The toxicity of nine insecticides viz., acetamiprid, clothianidin, imidacloprid, fipronil, thiamethoxam, spiromesifen, chlorantraniliprole, chlrofenapyr and diafenthiuron at recommended dose was tested on honeybee Apis mellifera L. using the dry film method. Forager bees were released into treated jars at different intervals i.e., 0, 12 and 24 hours after dry film formation. Thiamethoxam, clothianidin and imidacloprid showed high mortality while acetamiprid exhibited moderate mortality. Spiromesifen and chlorantraniliprole caused relatively less mortality.
