ResumoSummaryThe comparative topical toxicity of 16 insecticides to Apis cerana indica was determined under laboratory conditions. All insecticides were tested at the dosage recommended in India for agricultural purposes, and all were lethal to A. c. indica. Organophosphates (op) and carbamates (c) showed a similar toxicity, which was greater than that of chlorinated hydrocarbons (ch). Toxicity, assessed by the speed with which all bees were killed, was found to be in the following order, starting with the most toxic: dichlorvos, methyl parathion, phosphamidon, quinalphos (all op); carbaryl (c); fenitrothion, monocrotophos, oxydemeton-methyl, dimethoate (all op); carbofuran (c), carbophenothion (op), malathion (op); heptachlor, DDT, endrin, BHC (all ch).
