As long as the volume of a bee hive is adequate, hive design will not influence honey production. Good hive design will make management possible and easier for beekeeper.

These are the top-bar hives, where bees build their comb attached to a top-bar that can be lifted out of the hive.

A movable-comb or movable-frame hive enables detailed hive inspection, colony division or selective breeding and queen rearing, as well as providing for ease of honey removal. In frame

hive design will not alter honey yield. Bee hive technology may be divided into

three types:

production and availability in relation to local honey potential and cash return. These vary according to geographical location and temperament of both bees and beekeeper.

DEAR FRIENDS...

We bring you 16 pages bursting with fresh news of beekeeping. If you want evidence of how beekeeping can strengthen people’s livelihoods, then read two items in News around the World: Action for Development in Ethiopia and the report from Tecla David of Mozambique. Many beekeepers are now travelling world-wide and Nepal is one of the most popular destinations. Many ask us for information on beekeeping in Nepal. On page six Otto Boecking and Wolfgang Ritter give a report of the honeybee disease situation in Nepal, that also reflects on the impact of the introduction of exotic Apis mellifera. Starting on this page Peter Paterson gives an excellent review of the pros and cons of traditional hives, top-bar hives and movable-frame hives. On page ten, a new way of getting information to the people that most need it is discussed. See Look Ahead for the new dates for Apimondia 2001; Zoom into the Philippines; Grow some loofahs; Learn about a Belgian organisation that has been fair trading in honey for 20 years; and finally, sit back and consider a beekeeping trip to Mars.

Bees for Development has plenty of views to share!

situations.

This provides an example of frame hive beekeeping taking over from traditional hives. Success perhaps, but at the expense of the traditional, small-scale beekeeper.

SUCCESS WITH FIXED COMB HIVES The existence of traditional hives is testimony to their success. These are fixed comb hives and have until recent times been used throughout the beekeeping world. Traditional hives have the great advantage of being cheap and easily made from locally available materials.

The economics are extremely good. The inputs are time and traditional knowledge, and the outputs are honey and beeswax. Usually there is no cash outlay. The quality of honey made by honeybees is the same regardless of hive design. The care taken in harvesting and handling honey by the beekeeper is what

decides quality. Very good quality honey may be obtained from traditional hives. Market forces and price incentive will encourage a traditional beekeeper to produce overnight clean, selected honey. Nevertheless traditional beekeeping is on the decline. In many areas it is practised far less than 30 years ago, if at all. The main reason for this is theft and this is why large-scale beekeeping is virtually impossible in most of Africa. Sadly, in more populated areas the only safe place to keep bee hives is close

to the homestead. A further current problem with traditional hives is that many are made

from hollowed out logs obtained from large trees. In much of Africa most suitable trees and forests

have now disappeared and it would be a pity for any more to be turned into hives. However there are alternatives as demonstrated by the many traditional hives made from woven grass and various fibre materials. In view of the widespread adoption of this very successful beekeeping practice, great care needs to be taken in suggesting something better.

SUCCESS WITH TOP-BAR HIVES Top-bar hives have no frames requiring an accurate bee space and therefore their construction is simpler than frame hives. Only the top-bar width needs to be well made and even its width is not very critical so long as there is a good starter guide.

Since the late 1960s top-bar hives have been widely advocated in central Africa. Some have been successful but there are many cases where they have not been. There are too many apiaries in total neglect, probably because these hives and their use were either never understood or there was some serious fault with them, probably the top-bars.

A well made top-bar hive in stationary beekeeping can be used in the same way as a frame hive except for mechanical extraction of combs and the return of empty

combs to the bees. Migratory beekeeping ideally requires wired frames although traditional hives are sometimes migrated in Ethiopia.

The temperament of the African honeybee is such that it is not

Honeybees will very frequently not follow the wooden lips even if they have a smearing of wax. Instead of following the length of the top-bar the bees build across the bars attaching

combs to several bars thereby removing all benefit of movable combs. Top-bar hives do need management. If they are single chamber, as most of them are, they have limitations in volume and so it is very important that they are harvested regularly and also that

excess old or pollen-clogged combs are removed so that there is always room for new comb construction. If management is not happening these old combs can block the way for new comb and honey production.

