520			_aThe 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.
