Encouraging progress is being made, however, in the search for and utilization of earworm-resistant strains of both field and sweet corn. We mentioned the protection of ears from earworms, weevils, and grain moths by tight husks that extend beyond the tip of the ear.

The fall armyworm and the corn earworm attack sweet corn as earworms. [...] Although they may sometimes eat through the husk to attack the side of the ear, most earworms feed on the silks and enter through the silk channel to attack the tip of the ear. The earworm population may be almost completely composed of corn earworms or of fall armyworms, or of a mixture of the two species.
