Abstract

Development, fecundity, and longevity of Colpoclypeusflorus (Walker), a parasitoid of Adoxophyes orana(Fischer von Röslerstamm) (Lepidoptera: Tortricidae), werestudied under laboratory conditions at different constant temperatures.Developmental time from egg to adult was inversely related totemperature and at 25°C was 12.81 ± 0.19 d. No adultsemerged at 30°C. The thermal units required for development from eggto adult were 232.56 ± 19.5 degree-days. Female C.florus oviposited (mean ± SEM) on average 30.7, 57.4, 46.6,and 34.1 eggs at 15, 17, 20, and 25°C, respectively. Adult longevitywas 11 ± 1.25 d at 17, whereas it decreased to 4.5 ±0.4 at 25°C. Honey significantly increased longevity for both malesand females. The highest net reproductive rate was 30.739 at 17°C,whereas the highest intrinsic rate of increase and the shortestdoubling time occurred at 25°C.
