Food utilization by larvae of the fall armyworm (Spodoptera frugiperda [J. E. Smith]) (Lepidoptera: Noctuidae), showed greater consumption of corn (Zea mays L.) than pinto bean diet, ‘Tifton 10', or ‘Coastal' bermudagrass (Cynodon dactylon [L.] Pers.). Transfer of larvae from diet to susceptible grasses such as corn, ‘Tifton 10' or ‘Coastal' produced differences in growth rates as a result of food consumption rates. Transfer of larvae from diet to resistant grasses such as ‘common' centipedegrass (Eremochola ophiuroides [Munro] Hack) ‘Tifton 292' bermudagrass, and zoysiagrass (Zoysia sp.) reduced larval growth as a result of low consumption rates and/or greater metabolic expenditures. Larvae initially fed ‘Tifton 10', ‘Coastal', or centipedegrass before feeding on corn grew significantly faster than when they fed continuously on corn.
