Interpretive Summary:

Technical Abstract: The European corn borer (ECB), Ostrinia nubilalis (Hubner), is a primary economic pest of maize, Zea mays (L.), in the United States. It was introduced into this country from Europe prior to 1917 when it was first described as a maize pest. Host-plant resistance studies began in the United States during the 1920s. Considerable progress in developing maize cultivars with first generation ECB resistance was made by the 1950s when several inbreds with resistance to first-generation ECB were available. Due to lack of domestic resistant germplasm and the intensive labor required for identification of second generation ECB resistance, few resistant cultivars were identified. However, with more emphasis placed on second-generation ECB resistance, it has been successfully identified by Missouri and Iowa scientists and levels enhanced by recurrent selection. In Missouri, germplasms Mo-2ECB and Mo-2ECB-2 and inbreds Mo45, Mo46, and Mo47 have been released as sources of resistance to both generations of ECB.
