Abstract

Life table data of Trichogramma embryophagum (Htg.) and Trichogramma dendrolimi Mafatsumara were collected on eggs of Corcyra cephalonlca Stainton. The net reproductive rate (Ro) of T. embryophagum was 60.23 and that of T. dendrolimi 33.98, the intrinsic rate of natural increase (rm) was 0.292 and 0.305 and net generation time (T) was 14.03 and 13.25 days, respectively. For mass production, adult females of T. emhryophagumshould be utilised for 5 days and T. dendrolimi for 2 days.
