Abstract
Cultivars of proso millet, Panicum miliaceum L., were tested for oviposition and feeding response to 5 insect pests of grains in Oklahoma. ‘Big Red’ showed good tolerance to light infestations of chinch bugs, Blissus leucopterus leucopterus (Say) while foxtail millet, Setaria italica (L.) Beauv., survived a heavy attack. Corn earworms, Heliothis zea (Boddie), and fall armyworms, Spodoptera frugiperda (J. E. Smith), oviposited readily on millet entries, but southwestern corn borers, Diatraea grandiosella (Dyar), did not. Corn earworm larvae preferred the cultivar ‘Dawn’, but fall armyworm showed no preference. Weight differentials were significant when fall armyworms were reared on the millets. Reaction to feeding by the yellow sugarcane aphid, Sipha flava (Forbes), showed that some entries had intermediate resistance.
