based subsidiary industry, providing supplementary
income to a target group of people from rural, hilly and tribal tracts
including horticulturists and agriculturists because of abundantly,
widely, and well distributed, bee flora. Apart from the direct benefits
of honey and bee wax, the indirect benefits through pollination etc.
are almost impossible to quantify which may simply outclass the direct
benefits.
KVIC
The KVIC is
a statutory body created by an Act of Parliament (No. 61 of 1956 and as
amended by Act No. 12 of 1987). It is charged with the planning,
promotion, organisation, and implementation of programme for the
development of Khadi and other Village Industries in the rural areas in
Co-ordination with other agencies engaged in rural development,
wherever necessary. The Village Industry means any industry located in
rural areas with a population not exceeding 10,000 which produces any
goods or renders any service with or without the use of power with the
fixed capital investment not exceeding Rs. 15,000/- per artisan or
worker.
Thus, the
beekeeping fitted perfectly in the perview of KVIC as it being the only
such organisation with a will to work and network in such areas.
Growth of Beekeeping under KVIC
Until 1953,
the beekeeping in Indian subcentinent was in a badly disorganised shape
until this activity was taken over by All India Khadi & Village
Industries Board and subsequently by the KVIC in 1957.
The KVIC is
responsible for taking Beekeeping Industry to the present height from a
mere 16,557 colonies to 13.44 Lakhs colonies and the honey production
consequently increasing from 0.21 Lakhs Kg. to 82.02 Lakhs Kg
respectively.
The liberal
financing by the KVIC coupled with the technical support in the form of
technical manpower, training, literature, supply of equipments,
followed by the marketing umbrella support to the beekeepers has led to
the present scale development of Beekeeping Industry.
Thus making
beekeeping in India and KVIC Synonymous.
Organizational set up of Beekeeping under KVIC
The
organisational set up is the key to effective planning and
implementation of beekeeping programmes.
Table
1
Growth of Beekeeping in different States/Areas
Being
entirely an agro-based industry, bee keeping is feasible only in areas
with adequate bee flora, atleast for a period of 6 to 8 months, with
one major honey flow season. Initially beekeeping activity was
concentrated in some southern states only. The KVIC is instrumental in
spreading it to entire India except the states of Gujarat and Rajasthan
where it is practiced at low key.
Table
2
The
southern states of Karnataka, Tamilnadu and Kerala contributed almost
40% of the total honey production till a fatal disease “Thai Sac Brood
Virus” (TSBV) damaged the whole of Beekeeping activity in these States.
Now the leading states are U.P., Bihar, Bengal, Punjab and Haryana.
In addition
to directly aided institutions, beekeeping programme is implemented
mainly through institutions, cooperatives, and individuals financed by
State Khadi & V.I. Board, which receives funds from KVIC.
Role of Central Bee Research & Training Institute
(CBRTI) Pune in research and technology development
While
implementing the bee keeping extension programme, the immense potential
of bees to reap unlimited floral wealth of India was realised which
resulted in the initiation of a KVIC sponsored comprehensive research
programme, relavant to Indian conditions, at Apicultural institute in
Mahabaleshwar (Maharashtra) in 1952.
Organizational set up under CBRTI, Pune
This set up
is unique in the sense that all the related aspects of the beekeeping
research are undertaken under one roof. In case of Indian Council of
Agricultural Research (ICAR), universities, colleges, institutions
etc., the emphasis on research is mainly devoted to Entomological and
pollination aspects whereas it is integrated on all aspects at CBRTI.
The
achievement of CBRTI in different divisions/departments are summarised
here.
1.
Apiculture
(a)
Development of Beekeeping Equipments:
It is an
important task and CBRTI has designed lots of equipments
(i)
Bee hives ISI (A-type, B-type and C-type)
(ii)
Bee hives stand (folding type and fixed type)
(iii) Honey

The
above-mentioned equipments have already been standardised by Bureau of
Indian Standards (formerly ISI). The following approved drafts awaiting
standardisation are:
(i)
Cylinderical bee packages
(ii) Honey
extractor tangential
(iii)
Beeman’s kit.
(b)
Role of RBRCs/FOS
The RBRC’s
and FOS’s with apiaries in different agroclimatic conditions were
established as per the recommendations of National Commission on
Agriculture (1979) to perfect management techniques in different
climatic conditions of India. The beauty of the idea is that after
every 5 years they move to virgin areas. This has led to phenomenal
recourse in managing different bee apiaries in different agroclimatic
zones of India.
Some of these techniques include:
(i)
Management of apiaries year round
(ii)
Supplementary feeding in dearth period
(iii)
Swarm control
(iv)
Management for higher yields
(v) Apis
mellifera management
(vi)
Migration both local and distant.
(c)
Introduction of exotic bees
The exotic
bee, Apis mellifera was initially introduced in Punjab, Jammu &
Kashmir on the individual level as well as by Agricultural University,
Ludhiana. After its successful introduction Apis mellifera bees was
popular and it was taken up in Punjab on commercial basis. The KVIC
after due experiments in the States of Bihar, U.P., M.P. and Punjab
approved introduction of A. mellifera in nothern States and approved
the pattern of assistance of Apis mellifera under its scheme of
beekeeping for the southern-northern States. The experiment is in
progress for introduction of A. mellifera in southern states.
2.
Entomology
Achievements
include identification, extent of damage and management of pests,
parasites and predators of bees including green bee-eater, wax moth,
mites etc. The control of the mites was achieved employing advanced
indigenously prepared strips impregnated with insecticides. The most
important work includes isolation; purification and identification of
mandiculat gland pheromone of different bee species different
insecticides with low LC 50 to bees were taken.
3.
Bee
Pathology
The section
made detailed studies on the isolation, fungal, identification,
etiology and management of different bacterial and viral diseases
including EFB, TSBV, etc. The hill variety of bees A.c. indica was
found to be relatively tolerant to the TSBV, which has played havoc on
beekeeping industry.
4.
Bee
Botany and Melletopalyonology
This department has collected
and classified more than 3000 plants species useful as bee plants. More
than 300 spices and plants have been given to forest/ agricultural
department. The polynarium with more than 4000 slides of pollen types
of India is unique which serves as a reference task to the scientists
from India and abroad. Analysis of pollen loads, pollen stores and
honey samples to identify its sources is another Analysis of pollen
loads, pollen stores and honey samples to identify its sources is
another facility created.