A potential of top-bar hives, which has not yet been much exploited, is in the use of muilti-chamber top-bar hives. have described this in an article entitled “A Langstroth hive

a certain discouragement to their use. The most serious problem that arises from top-bar hives is that the top-bars are not working. When they do not work it is a design fault. The Greek basket hive had top-bars that were rounded on the underside and this seemed to encourage the honeybees to build their combs at the lowest point. The Kenya top-bar hive was originally made with a V-edge and the bees attached their comb to that quite well.

The conclusion must be that properly done, in good conditions, there is no question that top-bar hives can work very well. Top-bar hives that are badly made and carelessly promoted waste a lot of time and resources.

The classic case of this is the European straw skep. The simplest skeps were single chamber hives. Then the idea came in for use of supers whereby a smaller skep was placed on the main skep that

The only drawback is that they do not lend themselves to advanced management, but if such management is in fact not happening anyway, that does not matter.


A manned mission to Mars (including landing) will take about two years. A one way

trip will take about eight months, but depends heavily on the trajectory flown. The length of stay on Mars might last one to three months. by Anton G Branz, Germany The crew would consist of two or three members and would need among other things food, oxygen, and water. The freshness of food decreases over time. To eat canned food for this length of time

would be unappetising and can cause physical as well as mental health problems. The weight of such a large amount of food plus its containers would be huge

and oxygen requirements need to be considered.

The required water quantity is somewhat less because of its potential to be recycled, and biological waste can be entrusted to the infinite deepness of space

as a hidden message from Earth!

RIQLOGICAL CYCLES duction of the masses needed above can be reduced by the use of three biological cycles which

have food plants as a central point and we can make use of the symbiosis of plants and humans.

The first loop is the oxygen-carbon dioxide loop. Humans breathe in oxygen and exhale carbon dioxide. Plants take in carbon dioxide and release oxygen. A sufficiently large quantity of plants can be used as oxygen generators, which reduces the required amount of oxygen and related containers considerably.

The second loop is the fruit-compost loop. Humans eat the fruits of plants and leave digested “compost” as fertiliser for the plants, that convert compost to appetising titbits: cabbage, carrot, chard, dry bean, onion, peanut, radish, rice, soya bean, spinach, sweet and white potato, tomato or wheat. And everything is quite fresh. A sufficiently large quantity of plants can be used not only for oxygen production but also

as food producers, which would reduce the quantity of food to be transported.

The third loop is the water loop. Used water can eaned and used for watering plants. Plant soil Jo the cleaning to a certain extent as happens here on Earth, and it becomes drinking water. Part of the water is taken from the plant’s roots and .

released via the leaves (as oxygen is released). This water can be condensed (and after mineral

enrichment of course) used as drinking water.

But why does a beekeeper take a remote interest In a trip to Mars?

Nowadays it can be even more modern. Bumblebees can be bought in a cardboard box and put into a greenhouse to do their job. Bumblebees are more cost-effective and reliable than human pollinators. Potlination does not necessarily have a binary result je pollinated or not. There can also be an intermediate result: poorly pollinated by too little pollen. A prerequisite for proper fruit production is proper pollination. Insects do this quite well in nature.

During a long time and distance of space flight one might use astronauts with a little brush in their hand

as pollinators of their own food to avoid dangerous boredom. Pollination by bees in a closed house with transparent walls and ceiling is apparently not possible. An experiment of this kind was done by the

American Biosphere II test installation. In a bee flight room with non-transparent walls and artificial illumination, bees can do their job very well.

At one side of the hive were the three frames, on the other side a feeder with sugar syrup.

