摘要
[目的]明确红枣桃小食心虫发生规律。[方法]采用性诱剂诱捕的方法,研究红枣桃小食心虫成虫的发生消长动态。[结果]红枣桃小食心虫在陕西延川1a发生1~2代,其中大部分1a发生1代,个别的发生2代;越冬代成虫在6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,在运用性诱剂诱杀红枣桃小食心虫成虫时,应尽量将诱捕器放置在枣树近2.0 m高处,以达到更好的诱捕效果;成虫活动时间主要在20:00~24:00和0:00~4:00时间段,其中在0:00~2:00时段活动更频繁、更活跃。[结论]试验结果为有效测报和防治红枣桃小食心虫提供了理论依据。
Abstract
Objective] The aim was to determine the occurrence regularity of Carposina niponensis. [Method] By using sex attractant trap meth-od, the population dynamics of C. niponensis adults was observed. [Result] The results showed that C. niponensis had 1-2 generations per year in Yanchuan County, Shaanxi Province, most of these had 1 generation, a few had 2 generations. The overwintering moth began emerging in the mid and late June, with generation overlapping. The number of trapped moths had some difference at 1. 0-2. 0 m height of the jujube tree, the number of the moths at 2. 0 m height was the most. When the sex attractant was applied for trapping moths, sex attractants should be arranged near 2. 0 m height of the jujube tree in order to get better trapping effect. The moths mainly acted during 20:00-24:00 and 0:00-4:00 time, whose activities were more frequent and active during 0:00-2:00. [ Conclusion] The study provides theoretical basis for effective report and control of C. niponensis.