Beekeeping
Research Set-up, Achievements and Future Strategies
Honeybees
and honey find special mention in the Indian epics and bee hunting for
honey dates back to some 2000 to 2500 years. The innovation of movable
frame hive in the west in 1950’s ushered an era of revolution in the
field of Research in Beekeeping. Some attempts were also made in India
by the end of 19th century to keep bees in moveable frame hives but
nothing much was done till the recommendations of Royal Commission on
Agriculture in 1928. During 1930’s and 1940’s some beekeeping stations
were established in different parts of the country and some research
was initiated at places like Coimbatore, Pusa, Lyalpur and Nagrota
(H.P.).
After
independence, Village Industries Boards at state levels to promote
cottage industries including beekeeping, were established. For
co-ordination between the state boards, the national Government
established All India Khadi and Village Industries Board in 1953, which
later became autonomous Khadi and Village Industries Commission in 1956.
One
organisation set up after independence was Bombay village Industries
Committee which was later re-organised as the Village Industries Board
for earstwhile Bombay state and under its aegies appreciable beekeeping
extension work was done in Mahableshwar hills. A “Bee Research Centre”
was started at Mahableshwar in 1952 which was upgraded as Apiculture
Research Laboratory in 1954. Work done in this laboratory, especially
in survey of bee flora, palynology, cyto-genetics and honey analysis
etc. provided good base for KVIC to establish a Central Bee Research
& Training Institute at Pune in 1962. The CBRTI has been
implementing research programmes through regional Bee Research centres
and field observation stations. Some good popular articles and
bulletins were published and research findings emanated till early
1900’s when the Institute suffered set back in terms of technical
resource personnels.
Beekeeping
as a matter of stark fact should have been a part of agriculture but to
greater dismay the field remained neglected by the agricultural
Universities and Indian Council of Agricultural Research. It is only
recently that the beekeeping has come to be realised as an input of
agriculture. Entomologists working in some Universities/Institutes in
erstwhile Punjab Agril. University and later state Universities of
Punjab, Himachal Pradesh and Haryana have done some pioneering work in
some respects. All these efforts had been fragmented approaches for
resolution of research problems in apiculture. In 1980 a need was felt
by the ICAR for multilocational Research and All India co-ordinated
Project on Honeybee Research and Training (AICRP) was perceived,
enroping six Institutes/Organisations where co-ordinated Project on
Honeybee Research and Training (AICRP) was perceived, enroping six
Institutes/Organisations where co-ordinating centres were located.
Later on the umbrella of the AICRP was broadened by adding more
centres. The project now operates with co-ordinating centres in
important beekeeping states of the country. But these co-ordinating
centers are not provided with specialist scientists in each field of
honeybee research and even now the research efforts are little less
than systematic. Besides the co-ordinating centres of AICRP, there are
only few state Universities like H.P. University, Simla; H.P. Krishi
Vishva Vidyalaya, Palampur; Haryana Agril. University, Hisar;
University of Agricultural Sciences, Bangalore which have provided some
set up for honeybee research.
Research Achievements and Future Strategies
Beekeeping Industry and Honeybee Species
Growth and
development of beekeeping industry in India has not been satisfactory.
Honeybees in India are estimated to be availing about one fourth of the
floral resources available in the country. Thus there is enough scope
for expansion of beekeeping in potential areas. The average honey
production with Apis cerana indica is 5-10 kg per colony per year in
most areas and this production can go upto 25 kg in some very good
areas.
Three
species of true honeybees viz. A.c. indica, A. dorsata and A. florea
are indiginous to India and the fourth, A. mellifera (the exotic
species) is now established in the country and serving the commercial
beekeeping in many states. There is also likelihood of encountering the
other three recently described species of the genus Apis. A. dorsata
and A. florea are wild and honey hunters squeeze honey in forested
areas. Some efforts have been made to semi-domesticate and manage its
bee colonies. These bees offer some scope for management on commercial
lines.
Many
unsuccessful attempts were made by various workers to introduce and
establish A. mellifera in India since 1920’s. These attempts met with
failures, possibly because of lack of basic knowledge of apicultural
concepts and management skills. Successful introduction of A. mellifera
in India dates back to 1962-66 and the credit goes to the foresight of
Dr. A.S. Atwal. Two, three and twenty eight queens of the English
strain (developed by hybridising indigenous bees in U.K with Dutch and
Itallian bees), the Italian strain and californian strain were imported
from U.K., Italy and California (USA), respectively and one, two and
fifteen queens of the respective strains could be successfully
introduced in A. cerana indica young worker bees. The combs of A.C.
indica where gradually replaced by A. mellifera cell size foundations
and thus the colonies of the species were raised. Lateron 20 nuclei
(two lots of 10 each) were obtained from California in 1964 and 1965.
During 1966, 24 nuclei each of Starline (mid-west hybrid; mixture of
yellow and Caucasian blood) and Midnite strain (Caucasian hybrid) were
imported from Florida (USA). Initially the colonies of the exotic
species were maintained at Nagrota, Himachal Pradesh (then a part of
Punjab) and comparative performance of Indian bee and five
strains/hybrids of the exotic species were studied. This was also the
first successful example of inter-specific queen introduction. The
species has brought major revolution in honey production in some states
of India Dearth periods in subtropical regions are relatively short and
the bees that evolved there are poor honey gatherers. On the contrary,
bees of temperate region store large quantity of honey to survive
during extended dearth periods.
Therefore,
temperate zone honeybees are better suited for commercial honey
production for India. Average honey production with A. mellifera is
20-30 kg/year/ colony but through migration, beekeepers are getting the
high averages of 60-70 kg. Although, the beekeeping with introduced A.
mellifera is flourishing in some states, the species should be quickly
tested for its performance to spread to other potential regions with
greater research and extension support.
Bee Flora
Information
on different aspects of bee forage is essential for the efficient
management of honeybee colonies. Management scheme for each apicultural
region is closely correlated with the flowering of local honey and
pollen producing plants as also the climatic conditions. Basic research
in the area of forage ecology has been done and floral calendars for
different regions have been prepared. On the basis of surveys potential
beekeeping areas have been identified.
The most
serious problem for Indian beekeeping has been the decline in flora due
to deforestation and clearing of wastelands for extensive agriculture.