Honeybees are present in Nepal’s temperate mountain region and in the hot, humid, sub-tropical terai region. Indigenous honeybee species are Apis cerana, Apis dorsata, Apis florea and Apis laboriosa. Honey hunting by professional hunters and collective village groups is a long established activity in Nepal, exploiting the giant honeybee Apis dorsata and the rock bee Apis /aboriosa. Beekeeping with Apis cerana is part of Nepal's cultural heritage. The most common type of beekeeping is with Apis cerana in log, wooden box, clay and wall hives, which have fixed combs. Various projects have introduced several types of movable-frame hives, supplemented by training and extension services, in attempts to improve beekeeping management techniques with Apis cerana.

The European hive bee Apis mellifera has been recently introduced, mainly in the Kathmandu Valley. Colonies of Apis mellifera are imported into Nepal in expectation of greater productivity, and to overcome supposed problems with Thai sacbrood disease in Apis cerana. No government .

regulations exist concerning the importation of exotic species.

INDIGENOUS HONEYBEES IN THE HIMALAYAS Since 1993 the Austrian Ministry of Foreign Affairs has supported a project to conserve and utilise indigenous honeybees in Nepal. In 1999 the project was widened to include the Hindu Kush Himalaya Region. The project is managed by Austroprojekt GmbH (Vienna) and based at the International Centre for Integrated Mountain Development (ICIMOD) in Kathmandu. B&D will bring regular features about the wor of the project throughout 2001 and 2002. To provide context for the importance and need for this project, we are starting the series with this summary of the honeybee disease situation in Nepal.

Bee diseases reduce potential

EXPLANATION PLEASE!

The presence of bee disease is one of the main problems facing beekeepers world-wide. A short survey of the present status of bee disease in Apis cerana, with particular concern for Thai sacbrood virus infestation, and Varroa jacobsoni and Tropilaelaps clareae mite infestation in Apis mellifera beekeeping was initiated by AP!-Promo-GTZ (Germany)

HONEYBEES

1998. Information and experiences were exchanged with local beekeepers about these diseases and possible control strategies. in March

Apis cerana

An Asian species of honeybee that can build a series of parallel combs and can be kept in hives.

Apis dorsata

Asian species of honeybees. These bees build single combs and cannot be kept inside man-made hives.

Apis mellifera

This is the species of honeybee found naturally throughout Africa, Europe and the Middle East. In recent years European races of Apis mellifera have been introduced to many countries of Asia, including Nepal.

Apis florea Apis laboriosa

Survey This survey was only a short study. The information source was direct inspection for clinical symptoms of randomly selected bee colonies in each apiary. All colonies investigated were in movable frame hives, which allowed a check of the colonies frame by frame. Bees and brood samples were collected for laboratory analysis.

Diseases in Apis cerana Based on clinical symptoms, Thai sacbrood virus, European foulbrood and Varroa jacobsoni were present in the inspected Apis cerana colonies. Thai sacbrood virus was found in three colonies (out of 34 inspected).

Clinical symptoms are not enough to determine which disease actually threatens the bee colonies. This is because many bee diseases show similar clinical symptoms although they have different causative organisms. To determine whether Thai sacbrood virus was the cause of the clinical

symptoms, laboratory analysis was carried out: in two of three cases this confirmed the clinical symptoms. Visiting three apiaries the beekeepers claimed that their colonies suffered from Thai sacbrood infestation. Any clinical symptom could prove the beekeepers’ assumption. In these cases the bee colonies suffered from poor pollen and honey supplies, and the bees were already eating their own brood. In two cases the colonies were being robbed by other colonies. All these cases showed poor management of the colonies by the beekeepers. There are no chemical cures for Thai sacbrood disease, and many beekeepers are treating their colonies with antibiotics, which might increase the development of resistance to bacteria in the future. EFB was found in 11 colonies (out of 34 inspected) and confirmed by laboratory analysis. The infestation level with EFB of all colonies investigated did not reach destructive levels, since the bees themselves try to reduce the disease by hygienic nest cleaning behaviour.

DISEASES European foulbrood

European foulbrood (EFB) is primarily caused by the bacteria Mellisococcus pluton. EFB occurs in Apis cerana and Apis mellifera.

