美国白蛾(Hyphantria cunea Drury)是国际性检疫害虫,本研究连续4年通过野外观察以及性诱捕器诱捕准确掌握了美国白蛾在枣庄地区的生活史以及各代成虫发生高峰期具体时间。研究表明:美国白蛾在枣庄地区一年发生3代,3代成虫发生高峰期分别为4月29-5月3日、7月4-10日、8月13-21日。同时雨天等环境因素对美国白蛾发生规律影响较大,这为科学指导飞机防治提供理论支撑。
Hyphantria cunea Drury is an international quarantine pest. In this study, we observed the life history of the white moth in Zaozhuang area and the peak time of each generation via field observation and trapping by sexual traps. Studies have shown that: the United States white moth occurrence in Zaozhuang area three generations a year, the third generation of adults peaked at April 29 - May 3, July 4 -10, August 13-21. At the same time, environmental factors such as rainy days have a greater impact on the occurrence of the American white moth, which provides theoretical support for the scientific guidance of aircraft control.
