摘要: 为掌握桃小食心虫的活动规律、有效测报及防治提供理论依据,采用性诱剂诱集的研究方法,研究苹果桃小食心虫的发生规律。结果表明:苹果桃小食心虫1 年发生2~3 代,成虫发生量最高峰发生在7 月20 日,有世代重叠现象;桃小食心虫成虫在苹果树上1.0~2.0 m处的分布无显著差异,在运用性诱剂诱杀桃小食心虫成虫时,可根据操作方便的原则,在苹果树1.0~2.0 m处随意设置性诱剂,不会影响诱集效果;成虫主要在22:00 以后,至清晨6:00 时间段活动,其中在0:00—2:00 时间段活动最频繁、最活跃。试验更进一步了解了桃小食心虫的发生规律,为更有效地防治提供参考。

Abstract: In order to master activities of Carposina niponensis and provide theoretical basis for effective forecast and prevention, the occurrence of Carposina niponensis in orchards were studied by the method of sex attractant trapping. The results showed that Carposina niponensis had 2 or 3 generations per year in orchards, the amount of adult peak occurred in July 20th, with generation overlapping. The distribution of adults had no significant difference at 1.0-2.0 m height of the apple tree. In the application of sex attractant for the adults, according to the principle of easy to operate, sex attractants were randomly arranged at 1.0-2.0 m height of the apple tree, but it did not affect the trapping effect. The adults mainly acted in 22:00 to 6:00 of the next morning, whose activities were the most frequent and active in 0:00 to 2:00. The occurrence of Carposina niponensis in orchards were further understood to provide theoretical basis for more effective treatment.
