Studies were conducted for the first time on the gregarious endoparasitoid, Apanteles taragamae Viereck (Hymenoptera: Braconidae) to determine its biology on Diaphania indica (Saunders) (Lepidoptera: Pyralidae). The mean number of eggs laid per host was 24.63 and these eggs increased greatly in size before hatching. Larva passes through three instars as determined by the shape and size of the mandibles. Mean development time from egg to adult was 15.6 days at 24.26 degrees C and 80-85% r.h. The mean number of adults emerging from each host was 14.61 and the sex ratio was 1:1.31 (males:females). The mean number of eggs laid by each female was 242.6. Mean adult longevity on 20% honey was 9.30 days for males and 10.70 for females.