Sacbrood

This disease is caused by the Sacbrood virus and is found in Apis mellifera.

Thai sacbrood

This disease is caused by the Thai sacbrood virus, and is found in Apis cerana.

Tropilaelaps clareae

This is a mite. It occurs naturally in Apis dorsata and does not cause problems for this species. Tropilaelaps clareae does cause problems when present in Apis mellifera,

Varroa jacobsoni This

is a mite. It occurs naturally in Apis cerana and does not cause serious problems for this species. Varroa jacobsoni does cause problems when present in Apis mellifera.

The incidence of Varroa jacobsoni is low in Apis cerana and it causes no notable damage. Although this ectoparasitic mite regularly infests Apis cerana colonies, many Apis cerana beekeepers in Nepal have never seen a Varroa mite in their colonies, due to the low infestation levels.

Diseases in Apis mellifera During this survey five beekeepers, keeping a total of 155 colonies of Apis mellifera were visited. 14 randomly selected bee colonies were carefully inspected for clinical symptoms of bee diseases.


Based on clinical symptoms, Sacbrood virus, EFB, Varroa jacobsoni and Tropilaelaps clareae were present in the inspected Apis mellifera colonies. All inspected bee colonies were infested

with the Varroa mite, but at very low levels.

rie

This is because the beekeepers treat their colonies with acaricide regularly throughout the whole year. This will create problems in the future. Already it is well known that chemical residues of the treatments accumulate in honey and wax, a basis for the development

of resistant mites. Honey contaminated with chemical residues will not be acceptable for

international markets.

Some of the colonies were highly infested with Tropilaelaps clareae to the extent that

secondary infections had already started to destroy the colonies. Sacbrood disease and EFB were evident. Both diseases, and bees with deformed wings (possibly due to the deformed wing virus) are indications of secondary infections. Laboratory analysis

confirmed the clinical symptoms of Sacbrood virus and Deformed wing virus.

The moment the beekeepers migrate their Apis mellifera colonies into the terai in October Tropilaelaps clareae mites start to infest the Apis mellifera colonies.

colony theft leads to the problem that bee colonies are kept near to the farmers’ houses. Since the foraging range of honeybees (especially Apis cerana) is limited this hinders the bees from

The survey of existing Varroa control methods revealed that there is an urgent need to establish additional and new control methods for use by Apis mellifera beekeepers, since the intensive use of chemical acaricides has limitations.

The project has focussed on providing top-bar hives and protective clothing on loan, as well as offering basic training.

This honey was sold for US$770, which is about the

WORKING IN KENYA

Educating girls before they drop out of the schooling system can make a vital contribution to the elimination of poverty in rural Africa. If women have a good grounding in agricultural knowledge they are better able to run productive farms, to raise healthy, well-nourished families and to secure an education for their own children. How can we reach this group? Existing agricultural extension services, which in any case tend to be under-resourced and fail to meet the demands of the poorer sectors of the farming community, often marginalise women. Girls are often removed from primary school before completion.

Where economic necessity requires families to choose which children to support in education, it is rare for sisters to receive priority over brothers.

Working in Kenya, The DFID Livestock Production Programme has supported a project bringing together extension agents, community-based organisations, an educational NGO, a media NGO and extension researchers, to make a concerted effort to find out from poor households what they need to know about livestock, and then find the best way to deliver that information. By allowing disadvantaged groups to highlight the gaps in their knowledge and to suggest the topics on which they would like to receive information, the project is researching how best to respond flexibly to real need in the community. Farmer groups identified previously ignored livestock species, such as rabbits and bees, as being important sources of income and nutrition for poorer families, and particularly for landless farmers and women. Because of the unique nature of this project - not tied to any particular agricultural research institute - livestock information can come from the most appropriate source and therefore respond to the needs of the livestock rearers themselves.

