| 中文摘要: |
| 草地贪夜蛾Spodoptera frugiperda入侵我国以来,先后发现其为害玉米、水稻、甘蔗、花生等作物。2023年5月,在广东省惠州市惠阳区淡水路河道旁发现草地贪夜蛾为害美人蕉和芦竹,平均百株虫量分别为15.0头和13.1头,虫龄多为5~6龄,部分3~4龄。幼虫主要为害心叶,造成半透明天窗、排孔、缺刻等为害状,亦有未展开幼嫩叶片或花苞丛被咬断。本文介绍了草地贪夜蛾为害美人蕉和芦竹的情况,为该虫的种群监测以及在景观植物上的防控提供参考。 |

| Since fall armyworm, Spodoptera frugiperda, invaded China, it has been found to damage corn, rice, sugar cane, peanuts and other crops. In May 2023, the damaged plants of Canna indica and Arundo donax were observed by S.frugiperda along the sides of Danshui river in Huiyang district, Huizhou city, Guangdong province. It was found that the average number of larvae per 100 plants was 15.0 larvae and 13.1 larvae respectively. Moreover, most of larvae were in 5th to 6th instars, and some were 3rd to 4th instars. Fall armyworm larvae damaged the whorl leaves, causing damage such as translucent skylights, rows of holes, and gnawed, even the furled whorl leaves or flower buds might also be chewed off. This article introduced the damage to C.indica and A.donax by S.frugiperda, and provided a reference for the monitoring the population and control of the pest in landscape plants. |
