摘　　要：草地贪夜蛾Spodoptera frugiperda(Smith)是一种重要的外来入侵新害虫,目前已入侵我国14个省区500多个县区,对我国玉米等种植业造成严重威胁,加强该虫的监测与防控显得尤为必要而紧迫。本文针对入侵我国的“玉米型”草地贪夜蛾,在成虫数量、田间虫情和作物受害程度3个方面提出了一套较为系统的调查监测方法,可为监测明确该虫入侵虫源、发生数量、危害程度及其动态,确定发生分布区域、预测预报发生期、发生程度等提供方法依据。The fall armyworm, Spodoptera frugiperda (Smith), is an important alien pest, and has invaded into more than 500 counties, 14 provinces in China's Mainland now. Because it would cause great threat to corn and other planting industries in China, it is even more necessary and urgent to carry out the monitoring and control of S. frugiperda . In this paper, the systematic methods of investigation and monitoring for S. frugiperda “corn strain”, with the adult population, occurrence in the field and damage rate, were presented. The methods would provide the basis not only for clearing the adult migration, population, damage and their dynamics, but also for determining the distribution region, and forecasting the occurrence period and degree, etc.
