摘要
为掌握草地贪夜蛾在江苏省的发生及为害情况,在开展系统监测和田间调查的基础上,对2019年草地贪夜蛾在江苏省的发生动态及玉米受害情况进行了总结。结果表明,2019年5月入侵江苏苏南地区后,逐步向北扩散,6—7月是其主要扩散期。2019年江苏省玉米受草地贪夜蛾为害面积约3 440.3 hm2。其中,夏玉米发生面积最大、占71.5%。总体为害程度轻,沿海地区发生重于其他地区,秋玉米发生重于春、夏玉米。
To understand the occurrence and damage of Spodopte ra frugiperda in Jiangsu Province, we summarized the occurrence situation of Spodoptera frugiperda and its damage to maize in 2019 by systematic monitoring and investigation across the province. The results showed that Spodoptera frugiperda invaded Yixing and Liyang in southern Jiangsu in late May, and spread northward from June to July. The occurrence area of Spodoptera frugiperda on maize in 2019 was about3 440 hm2, mainly on summer maize that accounting for 71.5% of the total. The overall damage was slight, and the occurrence in coastal areas was more severe than in other areas, and the occurrence on autumn maize was more serious than on spring and summer maize.
