Billbugs
injure corn two different ways. First, the adult weevils chew small holes into
the stalk of seedling plants where they eat the tender leaves in the center.
When the leaves emerge, they often wilt and are riddled with transverse rows of
circular or linear holes. Plants may be killed. Those that live are stunted and
deformed, often with twisted leaves and numerous tillers or suckers around the
base of the stalk. Second, billbug larvae will tunnel in the base of the stalk,
causing further stunting of the plant.