Improvement of bee flora is not possible by individuals’ efforts and a
beekeeper has to adopt and adjust only to the cropping patterns of the
area and forest wild flora available in the locality. Recently central
and state Governments and local organisations have helped in expansion
of planted areas of bee forage along highways, wastelands etc.
To get good
results, plantation of selective trees and shrubs is essential and this
should be done on the basis of multiple use principle including bee
forage as one of the uses. Flowers of many plant species are visited by
bees for nectar and or pollen but relative importance depends on the
quality and quantity of rewards available and also on the density of
the plant species. Intensive research in this area has generated this
type of information on many of the important flora. The knowledge
accumulated can be made use of while planning plantations on the basis
of accessibility of the potential bee forage areas and migration
schedules can be worked out. Migratory beekeeping is practised by many
commercial beekeepers in states like Himachal Pradesh, Bihar and south
India but micro-regional survey of bee forage would be required for
planning short and long distance migration schedules.
Equipment and Management
Efficient
management requires the use of appropriate equipment and operations
concerning the well-being of bees. Many types of hives had been in use
in India and attention of the scientists was attracted to standardise
the hives and with these efforts the ISI (BIS) hive specifications laid
down on the basis of body size (bee space). Increase in brood and super
chamber capacities has been suggested keeping in view the colony build
up capacity and length of build up and honey flow reasons. BIS have
also formulated standards for other bee equipments.
Knowledge
of biometry of bees is helpful in standardising bee equipment, for
breeding work, and for gathering information on the races of a species.
Good information on body size, tongue length and other morphometric
characters is available for A.c. indica. Egg laying capacity of queens
and consequently colony build up capacity varies from south to north of
the country. Therefore, exhaustive studies are required for all the
regions, to develop suitable queen excluders, comb foundation mills,
bee escape, honey extractors, pollen traps etc. For A. mellifera only
standard Langstroth hive is being used everywhere in India whereso-ever
the species is present. In these and other areas need might arise to
make suitable amends in sizes and number of frames etc. to suit
different zones. Timber is becoming expensive and cost of hives is
increasing. To keep the investment in beekeeping low some alternative
materials like polurethene, polystyrene and compressed sheets etc.
shall have to be tried.
Many other
practices for better management of honeybee colonies have been worked
out and standardized. Mass queen rearing for colony multiplication is a
very useful practice. The queens (30-40) reared in one queenless or
queen right colony can be given to new divides just before the
emergence. This saves the wastage of many days for queen rearing by
each divide. Time and length of divides in regions have also been
worked out. Oversummering is a problem in many parts of our country
because bees are troubled by high temperature and it is also no flora
period. Methods have been recommended for successful summer management,
which also includes feeding of pollen supplements, and substitutes to
make colonies to continue rearing some brood.
India
presents a variety of ecological conditions from north to south and
east to west. To some extent the art of beekeeping can be uniformly
adopted but some management problems, specific to different regions,
are needed to be tackled on priority. Similarly, summer and rainy
season dearth periods need immediate attention. Other problems that
should attract the attention of bee scientists are strength of divides
for colony multiplication etc. Little work has been done on the problem
of swarming and absconding in A. cerana indica. In addition work on
behavioural aspects of Apis spp. is needed to evolve the management
calendar for bee apiaries. Limited information is available in India on
communication behaviour, foraging distance and nectar and pollen
carrying capacity. Exhaustive information on these aspects is needed to
standardise management practices for different ecological regions for
efficient management of hive bees.
Genetics and Breeding
Information
on genetics and reproductive biology is required for planned bee
breeding and stock improvement programmes. It was hypothesised by Dr.
Deodikar and co-workers that during the course of its trans-Himalayan
migration, the primitive tetraploid Indian honey bee might have
gradually differentiated into an advanced tetraploid Apis mellifera.
All along these migratory routes, Apis mellifera differentiated further
into a number of African, European and Sino-Japanes races. Cytogenetic
studies of Apis spp. have shown that A. cerana indica has the same
number of chromosomes as the European bee. The male has 16 chromosomes,
which occur in 8 homomorphic pairs showing pronounced somatic
association, it was inferred that the males though numerically haploid,
may be closely approaching diploid condition genetically. The females
show a close approximation to a tetraploid condition. This inference
has been corroborated by chromosomes in A. Florea and A. dorsata which
have 16 chromosomes in female and 8 in the male. Reproductive biology
is also worked out in Indian honeybee. The queens of the species can be
inseminated with instrument but difficulties like production of low
quality semen; its separation from mucous and lesser concentration and
activity of spermatozoa are encountered. Experiments on hybridization
between two hive species have not proved successful. Intensive research
in needed in reproductive biology and genetics of Indian honeybee and
breeding of Apis spp. The present day A. mellifera stock has descended
from varied and heterogeneous blood, therefore, we have to talk about
inbreeding depression with caution and verifying the facts. We will
have to be over cautious in importing more A. mellifera bees since it
will run the risk of introducing diseases and enemies. Artifical queen
bee insemination techniques has been standardised/ practised in our
country, therefore safest alternative would be to import semen and use
for hybridisation as and when the need arises.
Major
Constraints in Beekeeping
BEEKEEPING WITH APIS CERENA INDICA AND APIS MELLIFERA
The KVIC
since 1952 promotes A.c indica, the Asian honey bee. The number of
colonies of this bee in India is about 0.96 million, yielding 6300
metric tonnes of honey with an average yield of 6.7 kg per hive.
Various
Agricultural Universities of (Punjab, Haryana and Himachal Pradesh) for
the last three decades promoted Apis mellifera, the Italian honeybee.
The colony number of which is about 0.1 million with a total honey
production of 13,700 tonnes, with an average yield of 13.7 kg per hive.
Compare
this data to that of China which took up commercial beekeeping with A.
mellifera around 30 years ago and now has 6 million bee colonies
yielding 180,000 metric tonnes of honey and is the worlds largest
exporter.
Obviously,
there is something wrong with the impetus, direction and assistance
given to beekeeping in India. This paper, therefore, attempts to define
the constraints in this regard and suggest suitable measures for
overcoming them.
THE MAJOR CONSTRAINTS FOR THE DEVELOPMENT OF BEEKEEPING IN
INDIA ARE AS FOLLOWS
1.
