摘 要 ：通过在枣林中的系统调查与试验研究,明确了枣镰翅小卷蛾(Ancylis　safiva　Liu)成虫趋向其性信息素的行为及利用性信息素诱捕成虫的时辰节律;大面积诱杀对枣林中这种害虫种群的控制作用。应用性信息素引诱枣镰翅小卷蛾成虫有两个高峰期,第1个在4:00～6:00,其累计诱杀率为37%～76%,第2个在18:00～22:00,其累计诱杀率为15%左右。性信息素引诱不仅影响成虫的求偶及交配行为,同时也干扰了成虫的取食、扩散与隐蔽情况下的飞行活动。大面积枣林中诱杀防治试验结果表明,诱杀区与对照区比较,有效卵的减退率为685%～852%。

Abstract:By studying in detail in jujube forest, the behaviors of tending to sex pheromone on the adult Ancylis sativa Liu, the rhythm of trapping the males and the control of the pest by sex pheromone in jujube forest in a large acreage are understood. There are two trapping peaks: the first one is from 4:00 to 6∶00, trapping rate is from 37% to 76%; the second one is from 18:00 to 22:00; trapping rate is 15% or so. Sex pheromone can not only affect the courting and copulation of the adult Ancylis sativa Liu, but also disturb its flying behaviors in the course of feeding dispersal and concealment. A large acreage pheromone trap experiment indicates that the fertilized eggs of the pest are reduced from 68.5% to 85.2%.
