摘　　要：草地贪夜蛾是近年入侵我国的重大农业害虫,对云南农业产业的威胁尤其严重,研究其在云南不同发生区的为害特点对指导开展跨区域统防统治意义重大。笔者对2020年云南省草地贪夜蛾在周年发生区和季节性发生区的发生情况进行了调查,结果表明:周年发生区内,普洱、西双版纳的成虫诱集量最多,且均在5—6月出现蛾峰,田间幼虫虫峰紧随其后,出现在5—7月,且为害在各监测点中也最严重;季节性发生区的草地贪夜蛾成虫诱集量及田间幼虫发生量普遍小于周年发生区。性诱监测结果表明,有效成分比例顺-9-十四碳烯乙酸酯∶顺-11-十六碳烯乙酸酯∶顺-7-十二碳烯乙酸酯=79∶20∶1的诱芯对草地贪夜蛾成虫的诱集效果较好。The fall armyworm(FAW), Spodoptera frugiperda, is a destructive invasive agricultural pest in China, and is posing a serious threat to agricultural production in Yunnan. It is of great significance to study its damage characteristics in different areas in Yunnan to guide the development of inter-regional pest management strategies. In this study, the yearround breeding and seasonal occurrence areas of FAW were investigated in 2020. The results showed that the total number of trapped moths in Pu′er and Xishuangbanna was the largest, and the catches peaked from May to June. The population of FAW larvae in the maize field at Pu′er and Xishuangbanna sites peaked from June to July, and the damage was more serious than in other monitoring sites. The number of adults and larvae in the seasonal occurrence areas was generally less than that in the year-round breeding areas. The results showed that the lure with pheromone component of(Z)-9-tetradecenyl acetate:(Z)-11-Hexadecenyl acetate:(Z)-7-dodecenyl acetate=79∶20∶1 attracted more adults of S. frugiperda.