Using the Correct Species for Beekeeping
All
over the world, the Italian honeybee is acclaimed to be the choice for
commercial beekeeping. However, the controversy regarding the
suitability of the species i.e. Asian honeybee, A.c. indica and the
European bee A. mellifera for beekeeping in India, which has been going
on for the last three decades, gave a severe set back. Thank God this
has now been resolved and the two species have been accepted to be
complementary to each other. Even then if we are to put India on the
world honey map we must decide to use A. mellifera for commercial
beekeeping all over India.
2.
Availability of Genetically Superior Queens for Increased
Honey Production
America has
developed hybrids of high yielding queens of A. mellifera, Australia
has a programme in New South Wales for developing superior queens of
this species, U.K. has the Buckfast bee developed by brother Adams. In
India research programme needs to be oriented in this direction so that
desired results may be obtained and we may increase the yield per
colony to the desired level.
Queen
breeding is a long, and tedious developmental process. During our last
17 years experience of breeding, A. mellifera at our own apiary, we
have managed to do line selection of queens giving upto 80 kg of honey
per hive, but because of the unavailability of queen insemination
equipment, we have not been able to standardize the genetic stock. Even
though our queens are raised by grafting, yet they mate in the air and
drone population cannot be controlled entirely in the vicinity of the
mating yards.
It is
imperative that queen breeding by grafting and artificial insemination
be taken up intensively to improve the genetic stock and develop line
breeding and hybridization of both the species.
It is
essential to give grants to private breeders and governmental breeding
institutes to enable them to set up the requisite infrastructure for
the production of large volumes of genetically superior queens for
supply to the beekeepers.
3.
Lack of Technical Knowledge for Efficient Management of
Colonies for High Honey Yields
This is a
major constraint. Beekeepers are not aware of international methods of
efficient management. Some of the wrong practices followed by
beekeepers are: -
(a) Few
beekeepers use queen excluders, Further the excluders that are locally
available get rusted and damage the bees.
(b) We
have heard of outdated concepts like queen gates being recommended for
bee colonies to prevent bees from absconding.
(c)
Efficient swarm control is not practiced by beekeepers and
they are most unaware of these techniques. Most beekeepers just divide
colonies to prevent swarming.
(d)
Although maximum yields from A. mellifera are obtained
when the colonies go upto 3 to 4 chambers with populations of 50,000 to
70,000 bees yet few colonies with beekeepers are raised to that level.
(e)
Beekeepers do not know the concept of the food chamber as
a measure of colony build up and mostly maintain colonies on a single
chamber leading to weak colonies that die in dearth periods.
(f)
Few beekeepers change queens every season before the honey
flow leading to loss of queens during the crucial honey flow.
(g) Some
beekeepers even do not use full comb foundation sheets and only use
strips of wax sheets for the frames which leads to excessive drone comb
construction besides wasting the time and effort of bees in making
extra comb. Therefore, there is a great scope for improvement.
4.
Lack of Infrastructure at the Grass Roots and National Level
for Beekeeping
This
is the major cause for the use of wrong management practices by
beekeepers and needs to be urgently attended to for the success of
beekeeping in India.
(a)
Our agricultural universities do not have departments of Apiculture but
only departments of Entomology where bees are just one of the insects
in the department. Beekeeping has to be given the same status as
poultry and dairying in our institutes and then only can we turn out
beekeeping specialists from the universities who specialize in bee
management, breeding, disease control, quality control and so on. At
the moment the universities only turn out entomologists who have
knowledge of beekeeping and who in any case are too few to be able to
have any impact in the field.
(b)
There is no concept of beekeeping inspectors, or trainers in beekeeping
at the village or even district level.
(c)
Beekeeping, by its nature, has seasonal crises of disease, management
and so on. It is not sufficient to have a few people in universities
for advise on beekeeping. The only way that China managed to take up
beekeeping so fast and so successfully was the availability of trained
field workers in beekeeping at the village level. We must therefore
have a hierarchy of beekeeping experts and trainers in the villages,
blocks, Tehsils, Districts and then finally in the universities to be
able to have effective feed back to and from the beekeepers.
(d)
There are no organized forums for the meeting and discussions amongst
beekeepers, which are essential and are available all over the world.
In India beekeepers work in isolation and hence loose the benefits of
interaction with others in the field. Whereas we have found during our
visits and interactions with beekeepers in Europe, Australia etc. that
there is free flow of beekeeping information and knowledge amongst
beekeepers in those countries. In the field of beekeeping all over the
world, new techniques and improved methods of beekeeping have
essentially been developed in the field by this interaction amongst
beekeepers and then scientists in the field.
It is thus
essential to improve our infrastructure and communication for the
success of beekeeping in India.
5.
Poor Quality Control for the Production of Honey
This is a
very important aspect of beekeeping and needs to be stressed on if we
are to progress. It is not enough to produce large amounts of honey but
that is more essential to produce quality honey. It is because of this
reason which most Indian honeys do not come up to international quality
standards. The beekeeper should therefore be quality conscious.
(a)
Some beekeepers extract honey from brood frames which process damages
the brood and the honey extracted is of poor quality.
(b)
All beekeepers do not maintain separate super chambers for the
production of honey. The honey is produced in old brood frames and so
gets darker in colour and also is not so clean as if extracted from
only super frames. Dark honeys fetch very low prices internationally.
(c)
Since many beekeepers do not use queen excluders, the queen lays eggs
in the honey chamber thereby lower the honey quality.
(d)
Many beekeepers do not wait for the honey to be properly sealed before
extracting. Honey only develops the flavour, which is particular to
each flower source if it is allowed to stay in the hive a little more
after the bees seal the frames. Most beekeepers extract the honey while
it is still fresh and not entirely sealed. This leads to high moisture
content and low quality.
(e)
Beekeepers do not use the technique of keeping supers in warm rooms
with a forced airflow before extraction. This produces honey with
excess moisture. In the absence of desired warm extraction, it cannot
be sufficiently clear and so requires further heating before
filtration, which causes deterioration of quality. Honey from warm
supers can be easily extracted and cleaned straight away by simple
filtration through muslin.
In case
unripe honey is extracted, it is high in moisture content and lacking
in colour, flavour and quality. In order to be able to market our
honey, we must improve its quality.
