Invasive species pose a major threat to global biodiversity and agricultural productivity, yet the genomic mechanisms driving their rapid expansion into new habitats are not fully understood. The fall armyworm, Spodoptera frugiperda, originally from the Americas, has expanded its reach across the Old World, causing substantial reduction in crop yield. Although the hybridization between two genetically distinct strains has been well-documented, the role of such hybridization in enhancing the species’ invasive capabilities remains largely unexplored.

群体基因组学分析揭示了杂交在草地贪夜蛾快速入侵中的作用


入侵物种对全球生物多样性和农业生产力构成重大威胁，但驱动它们迅速扩展到新栖息地的基因组机制尚不完全清楚。草地贪夜蛾（Spodoptera frugiperda）最初来自美洲，现已扩展到整个旧世界，导致农作物产量大幅下降。尽管两种遗传不同的菌株之间的杂交已经有据可查，但这种杂交在增强物种入侵能力方面的作用在很大程度上仍未得到探索。
