Effects of Photoperiods on Development and Reproduction of Trichogramma dendrolimi
摘要
Abstract
To explore the response of photoperiods during the growth process of Trichogramma dendrolimi, under four photoperiod conditions (L:D = 3:21, 9:15, 15:9 and 21:3), the characteristics of reproduction were systematically studied with the methods of reproductive biology and genecology. The results showed that longevity, daily number of parasitized eggs, oviposition period and fecundity of each female were significantly different among the four photoperiods. When illumination duration reached 15 h, longevity of female Trichogramma (47.52 h), daily number of parasitized eggs (118.94), oviposition period (41.28 h) and fecundity of each female (128.52 eggs) were better than those of other illumination treatments. By constructing experimental population life tables under different photoperiods, we found that when the photoperiod was 15 h, intrinsic rate of natural increase (rm), finite rate of increase (λ) and net reproduction rate (R0) were up to the maximum while average generation cycle (T) was shorter. To conclude, the photoperiod L:D=15:9 was most suitable for development and fecundity of T. dendrolimi. Therefore, in the process of factory production, this light ratio is beneficial to the population propagation of T. dendrolimi.关键词
