中文摘要：
粘虫Mythimna separata（Walker）是我国粮食作物上一种典型的季节性远距离迁飞危害的重大农业害虫，具有发生范围广，危害世代多、作物损失重以及危害历史长的特点。每年粘虫在我国东半部自南向北形成5个不同类型发生区，除可在南方越冬外，还可通过季节性远距离往返迁飞在不同发生区之间危害。对其越冬、迁飞种群动态的监测及危害调查是实现粘虫综合防控的前提。根据粘虫的生物学特性以及不同类型发生区的特点，本文发展了粘虫田间越冬、迁飞种群以及幼虫发生危害的调查和监测技术，为其综合治理提供理论支撑。
英文摘要：The oriental armyworm, Mythimna separata (Walker) is a major agricultural and typical seasonal, long-distance, migratory, multigenerational, insect pest of food crops with a broad distribution and a long history of causing severe crop losses inChina. This pest occurs annually in 5 different regions from the south to the north of easternChina. It can overwinter in southChinaand damage crops in different regions through seasonal, long-distance and multigenerational roundtrip migrations. Monitoring the overwintering and migratory population dynamics and investigating larval occurrence in the field is essential for the effective management or this pest. Based on the species’ biology and occurrence characteristics in different regions, we developed methods and technologies for the investigation and monitoring of overwintering and migrant populations and larval occurrence, which can provide theoretical support for the species’ integrated management.
