The biology of Trichogramma chilouis Ishii was studied on eggs of its factitious host Corcyra cephalonica (Stainton) and its natural host Helicoverpa armigera (Hübner) at 25 ± 1, 65 ± 10 per cent RH and 16:8 h L: D. The developmental period of female progeny was significantly shorter on eggs of C. cephalonica compared to H. armigera. However this trait was not significantly different on both the host eggs when male progeny was considered. Similarly, fecundity of the female parasitoid was significantly higher on eggs of C. cephalonica compared to H. armigera hut the number of female emerging/day was not significantly different between two hosts. Number of male and unemerged progeny was also significantly higher on C. cephalonica compared to H. armigera eggs.
