European corn borer, European corn worm, European high-flyer
The European corn borer is a non-native moth pest of corn and other crops in North America, Europe, and North Africa. Larvae bore into corn plants, causing damage to stems, ears, and leaves. Two pheromone strains exist: the Z strain (prevalent in the midwestern U.S.) and the E strain (more abundant in the eastern U.S. and Europe). Widespread adoption of Bt corn since 1996 has dramatically reduced populations in North America, with over 90% suppression reported in some regions.
