| 2019年秋季调查了河南省新乡市草地贪夜蛾在不同作物上的发生和为害情况。首次发现草地贪夜蛾幼虫严重为害白菜, 同时其还在夏玉米、甘蓝、秋高粱和秋玉米上为害。草地贪夜蛾幼虫种群数量于9月初在夏玉米、白菜和甘蓝上达到高峰, 9月中旬在秋高粱和秋玉米上达到高峰, 在夏玉米、白菜、甘蓝、秋高粱和秋玉米上高峰期时百株虫量分别为3、24、20、40头和88头。采用探照灯诱集草地贪夜蛾成虫, 发现秋季成虫高峰期在9月13日, 当日诱集蛾量达95头, 且成虫上灯一直持续至11月中旬。最后对2019年秋季草地贪夜蛾幼虫和成虫的发生为害规律进行了讨论, 以期为2020年草地贪夜蛾的预测预报和防控提供依据。 |
