| 摘 要： | 草地贪夜蛾Spodoptera frugiperda(J.E.Smith)是我国重要的外来入侵害虫,2019年8月22日于江苏北部东辛农场发现草地贪夜蛾为害玉米,9月26日水稻田间零星见虫,10月22日在早播小麦上初次发现草地贪夜蛾造成危害,小麦被害率达52.60%,百株虫量20.4头。进一步研究发现5.7%甲维盐WG防治草地贪夜蛾药后7 d防效达96.45%,表现较好,可用于麦田草地贪夜蛾的防治。根据当前草地贪夜蛾为害小麦的严峻形势,我们必须加强对麦田草地贪夜蛾的监测与防控。

| Abstract: | Fall armyworm, Spodoptera frugiperda (J.E.Smith), is an important alien invader in China. It was found caused damage to corn in the Dongxin farm in northern Jiangsu province on August 22, 2019, and occasionally occurred in rice field on September 26. On October 22, the fall armyworm was found caused damage to the early-sown wheat for the first time. The damage rate of wheat was 52.60%, and there were 20.4 larvae per 100 plants. Further study showed that emamectin benzoate 5.7% WG had a high control effect of 96.45% seven days after spraying. Under the current severe situations, the monitoring and control of S. frugiperda in wheat field should be strengthened. |
