Contact toxicity study was conducted at the Insectary, Agricultural College and Research Institute, Madurai during 2017–18 to determine the safety of new insecticides/biopesticides to the Indian honey bee Apis cerana indica. The results revealed that at 24 hr after exposure, the order of mortality was: thiodicarb 75% WP @ 750g/ha (100%) > imidacloprid 17.8 SL @ 250 ml/ha (98.67%) > dichlorvos 76 EC @ 400 ml/ha (98.33%) > spinosad 45% SC @ 160 ml/ha (76.67%), spiromesifen 22.9 SC@ 500 ml/ha (73.33%) > chlorantraniliprole 18.5 SC @ 150ml/ha (70%) > chlorantraniliprole 18.5 SC @ 125 ml/ha (63.33%).