Honey is
also poorly stored by beekeepers in old tins, which rust and so darken
the honey further. Besides, the honey in contact with the old tin plate
becomes blackish in colour and loses flavour, the tins being produced
now are mainly for oils and ghee and do not have sufficient tin plating
to be able to store honey cleanly. Lacquered tins are expensive and so
beekeepers do not use them for storing honey. Food grade plastic
containers need to be developed for storing honey.
6.
Emphasis on Production of Honey Instead of other Bee Products
At the
moment only honey is produced by the beekeepers. Honey bee can also
produce pollen, propolis, royal jelly, beeswax, bee venom which can add
to the overall income from the bee live.
(a)
Bees
Wax
This is
easily produced, has great demand in the world market and is used in
the cosmetic and pharmaceutical industries. The most important producer
of beeswax in India is Apis dorsata. This is not so pure as the beeswax
obtained from Apis mellifera, which has a greater export demand.
However to produce beeswax from the bee colonies, supers must have only
7 to 8 frames instead of 9 frames so that beekeepers can produce larger
quantities of beeswax from the bees.
(b)
Pollen
Pollen is
not produced at all in India. Pollen is a natural vegetarian protein
source containing many nutritive elements and minerals and can do much
to improve the general nutritional intake in rural areas. It also has a
great demand in the export market.
There is
tremendous potential for pollen production by the bees, particularly
from coconut, the mustard species of oilseeds, maize, sunflower etc.
Pollen is easy to produce and beekeepers can use simple technology to
supplement the income from the hive by inducing bees to collect pollen.
Pollen can be produced in tons.
(c)
Propolis
Propolis is
the resinous substance collected by bees from trees to seal cracks in
the hive. Propolis has been found to be a natural antibiotic and has
many medicinal qualities when used externally or internally and is
valuable in the field of Apitherapy. There is great demand for propolis
for export.
Propolis
collection is by the use of special propolis screens and can be easily
mastered by the average beekeeper.
A.c.
indica does not collect propolis and there is great scope for the use
of a mellifera for propolis collection.
(d)
Bee
venom
This is an
unexploited source of production from the bees in India; Bee venom has
various medicinal uses in Homeopathy, Allopathy and systems of natural
medicine. Extraction is complicated and can be done by beekeepers with
great technical skill using special bee venom extractors in front of
the hive.
(e)
Royal
Jelly
This is
secreted by the bees from special glands in their body and is used to
feed the queen bee larva. It is supposed to have rejuvenant and
beneficial properties, like Ginseng. It contains various natural
hormones and is a highly concentrated food. It has a great demand for
exports. China has become a major producer and exporter of royal jelly.
Royal jelly however, can only be produced by beekeepers having high
technical knowledge.
All the
above by-products from bees are not produced yet in India and can add
to the income of beekeepers, besides having great scope for exports.
7.
Disease
Prevention, Control and Analysis
This is the
major constraint for the development of beekeeping in India. We need to
have regional and also central bee disease analysis laboratories. At
the moment this is lacking and as has been seen in the recent outbreak
of sac brood in the South, the beekeepers could not get timely help or
advice regarding the disease that was killing their bees.
(a)
We do not have disease control inspectors to visit the beekeepers all
over India. These inspectors need to have detailed training in being
able to identify all the bee diseases and also take samples from
apiaries to have them tested.
(b)
There is no method of registration of apiaries and beekeepers all over
India. In America disease inspectors are there in each state who
register apiaries and take regular samples to declare them disease free.
(c)
Breeding apiaries must be registered as such and only those whose
colonies are free of disease should be allowed to sell queens and bees
all over India. This is followed in America where breeders get their
bee colonies certified disease free before supplying queens to other
beekeepers.
(d)
There is no control on the movement of bee colonies all over India.
Only colonies free from bee diseases should be allowed to be moved all
over for migratory beekeeping. This requires us to set up the
infrastructure for sampling and analysis of bee colonies from each
apiary.
(e)
Beekeepers use poor management techniques like continued use of old
frames and extracting honey from brood chambers. Weak colonies are
allowed to survive and have the danger of absconding and spreading
disease. Honey is a carrier of brood diseases of honeybees and the
practice of extracting honey from brood chambers is dangerous as brood
can die when the honey is extracted and the dead brood in the frame is
a source for the development of disease.
(f)
Beekeepers do not use good management practices of keeping their
colonies clean and so the danger of disease is even more. Beekeepers
need to be educated regarding these procedures.
As can be
seen there is much to be done for disease analysis, prevention and
control at the National and regional level.
8.
Lack
of Sufficient Financial Help from Government and Lending Institutions
for the Development of Beekeeping
(a)
Beekeeping requires long-term loans at easy rates of interest. That is
the procedure used by China to take up beekeeping in a big way. The bee
colony produces honey only after almost a year initially and then
seasonally. Beekeepers need help to be able to get finance for bee
colonies and equipment.
(b)
Insurance of bee colonies needs to be done at a reasonable premium so
that beekeepers can recover their losses in case of disease or the loss
of bees due to other factors.
9.
No
Tax or other Monetary Benefits for Beekeeping
(a)
Beekeeping is neither considered an industry nor an agricultural
activity and there is no tax benefit on beekeeping income. Beekeeping
is a long-term developmental activity and requires to be given tax
incentives for people to take it up in a big way. China gave the
beekeepers many incentives for them to take up beekeeping and so had a
quick growth in this field.
(b)
Beekeeping is also a high-risk activity and is dependent on the
vagaries of the weather for production. Many times, even though
flowering crops are available, nectar secretion is low because of
climatic factors like moisture in the soil. Some times rain at the time
of flowering causes the bees to collect little honey. The bee keeper
has to be given financial support during seasons of bad honey harvest
to sustain his colonies for the next season.
10.
No
Control on the Use of Pesticides by Farmers Leading to Death of Bee
Colonies in Field Locations
The
indiscriminate use of pesticides leads to the destruction of bee
colonies in the field
(a) There
is no legislation restricting the farmer from the use of pesticides
that are harmful to bee colonies. In many countries farmers are
required to inform beekeepers in their area as to when they may be
spraying pesticides on their crops. India has no such system and bee
colonies perish by the farmers using pesticides harmful to bees.
(b) Only
pesticides that are not harmful to bees should be used and should be
propagated with farmers. Bees are very important pollinators and
destroying them is a national loss as well.
11.
