The objective of this study was to investigate the reproductive performance of Bracon hebetor, a larval ecto-parasitiod of stored product moth species, on several species of lepidopteran insects, including Plodia interpunctella, Ephestia kuehniella, E. cautella, Corcyra cephalonica, Amyelois transitella, and Galleria mellonella. B. hebetor females were introduced singly into experimental arenas and allowed to sting and oviposit for five days with a fresh host given daily. Experiments were conducted using Petri dishes (100 15 mm). In life history studies, B. hebetor females were introduced singly into Petri dishes and given a single host larva every day throughout their life time. I also investigated the effect of parasitoid and host density, and size of rearing containers on progeny production and sex ratio of B. hebetor. Statistical analyses were done using PC SAS Version 9.1. The mean cumulative fecundity in five days was highest on A. transitella (106.42 5.19) and lowest on T. bisselliella (9.64 1.28Department of Entomology and Plant Patholog
