| 摘 要： | 研究结果表明 :菜粉蝶光周期反应的感应虫期为 2～ 4龄幼虫 ,以 3龄幼虫的感应性最强 ,在 1 7℃条件下 ,其临界光周期为 1 1h44min。滞育蛹在高温下可以解除滞育 ,但时间较长。低温对滞育蛹有活化作用 ;低温处理明显降低滞育蛹在高温下的历期。种群内个体间滞育的解除异质性较强

Effect of Photoperiod and Temperature on Diapause of Pieris rapae |
| |
| Abstract: | The study results show that the second～fourth instar larvae of Pieris rapae are significantly sensitive to photoperiod, the third instar larva being the most sensitive; the critical photoperiod of P. rapae under 17℃ constant temperature in Nanchang is 11h 44 min. High temperature can terminate the diapause of this insect, but the termination of diapause requires longer time under high temperature than under low temperature. The vernalization of low temperature to diapause pupa significantly reduces its duration at high temperature. The population of P. rapae has great heterogeneity in the termination of diapause. |
