Bagging ears of a dent corn hybrid in the field was effective in reducing damage by naturally occurring populations of Lepidoptera, but was not effective in reducing the production of aflatoxin on the ear. Insects produced conditions in the infested ear that were conducive to aflatoxin production and insect species differed in their relationship to increased aflatoxin production. Ears infested with European corn borer, Ostrinia nubilalis (Hübner), had the highest concentrations of aflatoxin B1.
