研究了光周期、光脉冲和温度对黑纹粉蝶ＰｉｅｒｉｓｍｅｌｅｔｅＭｎｔｒｉｓ夏季滞育和冬季滞育发生、维持与终止的影响。实验结果表明：（１）黑纹粉蝶的光周期反应属于中间型，即只有在日照时数１２ｈ～１３ｈ１５ｍｉｎ范围内，才有部分越夏蛹或越冬蛹不滞育而正常发育；在日平均气温为２０．５℃的秋季，其自然种群的临界光周期为１２ｈ３０ｍｉｎ；３龄末和４龄初的幼虫为感应光周期最敏感的时期（临界光明虫龄）；（２）断光后第１０～１２ｈ，即凌晨０２：００～０４：００的光脉冲对滞育的抑制效果最好，而断光后第６～８ｈ，即夜间２２：００～２４：００的光脉冲对滞育的抑制效果最差；（３）该虫滞育发育的最适温度较低，高温对冬季滞育和夏季滞育均有一定的抑制作用，而低温则可促进越夏蛹和越冬蛹滞育的发育，加速滞育的终止。在较高温度下滞育发育的时间比在较低温度下滞育发育的时间更长。
The effects of photoperiod, light pulse and temperature on the occurrence of diapause in summer and the occurrence and maintenance of diapause in winter in Pierismelete mntris were studied. The results showed that: (1) The photoperiodic response of the black-bellied butterfly was an intermediate type, that is, only the part of the more pupae or overwintering pupae developed normally without diapause only in the period of 12h ~ 13h15min sunshine hours; In the autumn of 20.5 ℃, the critical photoperiod of its natural population was 12h30min. The larvae at the end of the third instar and the first instar of the fourth instar were most sensitive to the photoperiod (critical light age); (2) ~ 12h, the light pulse at 02: 00 ~ 04: 00 has the best inhibition effect on diapause, and the light pulse at 6 ~ 8h, that is, 22: 00 ~ 24: 00 at night, (3) The optimal temperature for diapause development was lower, and high temperature had certain effect on diapause in winter and diapause in summer, while low temperature could promote the development of diapause in overwintering pupae and overwintering pupae , Accelerate the termination of diapause. Diapause development at higher temperatures takes longer than diapause development at lower temperatures.
