During 1988 and 1989, the relationship between different weed communities in corn plantings and infestation of and damage to corn by the stalk borer, Papaipema nebris (Guenée) (Lepidoptera: Noctuidae), was studied in Ohio. The four treatments were corn without weeds, corn principally with broadleaf weeds, corn principally with grasses, and corn with a mixture of both weed types. In 1988, there were no significant differences between treatments with broadleaf weeds and treatments without broadleaf weeds, and between treatments with grassy weeds and treatments without grassy weeds, in terms of number of larvae per corn plant and number of corn plants damaged. Low populations of P. nebris in corn during 1988 may have been associated with severe drought which caused low larval survival. There were significantly more larvae per corn plant and a significantly greater percentage of corn plants damaged in plantings containing broadleaf weeds than in corn plantings without broadleaf weeds in 1989. The results of this study show that the presence of broadleaf weeds in corn fields may lead to increased infestation of corn by stalk borer larvae.
