摘要：

本文研究了温度和光周期对枣镰翅小卷蛾求偶行为及性信息素释放的影响,结果表明,越冬代枣镰翅小卷蛾雌蛾的求偶高峰期为暗期6.0~8.0h。温度越高,雌蛾开始求偶的时间越迟,求偶的持续时间也越短,求偶高峰期比在正常温度下明显推迟。温度为21℃时雌蛾产生的性信息量最高, 26℃时略低,而在31℃和16℃时雌蛾性信息素释放量仅为21℃时的1/5~1/4;雌蛾所释放的性信息素中顺、反异构体比例随温度的降低向顺式异构体增加的方向漂移,其变异系数均控制在10%以下。当把第2日龄的雌蛾从14L:10D光周期转移到连续黑暗下时,雌蛾表现的求偶行为和性信息素产生与14L:10D下相似,均表现出明显的节律;当转移到连续光照下时,求偶行为变得不活泼和不规则,而产生的性信息素量却等于或高于14L:10D光周期下所产生的性信息素量。

Abstract:

In this paper, the calling behaviour and the effects of environmental temperature and photoperiodic changes oncalling behaviour and sex pheromone release in Ancylis sativa Liu were investigated. The results showed that the females calling peak period of Ancylis sativa Liu was at 6.0~8.0 hours in scotophase. The higher the temperature was, the later females called, the shorter the calling behaviour lasted. The sex pheromone titre released by females at 31℃ or 16℃ was almost only 1/5~1/4 of that released by females at 21℃. Meanwhile, the E/Z was changed with the temperature, that is Z isomer increased while the temperature decreased from 31℃ to 16℃, as well as the C.V. was perfectly controlled under 10%. Virgin females shifted to continuous dark from 14L:10D as 2-day old adults showed similar temporal patterns of both calling and pheromone production to those of moths held continuously at 14L:10D. This result indicates that both events have a circadian periodicity. When moths were shifted to continuous light at day 2, calling became inactive and irregular, whereas pheromone titres were equal or higher than those of moths under 14L:10D.
