Abstract:Results of field studies during the summer of 1973, 1974, and 1978 indicated that sampling the population European corn borer moths (ECB), Ostrinia nubilalis (Hübner), in dense vegetation (action sites), predominately giant and green foxtailgrass, Setaria faberi Herrm. and S. viridis (L.) Beauv., respectively, could predict the potential 2nd-generation ECB populations in adjacent corn fields. Numbers of ECB egg masses on corn plants were highly correlated (r = 0.94, 1973; r = 0.91, 1974; r = 0.92, 1978) with numbers of female ECB moths/1-m2 (min of 20, one-m2 samples/sample date) in dense grass in waterways and near borders of corn fields. Treatment of these areas bordering corn fields with 2.26 kg AI/ha carbaryl killed ECB moths, significantly reduced numbers of egg masses deposited per plant in the corn fields (untreated borders, 3.3 egg masses/corn plant; treated borders, 0.2 egg masses/corn plant), significantly reduced ECB cavities per plant (untreated borders, 40.8 cm; treated borders, 14.3 cm), and significantly increased grain yield per plant (untreated borders, 192.1 g; treated borders, 210.0 g). A regression equation, based on numbers of female ECB moths per 1-m2 of action site was developed for predicting potential 2nd-generation ECB populations in corn fields.
