Life history of Bracon hebetor Say was studied on Plodia interpunctella Hubner. The life span of female(mean$pm$s.e.) was estimated to be 20.88$pm$0.97 days. The females laid eggs from the first day on after emergence and the oviposition period ranged from 11 to 27 days. But 65% of the total eggs were laid in the first 10 days. The progeny sex ratio(female/total) in the first 15 days was female-bias range from 0.51$pm$0.08 to 0.88$pm$0.02, but changed into male-bias ranged from 0.51$pm$0.08 to 0.88$pm$0.02, but changed into male-bias ranged from 0.14$pm$0.04 to 0.34$pm$<TEX>0.12. The overall sex ratio of progeny produced per female was estimated to be 0.66. Total number f progeny per female and net reproduction rate were estimated to be 205.17<TEX>$pm$<TEX>13.03 and 136.21, respectively. Other life table statistics were presented.
