摘要: 为了阐明环境因子对绿盲蝽Apolygus lucorum Meyer-Dür卵滞育诱导作用, 测定了3个温度和6个光周期组合处理对绿盲蝽的滞育诱导和绿盲蝽光周期感应的敏感虫态, 系统调查了绿盲蝽在不同温度和不同光照组合下所产卵的孵化率。结果表明: 绿盲蝽的敏感虫态为1龄若虫; 在17℃, 20℃和23℃3个不同温度下, 光照时间小于14 h能够促进滞育诱导, 光照时间大于14 h则有利于个体的发育而抑制滞育产生。短光照对滞育的诱导作用具有累积效应。光照时间在10~14 h范围内, 滞育率随着温度的升高而降低; 光照时间大于14 h, 温度不再对滞育诱导起作用。在 17℃, 20℃和23℃条件下, 绿盲蝽的临界光周期分别为 13 h 10 min∶10 h 50 min (L∶D), 12 h 58 min∶11 h 2 min (L∶D)和12 h 51 min∶11 h 9 min (L∶D), 随着温度的升高, 临界光照长度缩短。结果说明, 绿盲蝽属于长日照型昆虫, 光照周期是其滞育的主要诱导因子, 温度对于滞育诱导起辅助作用, 秋季低温能够促进其滞育诱导。

Abstract: To understand the effects of temperature and photoperiod on egg diapause induction of Apolygus lucorum Meyer-Dür, the hatch rate of A. lucorum eggs laid by those rearing at 3 temperatures and 6 photoperiods were systematically investigated. The results indicated that the 1st instar larvae of A. lucorum was the sensitive stage. The daylength less than 14 h was beneficial to diapause, while the daylength more than 14 h was beneficial to growth and diapause inhabitation at three different temperatures (17℃, 20℃,and 23℃). Short daylength had a cumulative effect on diapause induction. The diapause rate decreased with the increase of temperature in the daylength from 10 h to 14 h, and temperature had no effect on diapause induction in the daylength more than 14 h. The critical photoperiods of A. lucorum were 13 h 10 min∶10 h 50 min (L∶D), 12 h 58 min∶11 h 2 min (L∶D)and 12 h 51 min∶11 h 9 min (L∶D) at 17℃, 20℃ and 23℃, respectively. The critical daylength shortened with the increase of temperature. The results suggest that A. lucorum is a typical long-day insect, photoperiod is the main factor of diapause induction, temperature is the cofactor of diapause induction, and low temperature in autumn is beneficial to the diapause induction.
