Influence of Varroa destructor invasion on chlorinated hydrocarbons concentration in bees

摘要

The aim of this study is to determine the influence of Varroa destructor invasions on the chlorinated hydrocarbon (HCH) and DDT concentration in bees from infected colonies. The study was conducted from seven apiaries in the Olsztyn area. Results showed that HCH and DDT content in bees depended on both the apiary location and V. destructor presence in the colonies. Bees from infected colonies contained less amounts of HCH. The greatest concentration of HCH and DDT was found from bees coming from apiaries located on forests, near gardens, and from rape, white mustard and weeds on waste ground. Higher HCH and DDT concentration in bees from V. destructor invasion indicates their greater activity in the environment and bringing it to the hives, the amount of which influences the increase of chlorinated hydrocarbons in the organism.
