Description
Summary:Farmers in the midwestern United States considering alternative crops to diversify their agricultural production, include grain amaranth, Amaranthus spp. among them. Little is known of the insect pests that a grower might encounter while producing the crop. Reported herein is a study of several insect pests and their response to feeding on amaranth. Insects tested were the tarnished plant bug (Lygus lineolaris Palisot de Beauvois), fall armyworm (Spodoptera frugiperda (J. E. Smith)), cabbage looper (Trichoplusia ni (Hübner)), European corn borer (Ostrinia nubilalis (Hübner)) corn earworm (Heliothis zea (Boddie)), and the cowpea aphid (Aphis craccavora Koch.). Results indicate that most of the pests, except the European corn borer, will feed differentially on the amaranth lines tested. This knowledge should be useful for breeding insect-resistant cultivars. Plant material was obtained from the amaranth collection held at the North Central Regional Plant Introduction Station, Ames, Iowa.
