Earworms are a constant threat to producing corn seed in Hawaii. The earworms emerge from eggs laid on the corn silk; as many as 20 or more eggs can be desposited on a single ear. Entering the corn at its tip, the earworms feed on the kernels as the ear develops its seed. If left unchecked, the damage is devastating. HCIA, Mark Wright and University of Hawaii's Department of Plant and Environmental Protection Sciences at the College of Tropical Agriculture and Human Resources have agreed that endemic and naturalized wasp species that currently exist in Hawaii are an effective means of control.
