Abstract

The effect of four commercially used insecticides on tomato crop was studied on Trichogramma chilonis Ishii and its parasitism under laboratory conditions. The toxic effect of these insecticides on 1,3, 5 and 7 day old eggs of Corcyra cephalonica (Stainton) parasitized by T. chilonis was also studied. Acephate (0.05 %) proved safer to the parasitized host as well as to the adult parasitoid. However, the emergence of adults from treated parasitized eggs was significantly lower than the untreated control.
