Fourteen species of Arachis were evaluated for survival, leaf consumption, development rate, and preference by the fall armyworm, Spodoptera frugiperda (J. E. Smith). Using a host-suitability index, A. monticola, A. hypogaea, cv. 'Florunner', A. stenosperma, and A. batizogaea were the most suitable hosts and were classified susceptible to the fall armyworm. A. burkartii and A. villosa were the least suitable hosts and were classified resistant. These classifications were also supported, in general, by preference of the insect for the species of Arachis.
