Laboratory experiment was conducted at Bio-Control Unit, Division of Agril. Entomology, College of Agriculture, Pune during 2018-19, with a view to assess the safety of emamectin benzoate along with thiamethoxam and dimethoate to egg-larval parasitoid, Chelonus blackburni Cameron. The results revealed that emamectin benzoate at higher and lower doses tested significantly lesser adverse effect on adult mortality of C. blackburni compared to thiamethoxam and dimethoate. The higher (0.0011%) and lower (0.00055%) dose of emamectin benzoate tested was recorded 1.66, 3.33, 11.66 and 5.00, 11.66, 15.00 per cent adult mortality after 12, 24 and 48 hours amongst the tested insecticide. Whereas, thiamethoxam (0.005%) and dimethoate (0.06%) registered significantly highest mortality of 76.66 per cent and 100.00 per cent, respectively at 48 hours after treatment and indicated that dimethoate was observed extremely toxic and unsafe to C. blackburni.
