Abstract

Host strains (corn and rice) of the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), were evaluated for oviposition preference, mating compatibility, and development on artificial diet and four plant species. Both strains oviposited a greater percentage of egg masses on corn (Zea mays L.), sorghum (Sorghum bicolor [L.] Moench.), and bermudagrass (Cynodon dactylon [L.] Pers.) than on centipedegrass (Eremochola ophiuroides [Munro] Hack). The corn strain oviposited preferentially on corn and sorghum, while the rice strain preferred bermudagrass. The number of fertile intrastrain and interstrain pairs ranged from 77 to 100%. Egg hatch was extremely high for all crosses (>80%). The F
