摘要: 研究了枣粘虫(Ancylis sativa)成虫交配行为生态学.结果表明,越冬代成虫的交配高峰期为暗期6.0~8.0h,交配活动以羽化后2~3d表现强烈.环境温度越高,成虫开始交配的时间越迟.成虫交配持续时间多为3~4h,雌雄蛾均有多次交配习性,雄蛾平均交配3.3次,雌蛾平均交配1.59次.2日龄成虫从14L◇10D光周期转移到连续黑暗下时,表现的交配行为与14L◇10D下相似,均表现明显的节律,转移到连续光照下时,交配行为变得不活泼和不规则.处女雌蛾交配后1h,其性信息素滴度显著降低,48h未见恢复.

Abstract: The study shows that the mating peak of the overwintering generation adults of Ancylis sativa appeared at 6.0~8.0 hours in their scotophase and the mating activity was more intensive during 2~3 days after eclosion.The higher the temperature was, the later the adults began to mate.For mostadults, the duration of mating was 3~4 hours,with a mean frequency of 3.3 times for males and 1.59 for females.The mating behavior of 2-days old adults shifted from photoperiod 14L◇10D to continuous dark was similar to that at 14L◇10D,all showing an obvious rhythm.When the adults were shifted to continuous light,their mating became inacitive and irregular.The sex pheromone titer of virgin female decreased significantly after mating l hour,and remained low until 48 hours after mating.
