The state of the fat body of bees and their productivity

Goal. To find out how the development of the fat body of bees in the autumn period affects the condition of bee colonies and the manifestation of their productivity in the season following wintering. Methods. Zootechnical (selection of groups of analogs, assessment of bee colonies, accounting for the number of brood); mathematical and statistical (assessment of the reliability of the results obtained). Biometric processing of data was carried out on a PC using MS Excel software using built-in statistical functions. Results. The growth of the fat body of bees was observed during the period of replacing summer bees with winter bees and preparing them for wintering. To ensure normal conditions of existence and development, the bee family should have reserves of carbohydrate and protein feed and the possibility of their replenishment. More commercial honey was obtained from those bee families in which bees had a higher rate of fat body development. Conclusions. It was established that the productivity of bee colonies was directly dependent on the development of the fat body of bees. The normal physiological formation of the organism of bees of the autumn generation depended on the presence of proteins in their feed, therefore, in case of their deficiency, protein feeding of bees was necessary.
