  abstract = {{T}he fall armyworm ({FAW}; {S}podoptera frugiperda) is one of the major agricultural pest insects. {FAW} is native to the {A}mericas, and its invasion was first reported in {W}est {A}frica in 2016. {T}hen it quickly spread through {A}frica, {A}sia, and {O}ceania, becoming one of the main threats to corn production. {W}e analyzed whole genome sequences of 177 {FAW} individuals from 12 locations on four continents to infer evolutionary processes of invasion. {P}rincipal component analysis from the {TPI} gene and whole genome sequences shows that invasive {FAW} populations originated from the corn strain. {A}ncestry coefficient and phylogenetic analyses from the nuclear genome indicate that invasive populations are derived from a single ancestry, distinct from native populations, while the mitochondrial phylogenetic tree supports the hypothesis of multiple introductions. {A}daptive evolution specific to invasive populations was observed in detoxification, chemosensory, and digestion genes. {W}e concluded that extant invasive {FAW} populations originated from the corn strain with potential contributions of adaptive evolution.},
