However, unexplained variation in the validation analysis was present, and misalignments between the simulated movement patterns of fall armyworm populations and the haplotype ratios at several locations, especially in the northeastern US and Canada, have been reported. Introduction: Biophysical approaches validated against haplotype and trap catch patterns have modeled the migratory trajectory of fall armyworms at a semi-continental scale, from their natal origins in Texas or Florida through much of the United States east of the Rocky Mountains. 3Retired, State College, PA, United States.Department of Agriculture- Agriculture Research Service- Center for Medical, Agricultural, and Veterinary Entomology (USDA-ARS CMAVE), Gainesville, FL, United States
