Ein weiteres in den Vereinigten Staaten eingeschlepptes Schadinsekt, zu dessen 

 Bekämpfung neben mechanischen Maßnahmen, die sich bisher als wirksamstes 

 Vertilgungsmittel erwiesen haben, auch die biologische Methode herangezogen 

 wurde, ist der Maiszünsler („European com borer"), Pyrausta nubilalis Hb. 1 )
