AbstractCorn, Zea mays L., is the most abundant field crop in Iowa, and there are many insect pests associated with this field crop. Although aphids are not typically economically important in corn, recent observations have indicated several aphid species developing heavy populations in northwest Iowa and southwest Minnesota. Historically, the corn leaf aphid, Rhopalosiphum maidis (Hemiptera: Aphididae), has been the most abundant aphid species in corn. However, the bird cherry oat aphid, R. padi (Hemiptera: Aphididae) and several other species also have been detected. Recent observations show a shift to populations peaking later in the summer. Damage to potential and management guidelines for aphids in corn are not well defined and this research is aimed at developing economic threshold and sampling protocols.
