Bean dip bioassay was performed with six insecticides on the mortality response in tomato thrips- Thrips palmi Karny and Scirtothrips dorsalis Hood. The LC50 values ranged from 1.591 to 17.018 ppm, and spinosad with the least LC50 value of 1.591 ppm at 95% confidence limit was the most toxic. It was followed by cyantraniliprole (2.425 ppm), diafenthiuron (2.396 ppm), imidacloprid (5.110 ppm), fipronil (13.560 ppm) and dimethoate (17.018 ppm). Thus, spinosad, diafenthiuron and cyantraniliprole were observed to be more toxic.
