DEVELOPMENT OF BEE COMMUNITIES AND THEIR PRODUCTIVITY IN THE VASYUGAN BOGS

Bee lifetime and their productivity in the area of the Vasyugan bogs varies from month to month. Air temperature and plants, which are in flower at this period influence bee lifetime. Thus, the potency of bee community in May was 28013 worker-bees, honey bag burden – 22.20±0.50 mg of honey dew; there were better climate conditions in June and the number of bees in a community was 34549; each burden of a bee was 24.00±0.69 mg of honey dew. The most favourable climate conditions were in July and the potency of bee communities was 54965 and burden was 26.40±0.78 mg. In August bees overworked on honey gathering and their number in a community was reduced up to 21045, honey bag burden was reduced up to 19.70±0.79 ng of honey dew. The authors investigated the plants and found out that more than 50 plant species grow on the Vasyugan bogs where bees gather honeydew. But the lack of polliniferous insects prevents development of bee communities. When it is warm, bee communities gather pollen from the willows (Salix L.) and then from blowball (Taraxacum Wigg.). The pollen trap showed daily yield of bee community on 20–30 g. This amount of pollen that get into bee communities bees use for brood rearing. Regardless severe climate in the Vasyugan bogs area (55° mid latitude higher) it is possible to arrange commercial bee yards with high marketability:80 kgand more of honey yield and2300 gof beewax produced by each bee community
