Migration is a widespread phenomenon among many insect species, including herbivorous crop pests. At present, scant information exists on the long-range migration of the polyphagous armyworm, Spodoptera exigua and its underlying climatic determinants (i.e. East Asian or South Asian monsoon circulation). In this study, we employed a population genetics approach to delineate S. exigua migration patterns across multiple Asian countries.

种群遗传学揭示了夜蛾的大规模迁移动态和种群周转

迁徙是许多昆虫物种的普遍现象，包括食草作物害虫。目前，关于多食粘虫、Spodoptera exigua的远距离迁徙及其潜在气候决定因素（即东亚或南亚季风环流）的信息很少。在这项研究中，我们采用群体遗传学方法来描述S. exigua在多个亚洲国家的迁移模式。