Pricing
Structures for Honey
There is a lot of lobbying by
farmers, beekeepers and beekeeping societies to give the beekeeper high
prices for honey. Himachal had fixed a support price for honey at Rs.
30 per kg. This has resulted in large stocks of honey lying unsold as
beekeepers refuse to accept lower prices for their honey. International
prices are around Rs. 20 per kg for the most superior quality honey. If
Australia can meet that basic price with their high basic costs as
compared to India, why should Indian beekeepers expect more for their
honey here which in any case is not even up to world quality standards?
To get more income from honey, yields should be increased and not
prices.
Morphology,
Anatomy, Colony Organization and Life Cycle
The
honeybee belongs to family Apidae of order Hymenoptera. It shares the
general characters of class Insecta. But the organ systems are
variously modified to lead a specific life that is food habits, social
life and other ways of life. A brief account of different organs and
the way they have been modified to perform a particular function, as
essential for understanding the activities of bees, is given below.
Morphology
Head. The
head of adult bee bears a pair of geniculate antennae. The third
portion (flagellum) has many sensory structures, which are mainly
chemo- and mechano-receptors. The compound eyes are placed on the
lateral sides of the head. Bees can distinguish colour but are red
blind. They can perceive ultraviolet rays but cannot perceive the red
light spectrum that is beyond 620 m wavelength. Bees can also see
polarized light. It is well known that bees communicate the food
sources with reference to the position of the sun but even in cloudy
days or when the sun is obscure the bees perform communication dance
with reference to the position of the sun and this is done by receiving
polarized light. In the top portion of head capsule the bee has three
ocelli. The ocelli perceive only the degree of light and do not form an
image on the retina.
Two
mandibles are attached to ventro-lateral part of the head capsule. The
mandibles differ in the three castes of honeybee (Fig. 1). In workers
the mandibles are narrower in the middle and broader at the base and at
distal end. Each mandible has a channel, both sides of which have
fringed hairs. This channel leads to a groove, which ends at the
opening of mandibular gland. The mandibles are used for grasping,
scraping pollen from anthers, feeding pollen, and manipulating wax
during comb building. Mandibles of the queen differ from those of
workers in that they have bilobed distal end and there is no groove
from the mandibular gland opening. Mandibles of drone are smaller in
size and have faint groove, covered with long hairs, with an apical
projection.
Fig.
1. Head capsules and mandibles of castes of honeybees.
The
mouthparts in worker bees are modified for sucking and lapping. The
proboscis or tongue, which is used for ingesting liquids, is formed by
median labium and two lateral maxillae. Labium has long glossae. At the
time of sucking food, galeae of maxillae and labial palpi form the
anterior and posterior coverings and are appressed together with
paraglossae forming the axial part of the food tube. The two
paraglossae are united together. The tongue has a deep grove with a
partition made by a rod, which is curved backwards. One canal serves as
salivary canal through which the saliva is ejected on the food before
feeding and the food is ingested through the second canal. The tongue
has a spoon shaped lobe at the end. With the lapping motion of the
tongue the liquid food is drawn into the food canal of the proboscis
and the food channel leads to mouth cavity. The preoral cibarium and
postoral pharynx form sucking pump. With the help of sucking pump the
food is forced into the oesophagous and honey stomach.
Worker bees
feed the young larvae and the queen with the glandular food called
‘royal jelly’. The food is secreted by hypopharyngeal glands, which are
long coiled strings of small lobes and are present in the head region.
The brood food appears at the base of the open mandibles of the nurse
bees.
Thorax. As
is common with other insects the second body region, thorax, consists
of three segments and is joined to the third region, abdomen, by a
narrow propodeum. Thorax carries the organs of locomotion, the legs and
wings. The leg of honeybee is composed of basal coxa, femur, long
tibia, tarsus and pretarsus. Tarsus is subdivided into tarsomeres and
small pretarsus bears the claw. Besides locomotion the legs in
honeybees are also modified to perform other functions. Prothoracic
legs serve as antenna cleaner. The basal part of the basitarsus has a
notch and small lobe projects from the distal end of tibia. The notch
has two rows of spines. The flagellum of the antenna is placed on the
notch and the tarsus is flaxed against tibia. The antenna is drawn
upward and is thus cleaned in between the notch and the projecting
clasp. The modification is met with in all the three castes of
honeybees. Hind legs in worker bees are modified for pollen and
propolis collection. The tibia has double row of curved hairs, the
space enclosed in between these is called corbicula or pollen basket.
Adjacent margins of tibia and tarsus have notch. Notch on the tibial
margin has a row of stiff spines and the opposite trasal margin is
modified into a lip called auricle which is also fringed with hairs.
Hairy brushes on the tarsi of fore and middle legs collect pollen
sticking to head and thorax regions, respectively. The pollen from fore
leg is transferred to middle leg of the respective side. The spines on
the tibial end of the hind leg brushes the pollen from opposite leg.
The pollen falls on flat surface of auricle. By the upward movement of
tarsus the pollen on the auricle is pressed against the outer surface
of the tibia and thus a pollen load is accumulated.
Fig.
2. Mouth parts of worker bee.
Abdomen.
The abdomen in adult worker and queen appears to be six segmented,
segments 8 to 10 are reduced in size whereas first is transferred to
thorax during pupal stage. The abdomen bears sting, wax and scent
glands and genitals and also contains the principal viscera inside.
Fig.
3. Hind leg of worker bee.
Sting. In
worker bee the egg-laying apparatus (ovipositor) is modified into a
sting. Sting is formed by three long stylets attached to the bulb. The
ends of the stylets have two lancets, which are hollow, and when in
contact with each other, they form a poison canal. The bulb at the base
of shaft made by lencets is supplied by poison sac, which is the
reservoir of poison gland. Venom is injected into the body of the
victim with each movement of the stylet. These movements continue even
after the sting has been inserted. The lancets have curved barbs and
the sting apparatus is broken off from the bee’s body in the attempt to
pull it out. Queen has well developed poison glands with large poison
sac but the lancets lack the curved barbs and she uses it for stinging
the rival queens.
Wax glands.
Wax glands are situated in the sternites of 4 to 7 abdominal segments.
These are polished plates (mirrors) and formed by the modification of
epidermis. The wax glands become active in the worker bee at the age of
14 to 18 days. Wax is secreted in liquid form, which solidifies into
thin flakes.
