Technical Abstract: Fall armyworm, Spodoptera frugiperda, is a migratory noctuid species that attacks field and vegetable crops throughout the Americas. This species is composed of two host strains which differ in their host plant choice, and two geographic strains which overwinter in Texas or Florida. Female moths produce a pheromone blend that attracts males for mating, however it is not known if the blend differs between the host or geographic strains. The pheromone is commercially-produced by several companies, although the pheromone components and ratios are different. Trap studies in Florida, Georgia, Alabama, and Texas showed few differences in number of moths caught among lures, but the percent of corn strain and rice strain moths differed depending on the time of year of collections.
