Abstract:
Because of lack of nectar and pollen collections and a sufficient quantity of feed in the nest, bees eat sugar syrup. The aim of the research was to study the use of the natural bioregulator "Moldstim" in the feed for bees in autumn and spring. It has been demonstrated that the optimum dose of the natural bioregulator in the feed for bees must be 50 mg per liter of sugar syrup. The utilization of the natural bioregulator in bee feeding in spring ensures the increase of their productivity by 8,62-25,28 %.
