Fall armyworm [Spodoptera frugiperda (J. E. Smith)] is a major economic pest throughout the Western Hemisphere of maize, cotton, sorghum, and variety agricultural grasses vegetable crops. Previous studies demonstrated extensive annual migrations occurring as far north Canada from overwintering locations in southern Florida Texas. In contrast, migratory behavior rest hemisphere largely uncharacterized. Understanding migration patterns fall will facilitate efforts to predict spread pesticide resistance traits that repeatedly arise this species assess consequences changing climatic trends on infestation range. Four independent colonies derived widely separated populations Mexico two field collections were examined for their mitochondrial cytochrome oxidase I (COI) gene haplotypes compared with other locations. The most similar haplotype profile those Texas South America, but also displayed some distinctive features. data extend distribution map confirm previously observed regional differences frequencies are stable over time. associated rarely found elsewhere, suggesting limited interactions foreign populations, including neighboring
