Abstract The fall armyworm (FAW), Spodoptera frugiperda , is a destructive pest native to America and has recently become an invasive insect in China. Because of its rapid spread great risks China, understanding FAW genetic background pesticide resistance urgent essential develop effective management strategies. Here, we assembled chromosome-level genome male (SFynMstLFR) compared re-sequencing results the populations from America, Africa, Strain identification 163 individuals collected Africa China showed that both C R strains were found American populations, while only strain was Chinese African populations. Moreover, population genomics analysis have close relationship with significantly differentiation Taken together, FAWs invaded into most likely originated Africa. Comparative displayed cytochrome p450 gene family extremely expanded 425 members FAW, which 283 genes are specific FAW. Treatments twenty-three pesticides variant patterns transcriptome profiles, several detoxification such as AOX UGT GST specially responded pesticides. These findings will be useful developing strategies for other areas.
