To assess fall armyworm migration behavior and how it affects the distribution of Bt-resistance traits that are being found in fall armyworm populations that overwinter in southern Florida.
The distribution pattern of Bt-resistance in southern Florida will be mapped by bioassays of field-collected specimens from selected overwintering locations. The resistance trait will be correlated with genetic markers currently being used to identify fall armyworm subpopulations and to define migratory boundaries. These data will be compared to the genetic markers and resistance trait distribution found in migratory populations. From these comparisons, the likely migratory pathways from southern Florida will be extrapolated and used to verify and improve existing pest migration models.
