The present study deals with life tables and intrinsic rate of natural increase of Bracon hebetor Say, a larval parasitoid of Corcyra cephalonica Staint, and a key parasitoid of Helicoverpa armigera Hbn. The longevity of ovipositing female ranged from 32 to 42 days with an average of 37.5 days. The total number of progeny produced was 258.9 (range 251-270). The maximum mean progeny production per day, mx was 5.5. The innate capacity of increase was 0.215 per female per day and population multiplied to 52.12 times in mean generation time of 18.38 days
