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