| 中文摘要: |
| 草地贪夜蛾 Spodoptera frugiperda (J. E. Smith)是全球预警的一种重大迁飞性农业害虫。2019年1月入侵我国,目前已扩散蔓延至我国24个省份。田间调查发现,在玉米灌浆期,草地贪夜蛾与黏虫 Mythimna separata (Walker)、劳氏黏虫 Leucania loreyi (Duponchel)和棉铃虫 Helicoverpa armigera (Hübner) 等夜蛾科害虫常常混合发生,且形态相近,容易混淆,给调查和测报工作带来很大困难。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,比较了其与黏虫、劳氏黏虫和棉铃虫4个虫态在形态特征上的差别,以期为玉米灌浆期草地贪夜蛾的准确鉴别和田间调查提供依据,并为其精准测报奠定基础。 |
| 英文摘要: |
| The fall armyworm, Spodoptera frugiperda (J. E. Smith), is a major migratory global warning agricultural pest. Since January 2019, it has invaded the western part of Yunnan province and quickly spread to 24 provinces in China. The investigation of pests at corn filling stage in Henan province showed that the larvae of S. frugiperda were often occurred synchronously with other three common noctuidae pests, including Mythimna separata (Walker), Leucania loreyi (Duponchel) and Helicoverpa armigera (Hübner). These insect pests often display similar damage symptoms on maize and similar morphological characteristics. The accurate identification of these pests is very important for the forecast of their population dynamics. Thus, the morphological characteristics of eggs, larvae, pupae and adults of S. frugiperda were described in detail and compared with those of M. separata, L. loreyi and H.armigera . This report will provide technical instructions for S. frugiperda identification and field investigation at maize filling stage, as well as a basis for the accurate forecast of S. frugiperda. |
