Role of <i>Sesamia nonagrioides</i> and <i>Ostrinia nubilalis</i> as Vectors of <i>Fusarium</i> spp. and Contribution of Corn Borer-Resistant Bt Maize to Mycotoxin Reduction

Maize expressing Cry1Ab insecticidal toxin (Bt maize) is an effective method to control <i>Sesamia nonagrioides</i> and <i>Ostrinia nubilalis</i>, the most damaging corn borers of southern Europe. In this area, maize is prone to <i>Fusarium</i> infections, which c...
