Temperature dependent development of the parasitoid Colpoclypeus florus (Hymenoptera: Eulophidae) in the laboratory
Journal of Economic Entomology 93 (6), 1627-1632
Abstract: Development, fecundity, and longevity of Colpoclypeus florus (Walker), a parasitoid of Adoxophyes orana (Fischer von Röslerstamm) (Lepidoptera: Tortricidae), were studied under laboratory conditions at different constant temperatures. Developmental time from egg to adult was inversely related to temperature and at 25°C was 12.81 ± 0.19 d. No adults emerged at 30°C. The thermal units required for development from egg to 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 longevity was 11 ± 1.25 d at 17, whereas it decreased to 4.5 ± 0.4 at 25°C. Honey significantly increased longevity for both males and females. The highest net reproductive rate was 30.739 at 17°C, whereas the highest intrinsic rate of increase and the shortest doubling time occurred at 25°C.
