Abstract

Field corn, Zea mays L., is a commonly grown crop in Mississippi. Brown stink bug, Euschistus servus Say, is an insect that can infest field corn. Growers and consultants have expressed concerns of the difficulty in detecting infestations and estimating yield loss potential once damage is found in a field. The results of these experiments showed a relationship between damage severity, plant height, and yield loss. As damage severity increased, plant height and yield were significantly reduced. On a per area basis, yields were reduced when ≥ 10% plants were damaged. Mean plant heights were reduced when ≥ 20% plants were damaged. Results from simulated damage experiments were similar to those of the natural infestation damage; however, target damage severities (damage ratings) were not achieved. Further methodology refinement is needed.