Scent
glands. The scent glands are present in the thin membrane connecting
the last two abdominal terga. The Bee bends her abdomen and exposes the
membrane to produce the scent. The odour produced by the cells is
derived from scented waste products of metabolism.
Anatomy
The
first part of the digestive tract consists of mouth, pharynx and
oesophagus with expanded honey stomach. Following the honey stomach
(sac) is a valve, which regulates passage of food into ventriculus. The
valve can remove the pollen from nectar and by the action of this valve
nectar can be retained in honey sac while the pollen passes to the
ventriculus. Digestive enzymes are released by the epithelial lining of
the stomach. Digested sugars are absorbed into the blood through the
walls of the ventriculus. Digested proteins (amino acids) are absorbed
in the small intestine. The small intestine leads to rectum, which
holds the faeces until it is discharged during flight.
Honeybee
has open circulatory system formed by the heart and the aorta. The
blood is pumped from the five-chambered heart into the aorta. The
chambers of the heart have ostial valves which allow the blood to enter
into the heart but backward movement to body cavity is prevented. The
blood is poured into the body cavity below the brain at the anterior
opening of aorta. The organ systems freely bathe in the blood in the
body cavity. The muscle movement of dorsal diaphragm helps in pumping
the blood, whereas ventral diaphragm beats in backward direction.
Respiration
takes place through spiracles present on lateral sides of various
segments of the body. Spiracular openings are attached to tracheae,
which ramify into trancheoles. The tracheae and tracheoles supply
oxygen to respective segments of the body.
Excretory
system is of generalized type. Many thin tubes called Malpighian
tubules; extend in the body cavity around various organs. They collect
waste metabolites from the blood present in the body cavity.
Brain and
ventral nerve cord constitute the central nervous system. Brain has
three distinct parts; the anterior most having optic lobes, antennal
lobes and mushroom bodies. Mushroom bodies are the centres of instinct
and memory co-ordination. Ventral nerve cord has seven nerve centres
(ganglia). These centres innervate the various body regions. Sensory
nerves extend from the receptive cells of the sense organ to central
nervous system. Eyes are the important sense organs. On the body of the
bee, there are innervated hairs, which perceive the mechanical
stimulus. Small thin-walled peg-like hairs can perceive odour.
Female
reproductive system is fully developed in queen but in workers the
system is greatly reduced. Two large ovaries have a number of egg
tubules or overioles, which lead to lateral oviducts. The two lateral
oviducts join posteriorily to form median oviduct, which leads to
vagina. Spermatheca is a pouch like structure and serves as storehouse
for sperms. The spermatheca is connected to vagina by a spermathecal
duct. Tongue like valve fold closes the opening of median oviduct when
the sperms are pushed into the spermatheca. Bursa copulatrix
accomodates penis at the time of copulation. The valve fold when
raised, makes the micropyle of the egg to come in contact with the
sperm released from the spermatheca and the fertilization takes place.
The ovipositor which is modified into a sting helps in depositing the
egg. Soon after mating, the sperms migrate from the vagina to the
spermatheca, which stores about five million spermatozoa. These
spermatozoa remain viable, get nourishment during storage and are
released in small numbers for the fertilization of the eggs. Male
reproductive system has paired testes with one vasa deferentia each.
Both the vasa defrentia join posteriorly and form an ejaculatory duct,
which leads to penis. Two mucous glands unite with ejaculatory duct. On
an average each drone produces 1 mm3 semen in A. mellifera and 0.16 mm3
in A. cerana indica.
Fig.
4. Reproductive organs of drone, worker and queen.
Colony organization
Honeybees
are social insects and live in colonies with a highly organized system
of division of labour. There are three castes: queen, workers and
drones. In a normal colony there is one queen, 10,000 to 30,000 workers
and a few hundred drones. In A. mellifera colony the number of workers
before honey flow may go to 60,000-70,000.
Queen.
The queen is the only perfectly developed female and is the mother of
the colony. In the peak of the season, she may lay large number of eggs
in a day, weight of which is almost twice the weight of her body.
She mates
with the drones, the male bee, in the air only once in her lifetime.
The stock of male sperms received during mating is preserved in a
pouch-like structure, spermatheca, in her body. She draws upon it for a
long time (which may be two or three years) to regulate the sex of the
offsprings. She can lay fertilized or unfertilized eggs at her will.
From the former, workers and sexual females or potential queens and
from the latter drones are produced. The differentiation in the workers
and the queen is not due to the quality, as previously believed, but to
the quantity of the food fed to the larvae. The partial stravation,
from about the third day, of the female larvae that are reared in
worker cells, results in their differential growth and they become
workers instead of queens, which they would have become if they would
have been lodged in the larger queen cells and had constant access to
more food. The queen in her rounds over the combs lays eggs in the
worker, queen or drone cells. The eggs are generally laid in concentric
circles. As the old queen shows signs of decline in laying fertilized
eggs or if a colony is under swarming, supersedural or emergency
impulse, new queens are reared in specially prepared queen cells. On
emergence a new queen roams about on the combs, feeds herself on honey
and takes one or more orientation flights out of the hive after 5 to 10
days of emergence. On her mating flights she is followed by drones and
have multiple matings in one or more days. Her mate dies during the act
of copulation and falls on the ground. The queen returns to the hive
with the mating sign, the male reproductive organ attached to her
reproductive opening, which is removed by the worker bees. After 2 to 4
days she starts laying eggs, first slowly then vigorously. The number
of eggs laid depend upon the amount and kind of food she receives from
the workers and the availability of other favourable conditions for egg
laying and brood rearing.
The queen
is heavily worked individual and quickly transforms the food, given to
her by the workers, into eggs. She, however, lacks the motherly
instinct and the function of nursing the young ones is performed by the
worker bees. An A. mellifera queen lays up to 1,800 eggs per day during
active brood-rearing season but A. cerana indica queen lays from 500 to
1,000 eggs per day. Number of eggs laid by queen of Indian bees in
Kashmir is comparable to A. mellifera. Egg-laying rate diminishes with
the age and in failing queens.
Worker. The
worker bees are imperfectly developed females. Unable to reproduce, but
possess all the maternal instincts. They are responsible for the
maintenance and welfare of the colony. Division of labour in worker
bees is on a physiological basis, which is explained elsewhere in this
book.
