The effect of diverse plant origin insect growth regulators on emergence and survival of endoparasitic Wasp, Apanteles obliqua (Hymenoptera: Braconidae) was studied in order to estimate the safety margins between the IGRs required to kill the pest and its parasitoid. The per cent adult emergence from the sprayed cocoons with IGR's was in the order of: CSM 1% (93.34%) > Aza 1% = CSH 1% (83.33%) > THA1% = MSH 1% = Neem oil (76.67%) > CSM 5% = CSH 5% (73.33%) > MSH 5% (56.67%) and the survival of the adults were: Aza = THA 1% = CSM 5% = CSM 1% (96.67%) > CSH 5% = CSH 1% = MSH 1% (73.33%) > MSH 5% = neem oil 1% (53.33), indicating safe use in IPM programme with exception to MSH 5% and neem oil 1%.
