Comet assay protocol for Bombus atratus fat body and pericardial cells (Hymenoptera, bombini) at a safe concentration of mercury.

The decline of the Bombus population is closely related to the presence of environmental pollutants. Among these pollutants, trace metals represent a major concern, which includes mercury, a known genotoxic substance. The induction of genotoxicity may be demonstrated by the comet assay (a.

Thiamethoxam and picoxystrobin reduce the survival and overload the hepato-nephrocitic system of the Africanized honeybee.

Apis mellifera perform important pollination roles in agroecosystems.
