Biological aspects of the egg parasitoid, Telenomus busseolae (Gahan) (Hym., Scelionidae) on the Sesamia nonagrioides LeI. (Lep., Noctuidae) eggs were studied in a growth chamber at different temperatures and 65±10% of relative humidity. The longevity of T. busseolae females was found to be 12.1, 10.2, 9.2 and 3.9 days at 20, 25, 30 and 35±1°C respectively. T. busseolae parasitized approximately 65.7, 84.55 and 94.45 eggs of S. nonagrioides during the life span at given temperatures. T. busseolae was not parasitized S. nonagrioides eggs at 35± 1°C. The life table of T. busseolae was examined and the net reproduction rate (Ro) were 23.20, 44.56 and 54.95 female/female at 20, 25, and 30±1°C respectively. Intrinsic rate of increase (rm) were 0.088, 0.172 and 0.301 female/female/day and mean genaration time (To) were 35.48, 22.38 and '13.44 days, respectively. .The results show that 30±
