| 中文摘要: |
| 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1.0~2.0 m范围内,诱集到的成虫数量有一定差异,2.0 m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2.0 m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。 |
| 英文摘要: |
| In order to forecast and control Ancylis sativa Liu efficiently, the adult dynamics of A.sativa in jujube orchards were investigated by sex attractant trapping. The results showed that A.sativa had 3-4 generations per year in jujube orchards in Yanchuan County, Shaanxi Province, most had 3 generations, a few had 4 generations. The overwintering moth began emerging in the mid and late March, with generation overlapping. The number of trapped moths had some difference at 1.0-2.0 m height of the jujube tree, and the most at 2.0 m height. When the sex attractant was applied for trapping, sex attractants should been arranged at near 2.0 m height of the jujube tree for better trapping effect. The moths mainly acted at 20: 00-24: 00 and 4: 00-6: 00, more frequently and actively at 20: 00-22: 00 and 4: 00-6: 00 |
