| Abstract | ||||
| Longevity, fertility, preimaginal, developmental time and superparasitism of two strain populations of Eretmocerus mundus Mercet (Hymenoptera: Aphelinidae), parasitizing Bemisia argentifolii Bellowsand Perring (Homoptera: Aleyrodidae) were reared on two host plants, Lantana camara and Convolvulus arvensis, at two temperatures 24 ± 1 and 30 ± 1°C. The populations of E.mundus were provided from Isfahan (I parasitiods) and Mazandaran (M parasitoids) provinces, which are located in central and northern Iran, respectively. Significant differences in preimaginal developmental time were not detected between populations at different temperatures and host plants. Adult longevity was greatest at lower temperature than at higher one. Mean longevities varied from 13.33 days at 24 ± 1 °C to 6.6 days at 30±1°C. Fertility on Convolvulus arvensis was higher than on L. camara and at 30±1°C was higher than other temperature. Sex ratio of "M" population depended on temperature and host plant, but in "I" population, all progeny were female. Significant differences in superparasitism were found between populations, temperatures and host plants. Superparasitism or self-superparasitism was observed in "M" parasitoids, while "I" parasitoids completely avoided superparasitism. | ||||
