Technical Abstract: Fall armyworm is a significant agricultural pest attacking corn, grasses, sugarcane and other crops. The species is composed of two morphologically identical host strains that differ physiologically and behaviorally. We examined wild populations in southern Florida to test the possibility that interstrain mating was occurring and if these hybrids exhibited habitat preferences. Samples of larvae and adults taken from corn and sugarcane fields showed that plant host biases associated with host strains were maintained.
