枣粘虫交配行为生态学研究

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，

Mating behavioral ecology of Ancylis sativa adult

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 most adults, 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 1 hour, and remained low until 48 hours after mating.
