Influence of adaptogens on some physiological indicators of bee colonies

Abstract

The ability of the body to resist the impact of negative environmental factors, the impact of pathogens that bear the signs of someone else’s genetic information have been proven by many researchers. The main task of the body is to maintain homeostasis of the internal environment. In honeybees protective reactions include cellular and humoral immunity. The difference between insect immunity is the absence of a specific reaction characteristic of vertebrates, an antigen-antibody. The covers of the body wall, intestines and trachea are mechanical protection against the penetration of foreign organisms from the environment into the body cavity of the bee. If foreign objects get into the hemolymph they will become a target for cellular and humoral factors of the body’s defense system. It has been shown by studies that the inclusion of sugar syrup with Apinic drug in the composition of stimulating top dressing allows to increase the flight activity of bees, while increasing the amount of pollen brought by bees, increasing the load of nectar goiter, and improving hemolymph indicators, which in turn provide non-specific cellular immunity. At the same time, the indicators of flight activity and honey crop loads that provide economically useful traits were 2,2 and 2,5 times higher compared to the control group. The level of fl ight activity at the main honey collection was higher, compared to the same indicator recorded at the supporting honey collection. In accordance with the type of honey collection, the levels of load by the nectar honey goiter in worker bees arriving in the hive diff er. Thus, the maximum level of filling of the honey goiter with nectar has been registered on both types of honey collection in honeybees from the 3rd experimental group, where propolis extract has been used as an immunomodulator as part of the honey additive. Worker bees from the 3rd experimental group have been characterized by higher levels of both the volume of circulating hemolymph and the content of hemocytes and the amino acid proline in it.
