摘要
室内研究了在同一温度(25℃)3、种不同光照条件(8L∶16D、12L∶12D、16L∶8D)下饲养的菜蛾盘绒茧蜂,其后代在4种不同温度(13、15、17、20℃)和2种光周期(8L∶16D、11L∶13D)下饲养的滞育率变化情况。结果表明:母代的光照经历、子代饲养温度和光照周期这3个滞育诱导因素都会显著地影响滞育率。母代的光周期经历与子代诱导滞育的温度或光周期之间、子代诱导滞育的温度与光周期之间均存在交互作用,但3个因素间的交互作用不显著。母代在长日照条件下饲养可以降低子代诱导滞育的临界温度。子代在较低温度下饲养,母代经历的光周期对子代滞育的发生影响不大,甚至没有影响;但当子代在相对较高温度下饲养,母代经历的光周期对子代滞育发生的影响十分明显。
Effect of maternal photoperiod experience on diapause incidence of Cotesia plutellae was examined in laboratory by exposing mother generation （GO） to 3 photoperiod regimes （8L： 16D, 12L： 12D and 16L：8D） at 25℃, and exposing their offspring （G1） to 2 photoperiod regimes （8L： 16D and 11L： 13D） at 4 temperatures （13, 15, 17 and 20℃ ）. The results indicated that all three diapause-inducing factors, maternal photoperiod experience, offspring rearing temperature and photoperiod, had significant influence on diapause incidence of the parasitoid. Interactions between any two factors were significant. However, the integrated interaction among three factors was not significant. Long day-length experience in GO lowered the critical temperature for diapause-inducing in G1. The photoperiod experience in GO had least influence, even no influence on the incidence of diapause when G1 was reared at lower temperatures, but it had an obvious effect on the incidence when G1 was reared at relative higher temperatures.
