Biological features of the seasonal dynamics of Varroa destructor (Anderson and Trueman, 2000) in the conditions of Poltava region

Abstract

The data of the determination of infection rates of Varroa destructor honey bees in the climatic conditions of Poltava region depending on the season, taking into account the biological characteristics of parasitic ticks are presented. It has been established that the seasonal dynamics of varroasis is characterized by an increase in extensiveness of invasion and the abundance index in the summer-autumn period of the year, and the rates of intensity of invasion in winter and summer. It is proved that during the year the number of ticks on one worker's bee ranges from 1 to 8 specimens. Biological features of ticks are characterized by activation of parasitism on bees in summer (up to 8 specimens of imago) and in autumn (up to 7 specimens).
