Safety of Azadirachtin to Honeybee, Apis mellifera Linnaeus, Foragers

Safety of NeemAzal (azadirachtin 10,000 ppm) was evaluated at different dosages against Apis mellifera Linneaus Foragers. NeemAzal at the highest dosage (800 ppm) was found to be safe to honeybees with 7.58% mortality in direct toxicity test and 0.74% mortality when bees were caged in cotton field after spray. However, in foliage bioassay, it caused 17.19% mortality of foragers. Triazophos at the recommended dosage (2000 ppm) was highly toxic with mortality varying from 71.41 to 100% in different tests.
