Does ingestion of neem-contaminated diet cause mortality of honey bee larvae and foragers?

摘要: We have tested the hypothesis that ingestion of neem-based products increases mortality Apis mellifera foragers and larvae. For this purpose, we conducted bioassays in which bees different ages were submitted to neem concentrations. Foragers treated with two concentrations a product (120 mg a.i./l 480 mg a.i./l) mixed water sugar solution (syrup). The larvae reared vitro larval diet (60 mg 120 mg a.i./l). Neem increased bees, effects dependent on age concentration. higher concentration had reduced survival rate comparing other treatments. Larvae more susceptible than because, both concentrations, all died before reaching prepupa stage. discuss potential negative honey suggest methods minimiz...
