Recent work by Alison McAfee, et al
We tested dose-response relationships of six pesticides
commonly found in wax: coumaphos, tau-fluvalinate, atrazine, 2,4-DMPF, chlorpyriphos, chlorothalonil,
and a cocktail of all six, each dosed up to 32 times the concentrations typically found in wax. We found
no effect of any treatment on queen mass or sperm viability. ... These experiments consistently
show that at realistic exposure levels, pesticides commonly found in wax have no direct impact on
queen performance, reproduction, or quality metrics. We suggest that previously reported associations
between high levels of pesticide residues in wax and queen failure are most likely driven by indirect
effects of worker exposure (either through wax or other hive products)
Honey bee queen health is unaffected by contact exposure to pesticides commonly found in beeswax
