摘　　要：为有效监测和防治枣镰翅小卷蛾,采用性诱剂诱捕的方法,观察了枣镰翅小卷蛾成虫的发生消长动态。结果表明,枣镰翅小卷蛾在陕西延川1年发生3～4代,其中以1年发生3代为主,个别的发生4代;越冬代成虫在3月中下旬开始羽化;有世代重叠现象;在枣树高度1.0～2.0m范围内,诱集到的成虫数量有一定差异,2.0m处分布最多,在运用性诱剂诱杀枣镰翅小卷蛾成虫时,应尽量将诱集器在枣树高度近2.0m处,以达到更好的诱捕效果;成虫活动时间主要在20：00-24：00及4：00-6：00时间段,其中在20：00-22：00及4：00-6：00时段活动更频繁、更活跃。In order to forecast and control AncylissativaLiu efficiently,the adult dynamics of A.sativain jujube orchards were investigated by sex attractant trapping.The results showed that A.sativa had3-4 generations per year in jujube orchards in Yanchuan County,Shaanxi Province,most had3 generations,a few had4 generations.The overwintering moth began emerging in the mid and late March,with generation overlapping.The number of trapped moths had some difference at 1.0-2.0m height of the jujube tree,and the most at 2.0m height.When the sex attractant was applied for trapping,sex attractants should been arranged at near 2.0m height of the jujube tree for better trapping effect.The moths mainly acted at 20：00-24：00and4：00-6：00,more frequently and actively at 20：00-22：00and 4：00-6：00.
