Some biological aspects of the egg parasitoid, Telenomus busseolae (Gahan) (Hym., Scelionidae) on the Sesamia nonagrioides Lef. (Lep., Noctuidae) eggs

Öz

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±
