Effect of Eggplant Varieties and Temperatures on Development and Fertility Life Tables of Chrysoperla carnea (steph.) (Neuroptera: Chrysopidae)
An experiment was conducted at the Experimental farm, Faculty of Agriculture, Mansoura University, to evaluate the effect of three eggplant (Solanum melongena L.) varieties (Classic, 0111 and Anan) on development and age-specific fertility life table of the green lacewing predator, Chrysoperla carnea (Steph.) that fed upon the cotton aphid, Aphis gossypii Glover reared at three various temperatures (20, 25 and 30 ± 1˚C) and 60 ± 5% R.H. The results showed that a significant difference among the larval developmental times at the three temperature regimes within each eggplant variety. Similarly, the entire development (egg-adult) of C. carnea was significantly differed among host varieties, hosting aphids, within each temperature regime. For the life table parameters, the highest value of gross reproductive rate (GRR) for C. carnea was obtained when provisioned with aphidsreared on Classic variety at 30˚C. Moreover, the longest mean generation time (T) and doubling time (DT) were achieved when the predator fed upon prey that reared on Anan and 0111 varieties, respectively. Further, the lowest and highest values of the net reproductive rate (Ro) were obtained when the predator provided with prey from Classic and 0111 varieties, respectively. Additionally, the highest value of the intrinsic rate of increase (rm) was obtained when the A. gossypii fed on Classic variety at 30 °C. It can be concluded that both eggplant verities and temperature had significant effects on the developmental time and life table parameters of the predator. Hence, to optimize the mass rearing of A. gossypii as a preferred prey for C. carnea, Classic variety of eggplant has to be considered. As well, the range of temperature between 25-30°C would maximize the performance of predator under rearing conditions. This information on tritrophic interactions and subsequent life table estimates of C. carnea improves IPM programs of aphids.
