| 摘 要： | 草地贪夜蛾于2019年1月入侵云南江城县，随后逐步向国内扩散传播，同时为害作物种类也陆续增多。1月份入侵德宏主要为害玉米，4月份为害甘蔗，至2019年9月11日，发现草地贪夜蛾和斜纹夜蛾幼虫混合发生为害生姜。本文介绍草地贪夜蛾幼虫的为害程度和生姜的受害症状。草地贪夜蛾为害株率及百株虫量分别为58.4%和42.2头，发生量比斜纹夜蛾高，形成田间相对优势种群。建议准确区分草地贪夜蛾和斜纹夜蛾的田间为害情况，有效提供预测预报信息。

| Abstract: | The fall armyworm, Spodoptera frugiperda (J. E. Smith), invaded in Yunnan province in January 2019. Since then, the pest has spread gradually into many provinces and in the meanwhile injured more crops in China. S.frugiperda mainly damaged maize in January, damaged sugarcane in April, and damaged ginger in Dehong prefecture on September 11, 2019, which occurred together with S.litura on ginger. The paper described the occurrence of S.frugiperda and damage symptoms on ginger. Since damage rate and larva amount per 100 plants of S. frugiperda were higher than those of S.litura, which were 58.4% and 42.2 individuals, respectively, S. frugiperda was relatively dominant population in ginger field. We suggest that damage of S. frugiperda and S. litura in ginger field should be distinguished to provide correct information for insect pest forecasting and prediction. |