The information has been presented using the cartoon character “Wambui” in an illustrated storybook style. Wambui is a young girl living with her mother and baby sister on a typical smaltholder mixed farm. She sets out to soive the family’s problems by talking to her neighbours and to the local extension officer. The stories are set in the project’s pilot location Embu District in Kenya. The project has been running for eight months. It has already mapped formal and informa! information exchange networks, and community information needs have been identified. Six different booklets have been delivered in the pilot location, each with a print-run of 6000. Three more are in preparation. School teachers have formed focus groups to give feedback on the impact of booklets on children, and repeat-transect surveys have shown measurable change in knowledge amongst adults following delivery of the booklets. The booklets have proved very popular with all the groups. A measure of popularity is that some of the schools insisted on the children returning the booklets so that they may be retained as a schoo! resource — instead the project provided more copies.

approach to information supply, it is possib to deliver knowledge effectively and sustainably in support of the very diverse livelihood activities pursued by the rural poor. “Wambui” has had considerable impact on farming communities even as a one-year, low-cost pilot-project. Based on this success there is a need to explore further opportunities for contributing to poverty elimination by linking farming information to the delivery channels used by rural education and healthcare services. We are pleased to mention that this Wambui Project took second place in the DFID Research Award Competition.

MAYA FAIR TRADING

MIEL MAYA HONIG “There are people behind honey” “Fair Trade is an economy in the service of men, and not men in service of the economy” Miel Maya Honig is a small, Belgian non-for-profit organisation that works in partnership with marginalised

beekeepers organised in co-operatives. This partnership respects the Fair Trade criteria, of which the principles are: a fairer price for honey, an advance payment to the producers, a long-term relationship and collective organisation of the producers.

a

Miel Maya Honig started working 25 years ago with beekeepers in Guatemala. As a consequence of the repression in Guatemala in 1982, the activity shifted to the other side of the boundary, to the south of Mexico (Chiapas). Now 500 beekeepers and their families (3000 people), benefit from the action of Miel Maya Honig in Guatemala and Mexico.

Maya Fair Trading annually imports approximately 100 tonnes of honey, from Mexico and Guatemala. 50% of the Maya honey is sold on the Belgian market.

The remaining honey is exported to France, Norway, Switzerland and The Netherlands. Maya Fair Trading sells jars of muiltifloral, butter, and orange blossom honey; honey sweets, lollipops and cookies; and honey beer. On 20 October 2000 Maya Fair Trading organised a seminar in Brussels, Belgium about fair trade. Participants were introduced to how Maya Fair Trading operates, with a presentation from each “link” in the chain:

producer, exporter, importer, quality controller,

manufacturer and distributor. Next, participants chose between two workshops: Workshop / discussed the modalities of fair trade: What is a fair price? How can we fix and

In many parts of the tropical world, young loofah gourds (less than 10 cm long) are harvested for culinary purposes. The ridged loofah is considered the tastiest of all, as the common and other varieties occasionally develop a bitter taste. Tender loofah fruits can be added raw to salads or cut up in soups in the same way as okra. The real gastronomic utility for this vegetable ties in its ability to substitute for zucchini or squash, or for egg plant in parmigiana. In Japan, one of the world’s biggest producers and consumers, the fruit is sliced and sun-dried. In India the gourds are popular in curries, while Malaysians relish the young leaves, raw, and the Annamese people of China like to eat the male flowers and flower buds. The blooms can be dipped and sautéed. Jams and jellies are prepared with the flowers.

November 2001

South Africa has great pleasure in inviting beekeepers and members of the bee community from around the world to share in the celebration that is APIMONDIA 2001 The Apimondia Congress sets out to attract a wide range of people: from the hobbyist beekeeper to the large-scale commercial beekeeper; representatives from the seed and fruit industries; those in development programmes, trainers and extension workers; as well as pollinators, packers, equipment vendors, apitherapists, entomologists and academics, farmers, growers and their representatives.

The Opening Ceremony featuring traditional African entertainment will be an event to remember. Technical sessions will run in parallel throughout the Congress. Poster presentations will remain on show, together with an exhibition with the theme Bees and beekeeping on the African continent. Local honey will be displayed in a competitive honey show, with honey tasting.
