Developmental biology and food consumption and utilization of male and female southwestern corn borers, Diatraea grandiosella Dyar, and fall armyworms, Spodoptera frugiperda (J. E. Smith), were compared when reared on a meridic diet. Variations in so

Two single-cross corn, Zea mays L., hybrids (Mp701 × Mp706 and Mp496 × Mp707) with leaf-feeding resistance at the midwhorl stage of growth to fall armyworm, Spodoptera frugiperda (J. E. Smith), were evaluated for resistance from seedling (V3) to pr

Field cage experiments were done to determine if maize ( Zea mays L.) hybrids with leaf-feeding resistance to larvae of southwestern corn borer, Diatraea grandiosella Dyar, and fall armyworm, Spodoptera frugiperda (J. E. Smith), also are less preferr

A comparative study of the fall armyworm, Spodoptera frugiperda (J. E. Smith), reared on leaf-feeding resistant and susceptible corn genotypes was conducted in the field and laboratory in 1983 to determine the effects of resistance on survival, growt
