Abstract

Abstract: The fall armyworm, Spodoptera frugiperda (J. E. Smith), is a major global warning agricultural pests. In January 2019, the pest invaded into western Yunnan province and quickly spread to 21 provinces in China. During maize seedling stage in Henan province, S. frugiperda larvae occurred together with other lepidoptera pests, such as S. exigua, Helicoverpa armigera, Ostrinia furnacalis, and Mythimna loreyi. These insect larvae display similar damage symptoms and morphological characteristics. Consequently, accurate identification of the pest species is crucial for their monitoring and management. Here we provided the morphological differentiation of the young and mature larvaeof these pests, which is expected to technically support the accurate monitoring and forecast of S. frugiperda in maize field in Henan province.

Key words: Spodoptera frugiperda, maize seeding pests, larvae morphological characteristics
