【摘要】 研究了枣粘虫(Ancylissativa)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60～80h,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33次,雌蛾平均交配159次.2日龄成虫从14L10D光周期转移到连续黑暗下时,表现的交配行为与14L10D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.更多还原

【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*X10D to continuous dark was similar to that at 14L*X10D,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.更多还原
