Soybean, Glycine max (L.), grown in Iowa and most of the north central region of the United States has not required regular insecticide usage. The soybean aphid (Aphis glycines Matsumura) causes yield losses from direct plant feeding and has been shown to transmit several plant viruses. In Iowa, soybean aphid can colonize soybean fields in June and has developed into outbreaks in July and August capable of reducing yields by nearly 25%.
