摘要 迁飞害虫因其突发性、暴发性和异地虫源等特点常造成农作物损失。2020年农业农村部公布的国家一类农作物病虫害名录上10种（类）害虫中就有8种（类）是迁飞性害虫。本文回顾了李光博院士在我国黏虫越冬迁飞规律与行为机制研究中的杰出贡献，包括：带领全国越冬调查协作组，首次提出我国黏虫越冬区划;首创黏虫大规模“标记-释放-回收”试验，揭示了季节性远距离南北往返迁飞规律;开启黏虫迁飞行为机制研究先河，发现黏虫迁飞与生殖生活史适应特征。李先生对黏虫越冬迁飞规律与机制的研究在国内外产生了重要影响，引领国内外其他迁飞害虫研究与治理，为迁飞害虫的监测预警和综合治理提供了理论依据并做出了重大贡献。结合李光博院士的研究成果，简要介绍了现阶段我国主要迁飞害虫的研究进展，并对未来研究趋势做了展望。

Abstract Migratory insect pests usually cause crop losses due to their characteristics of sudden and explosive occurrence and exotic population source. In 2020， 8 out of 10 species （category） on the National List of Crop Diseases and Insect Pests announced by the Ministry of Agriculture and Rural Affairs were migratory pests. This paper reviewed Academician Li Guangbos outstanding contributions to the research on the overwintering， migration regularity and behavioral mechanisms of the oriental armyworm， Mythimna separata （Walker）. He proposed overwintering region division of M.separata in China for the first time by leading the national overwintering investigation cooperative group， and unveiled M.separata seasonal， long-distance， multigenerational roundtrip migration between southern and northern China by originating the large-scale mark-release-recapture experiment. Furthermore， he led the way in opening the study on regulation of migration behavior mechanism of M.separata， and found the adaptive characteristics between migration and reproduction. Academician Li Guangbos research on the overwintering， migration regularity and behavior mechanism of M.separata had great impacts at home and abroad， made significant contributions by leading the similar research and management of other migratory pests， and provided theoretical basis for monitoring， forecasting and integrated management of migratory pests. Based on the research achievements of Academician Li Guangbo， we introduced the present research progress of major migratory pests in China in brief， and presented their future research tendency as well.

害虫迁飞是在长期适应多变的环境过程中进化形成的一种行为对策，也是通常造成害虫大面积和多世代暴发致灾的重要原因。我国地跨热带、亚热带、温带和寒温带等多个季风气候带，给迁飞害虫发生为害提供了适宜的时空条件，有利于迁飞害虫在我国季节性南北往返迁飞为害。长期以来，飞蝗Locusta migratoria、黏虫Mythimna separata、草地螟Loxostege sticticalis、稻飞虱、稻纵卷叶螟Cnaphalocrocis medinalis等一直都是我国农作物主要迁飞害虫，给我国农业生产和粮食安全带来严重威脅。……
