Global population genomic signature of Spodoptera frugiperda (fall armyworm) supports complex introduction events across the Old World

Communications Biology, 2022
Native to the Americas, the invasive Spodoptera frugiperda (fall armyworm; FAW) was reported in West Africa in 2016, followed by its chronological detection across the Old World and the hypothesis of an eastward Asia expansion.
