Abstract

The development, survival, and fecundity data of Conogethes punctiferalis (Guenée) (Lepidoptera: Crambidae) reared on chestnut (Castanea mollissima Blume), maize (Zea mays L.), sunflower (Helianthus annuus L.), hawthorn (Crataegus pinnatifida Bunge), and apple (Malus domestica Miller) were collected at 25 ± 1°C and 70 ± 5% RH. Raw data were analyzed and compared by using the age-stage, two-sex life table. The mean fecundity (F) was the highest (282.3 eggs per female) when larvae were reared on chestnut. The lowest mean fecundity (19.2 eggs per female) occurred on apple. The net reproductive rates (R0) were 134.52, 106.77, 30.29, 27.61, and 8.63 offspring on chestnut, maize, sunflower, hawthorn, and apple, respectively. The intrinsic rates of increase (r) were 0.1359, 0.1326, 0.0807, 0.0811, and 0.0448 d-1 on chestnut, maize, sunflower, hawthorn, and apple, respectively. Computer projections based on the age-stage, two-sex life table revealed the stage structure and variability of the population growth of C. punctiferalis. Our results demonstrated that although chestnut and maize were the most suitable host plants for C. punctiferalis, the moths were also able to develop and reproduce on sunflower, hawthorn, and apple.
