Population genomics analyses reveal the role of hybridization in the rapid invasion of fall armyworm.

Abstract excerpt

INTRODUCTION: 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...
