Effect of plant nitrogen and silica on the bionomics of Sesamia calamistis (Lepidoptera: Noctuidae)
Bulletin of Entomological Research 83 (3), 405-411
Abstract: Increasing nitrogen doses significantly increased larval survival, larval weight and female fecundity. A significant, positive relationship was found between moth fecundity and female pupal weight. Nitrogen had no effect on larval and pupal developmental time but increased adult longevity. Intrinsic rate of increase, and the net reproductive rate, were positively correlated to leaf and stem nitrogen, while generation time was negatively correlated. Silica had the opposite effect from nitrogen on larval survival. Increasing silica supply reduced ultimate larval survival from 26% to 4%. Immature developmental time, larval and pupal weight, pupal survival, female fecundity, egg viability and adult longevity of Sesamia calamistis were not affected by silica application.
