摘要:
目的 明确草地贪夜蛾在福建省的入侵动态及应急药剂防治技术。 方法 通过田间实地调查，开展福建省玉米草地贪夜蛾发生与为害监测；利用茎叶喷雾法开展杀虫剂田间药效试验评价。 结果 2019年5月6日，福建省首次发现草地贪夜蛾在玉米上发生为害，随后全省多地陆续发现草地贪夜蛾侵入为害，截至11月4日，草地贪夜蛾在福建省的寄主范围仅限于为害玉米，共有53个县（市、区）发生草地贪夜蛾，累计发生面积达646.23 hm2；药效试验结果表明，氯虫苯甲酰胺、茚虫威、乙基多杀菌素、虫螨腈、甲氨基阿维菌素苯甲酸盐、高效氯氟氰菊酯对草地贪夜蛾具有良好的田间防效，药后3 d、10 d的防效分别为88.08%～91.46%和91.41%～94.01%，可以有效控制草地贪夜蛾的发生为害。 结论 草地贪夜蛾已侵入福建省并在玉米上发生为害；氯虫苯甲酰胺、茚虫威、乙基多杀菌素、虫螨腈、甲氨基阿维菌素苯甲酸盐、高效氯氟氰菊酯等6种杀虫剂可作为草地贪夜蛾应急防治的理想药剂。 Abstract:Objective Real-time continuous monitoring on the invasion of fall armyworms (Spodoptera frugiperda) and the insecticide control efficacy in corn fields in Fujian. Method Based on field surveys, a program was designed to continuously monitor the pest invasion and the efficacies of various insecticides. Selected insecticides were sprayed on the stems and leaves of corn plants in the field for the evaluation. Result Fall armyworm infestation was first reported on corn plants in the province on May 6, 2019. Then it spread to many areas, and by November 4, although only corn crops were affected, the disease had affected 53 counties with a total of 646.23 hectares of corn field. The insecticides, including chlorantraniliprole, indoxair conditioningarb, spinetoram, chlorfenapyr, emamectin benzoate, and lambda-cyhalothrin, were tested in the field and found effective in controlling further spread. After application, these agents displayed an efficacy between 88.08% and 91.46% in 3 d, and between 91.41% and 94.01% in 10 d. Conclusion Fall armyworms damaged the corn crops in the province and could currently be controlled by using insecticides as tested. -

1-3 instar larvae嫩叶 啃食鲜嫩叶片叶肉 被啃食部位仅留下表皮呈现半透明薄膜“窗孔”、薄膜破裂后呈不规则长条形不规则缺刻（图1-A） 4-6龄幼虫
4-6 instar larvae心叶 钻蛀咬食为害心叶 钻蛀咬食卷曲心叶和茎杆顶端幼嫩部分，形成钻蛀虫孔和不规则虫道，剥开卷曲心叶可见被咬食部位呈破烂状，并残留大量褐绿色粪便，玉米幼苗期生长点被咬食会造成植株枯死，被蛀食的心叶展开后呈现大型不规则的缺刻或孔洞（图1-B、图1-C） 雄穗 钻蛀咬食雄穗 抽雄初期从顶部或雄穗幼嫩苞叶钻蛀进入咬食花穗，苞叶展开后呈不规则的缺刻孔洞，被咬食花穗形成不规则咬食虫道并残留有大量褐绿色粪便（图1-D） 果穗 钻蛀咬食果穗 抽雄后幼虫转移钻进入果穗顶部玉米须取食然后钻蛀进入果穗咬食果粒，并残留大量褐绿色粪便（图1-F）
