Abstract The experiment was conducted to evaluate the residual toxicity of four insecticides (chlorantraniliprole 18.5%SC, flubendiamide 480SC, diafenthiuron 50% WP and azadirachtin 10000 ppm) on three species of Trichogramma namely T. chilonis, T. pretiosum and T. japonicum. Residual toxicity evaluation revealed that diafenthiuron 50%WPwas slightly harmful to adults of all the three Trichogramma spp. Diafenthiuron led to maximum adults mortality i.e. 34.17%, 34.16% and 16.11% and azadirachtin, the least mortality i.e. 20.83%, 15.83% and 9.16% on 1st, 5th and 10th day of treatment, respectively.
