摘　　要：The fall armyworm(Spodoptera frugiperda)is one of the major pest insects damaging diverse crops including cotton,corn,rice,and sorghum.Fall armyworms have been identified as two morphologically indistinguishable strains,the corn strain,and the rice strain,named after their preferred host-plants.Although initially recognized as hostplant strains,there has been an ongoing debate regarding whether the corn and rice strains should be considered as such.In this article,we present arguments based on recent population genomics studies supporting that these two strains should be considered to be host-plant strains.Furthermore,host-plant adaptation appears to be a driving evolutionary force responsible for incipient speciation in the fall armyworm.
