| 中文摘要: |
| 草地贪夜蛾Spodoptera frugiperda (J.E.Smith)是一种重要的世界性害虫, 目前已经侵入我国云南省。田间调查发现, 草地贪夜蛾与甜菜夜蛾S.exigua、斜纹夜蛾S.litura和黏虫Mythimna separata在玉米上往往混合发生, 且形态相近, 容易混淆。本文详细描述了草地贪夜蛾卵、幼虫、蛹和成虫的外部形态特征, 并比较了其与甜菜夜蛾、斜纹夜蛾和黏虫的幼虫和成虫的形态差异。本文为草地贪夜蛾的准确鉴别和田间调查提供依据, 并为草地贪夜蛾的精准测报奠定基础。 |
| 英文摘要: |
| The fall armyworm, Spodoptera frugiperda (J.E.Smith), is a major crop pest worldwide, which has invaded Yunnan Province, China. It was observed that S. frugiperda, S. exigua (Hübner), S. litura (Fabricius) and Mythimna separata (Walker) with similar injury characteristics and morphology often occur together on corn plants, and are generally confused during the field survey. In this study, the morphological characteristics of eggs, larvae, pupae and adults of S. frugiperda were described in detail, and the morphological differences in the larvae and adults of S. frugiperda, S. exigua, S. litura and M. separata were compared. This report will provide technical instructions for S. frugiperda identification and field investigation, as well as a basis for the accurate forecast of S. frugiperda. |
