European corn borer

Definition

A crambid moth (Ostrinia nubilalis) native to Europe and invasive in North America, whose larvae tunnel through stems and ears of maize and other grain crops, causing significant agricultural damage. The species exemplifies a specialist herbivore that has expanded its host range following introduction to new continents.

Etymology

Named for its European origin and larval habit of boring into corn (maize) stems and ears.

Example

Larvae of the European corn borer feed internally on maize stalks, creating entry points for fungal pathogens such as Fusarium and reducing yield through both direct damage and secondary infection.

Synonyms

• European corn worm
• European high-flyer

Related Terms

• Ostrinia nubilalis
• Crambidae
• stem borer
• Asian corn borer
• host range expansion

Usage Notes

The common name refers specifically to Ostrinia nubilalis; distinguish from the Asian corn borer (Ostrinia furnacalis), a congeneric pest of similar morphology and ecology in East Asia. In Europe, the species originally infested millet and broom corn before adapting to maize. The term is sometimes abbreviated ECB in agricultural literature.
