为了探讨温度和光周期对绿盲蝽Apolygus lucorumMeyer-Dr越冬卵滞育解除和发育历期的影响,系统调查了绿盲蝽越冬卵在不同温度和不同光照组合下的孵化率和孵化时间,结果显示:绿盲蝽的越冬卵均为滞育卵,低温和光周期对绿盲蝽越冬卵的滞育解除均有影响。2℃的低温处理能够显著促进其滞育解除,在0~65d范围内,随着低温处理时间增长,其滞育解除时间缩短,未经低温处理的越冬卵T50为68.5d,低温处理65d的T50为12.25d,绿盲蝽越冬卵在2℃低温处理65d后完全解除滞育;在0~40d范围内,低温处理时间越长,绿盲蝽越冬卵的孵化率越高,在25℃、全光照的条件下不经低温处理的孵化率为68.65%,低温处理40d后在25℃的条件下的孵化率达到99.46%。在20~26℃范围内,绿盲蝽越冬卵的滞育后发育历期随着温度的上升而缩短,随着光周期的延长而缩短。结果说明低温处理能够提高绿盲蝽越冬卵滞育解除率,但不是其滞育解除的必要条件,低温处理与自然变温对绿盲蝽滞育解除的作用相似;高温和长光照能够促进绿盲蝽的滞育解除,缩短发育历期。
To investigate the effects of temperature and photoperiod on the diapause termination and developmental duration of overwintering eggs of Apolygus lucorum Meyer-Dr, the hatchability and incubation time of overwintering eggs of Lygus were studied systematically under different light and light regimes. The results showed that the overwintering eggs of Apolygus lucorum were all diapause eggs, and the effects of hypothermia and photoperiod on the diapause termination of overwintering eggs of Apolygus. 2 ℃ low temperature treatment can significantly promote the diapause release, in the 0 ~ 65d range, with the increase of low temperature treatment time, diapause termination time shortened, no cold treatment of overwintering eggs T50 68.5d, low temperature treatment 65d T50 was 12.25 days. The overwintering eggs of M. lucorcell were completely released from diapause after 65 days of low temperature treatment at 2 ℃. The hatching rate of overwintering eggs of O. lucorvis increased at 0-40 days, Under the condition of full illumination, the hatching rate was 68.65% without low temperature treatment, and after 40 days of low temperature treatment, the hatching rate reached 99.46% under the condition of 25 ℃. In the range of 20 ~ 26 ℃, the developmental duration of diapause of overwintering eggs of N. lizards shortens with the increase of temperature and shortens with the extension of photoperiod. The results showed that low temperature treatment could improve the diapause overwintering eggs, but it was not the necessary condition for its diapause termination. The effects of low temperature treatment and natural temperature change on diapause termination were similar. High temperature and long light could promote green blindness Stagnant diapause lift, shorten the developmental history.