A worker
bee has no individual existence and throughout her life she labours for
the good of the colony. The worker bee is capable of performing a
definite amount of work and she dies when that is accomplished.
Consequently, during honey flow season when she has to work at a
tremendous pace, she lives only for about six weeks but during off
season., as in winter or in cold climate her life extends up to six
months. At Coimbatore in Tamil Nadu, which has equitable climate, A.
cerana indica worker lives for 50 days, the extremes being 44 and 54
days. Kapil found the life span to be 25-42 days from January to April
and 45 days in May in Uttar Pradesh.
Drone. The
only function of the male bee is to mate with the queen. Drone has
short tongue but does not collect food from flowers. The tongue is used
to receive food from worker bees. Drone has no wax and scent glands.
Generally it takes 3 to 6 worker bees to feed a drone. Drones are
reared and tolerated during the breeding season in spring and in some
places in autumn, when new queens are to be mated. They are driven out
of the hive to die of starvation when not needed. The normal life span
of an A. cerana drone has been worked out to be 57 days in Tamil Nadu.
The three
castes of bees depend on each other for their existence. The lonely
worker bee may not live for more than two or three days under the best
of simulated environmental conditions. The queen bee also cannot form
or even start a colony because she is physically incapable of secreting
wax, building a comb, collecting food from the field or rearing brood.
In fact, she requires the services of several wokers to feed and groom
her and to do other jobs for her. A drone would not last beyond four
hours without food. A normal colony must have a fecundated queen
capable of laying plenty of fertilized eggs and a large number of
workers of varying age as the latters’ fitness to do different tasks
depends on their age. A colony is termed ‘weak’ or ‘strong’ according
to the number of worker bees it possesses. A colony of Apis cerana
indica bees with 10,000 to 15,000 bees (906-1359 g) is considered an
average colony at higher altitudes. Drones are not necessary to the
normal welfare of a colony but they are needed only during the mating
seasons to fecundate virgin queens.
Development
The
honeybee undergoes an indirect development (metamorphosis). The four
stages of development are: the egg, the larva, the pupa and the adult.
Duration of development of worker bee of A. cerana indica is given in
Table 1. The mother queen glues or sticks a short delicate white
tubular egg, slightly curved on one side, at the bottom of the cell of
a comb. From this egg, a tiny, white larva hatches out and feeds
voraciously on the food supplied by the nurse bees. When-fully fed it
weighs more than 1,500 times of its original weight. The cell is capped
by the worker bees with a waxen cover. The fully fed larva spins a
cocoon in the cell and enters a period of rest during which it
transforms itself into pupa. The major changes in the structure of the
body occur at the cost of the fat stored in the body by the larva. The
pupa is similar in appearance to the adult bee, having developed mouth
parts, legs, wings and other appendages of the body. The adult bee
emerges after cutting the cocoon and the waxen capping of the cell.
Table 2 shows the time taken by the three castes of the Indian honeybee
in the three stages of development.
Food
of the Honeybees, Bee Flora and Honey Flow Periods
Food of the Honeybees
The
natural diet of the bees consists of carbohydrates, proteins, vitamins,
salts etc. The nectar of the flowers, which the bees collect and
convert into honey, is the source of carbohydrates and vitamins.
Pollen, the yellow powder in the flowers, is the main source of protein
and it is mixed with honey before it is fed to the larvae. The winged
bees, when they are young, also feed on this mixture. Soon they become
strong and secrete the royal jelly, which forms the food of the queen,
and of the larvae in the early states of growth. These young bees thus
act as nurse bees; but as they grow older they take up the field duties
and feed on honey only. In a hive, the nurse bees are often seen going
from one cell to another, feeding the young larvae.
For brood
rearing, it is important that there are plenty of flowers in nature as
the source of pollen and honey. For the growth of one larvae of
honeybees into an adult bee, one cell full of honey and one cell of
pollen is required. In other words, two frames of honey and pollen are
required by the bees to raise one frame of brood.
Bees can
also use the sugar syrup as food (sugar dissolved in an equal quantity
of water). Sugar is offered to supplement honey resources or in the
extreme case to save the weak colonies from starvation. Early in the
spring, when the flowers are not in abundance bees can be stimulated to
start brood rearing, and it should synchronise with the main honey
flow, so that the bees can take best advantage of it. Under proper
management, not more than one or two kilograms of sugar are needed to
be used in a year/colony. A colony of normal size should have at least
six to eight pounds of honey (two or three frames) in reserve. When the
stores fall below this level, bees should be fed artificially. If sugar
is given as a winter reserve, the syrup should be thick, prepared by
mixing two parts of sugar with one part of warm water.
To prevent
robbing by the bees of other colonies, sugar feeding should be done in
the late evening. The hive should be made bee proof that is all
crevices, holes should be closed. Then sugar is put in a feeder or in a
wide mouthed cup and placed inside the hive. Small pieces of wheat or
rice straw should be placed to serve as floats on the surface of the
liquid. Bees will sit on these floats while feeding and will not get
drowned or smeared with sugar. The sugar syrup can also be filled in
the combs. For this purpose, an empty comb is removed from the colony
and is held in the standing position in a tray. The sugar syrup is
poured on or made to run over the comb. When one side is full, the
other side can be filled. This is the safest and easiest method of
feeding the bees.
Collection
of food in honeybees is a social enterprise and more then 10,000 of
foragers may be engaged together in collecting nectar and pollen. The
foraging is designed in a way to achieve high efficiency. The foragers
sacrifice their individual foraging efficiency for colony efficiency.
When they have discovered a rich source of food, they communicate the
information through various types of dances to their hive mates. High
foraging efficiency is achieved as a result of sharing information
about location of rich food sources. Four important resources include
nectar, pollen, water and resin. Nectar and pollen are diet, water is
used for evaporative cooling of the nest in hot days and resin is used
for plugging the unwanted openings.
Colonies
managed for honey production rear 1,50,000 to 2,00,000 bees annually
and consume 15 to 30 kg of pollen and up to 80 kg of honey. The number
of trips required to pool these materials could be quite astonishing.
To collect 20 kg of pollen, approx 1-3 million foraging trips are
required. Each trip on an average measure 4-5 km of distance. Likewise,
to collect 60 kg of honey, 3 million foraging trips are required. In
brief each colony can be thought of as an organism which weighs 1 to 5
kg (biomass of b
