摘　　要：为有效测报和防治苹小卷叶蛾,采用性诱剂诱集的方法,观察苹果苹小卷叶蛾成虫的发生消长动态。结果表明,在陕西省礼泉县苹果苹小卷叶蛾1年发生3~4代,越冬代成虫在5月上中旬开始羽化,每年各代成虫发生时间有一定的差异,有世代重叠现象;在苹果树高度为1.0~2.0 m范围内的不同位置,通过性诱剂诱集到的成虫数量存在一些差异,其中在苹果树离地1.5 m处分布的成虫数量最多,在实际生产中采用性诱剂对苹小卷叶蛾成虫进行诱杀时,可根据实际操作方便及效果最大化的原则,尽量将诱捕器放置在苹果树离地接近1.5 m高度的位置,以便获得更好诱捕效果;成虫活动时间主要在4:00—8:00时段,其中在4:00—6:00时段活动更频繁、更活跃。To forecast and control Adoxophyes orana efficiently, the adult dynamics of A. orana in orchards were observed by the method of sex attractant trapping. The results showed that A. orana had 3-4 generations per year in orchards, and the overwintering moth began emerging in early to mid-May. Each generation adult occurrence time was different every year, with generation overlapping. The number of trapped moths had certain difference at 1.0-2.0 m height of the apple tree. The number of the moths at 1.5 m height was the most. When the sex attractant was applied for trapping moths, sex attractants should be arranged near 1.5 m height of the apple tree in order to get better trapping effect. The moths mainly acted in 4：00-8：00, and the activities were more frequent and active in 4：00-6：00.
