The Effects of Pesticides on Queen Rearing and Virus Titers in Honey Bees (Apis mellifera L.)
Insects, 2013 The effects of sublethal pesticide exposure on queen emergence and virus titers were examined. Queen rearing colonies were fed pollen with chlorpyrifos (CPF) alone (pollen-1) and with CPF and the fungicide Pristine® (pollen-2).
