Since its discovery in North America in 2000, the soybean aphid has become the key insect pest of soybean in the north-central states and Canada. Populations of this insect have reached relatively widespread outbreak proportions during odd-numbered years, with localized outbreaks occurring with regularity. Widespread outbreaks in 2003 and 2005 cost soybean producers millions of dollars in management costs and lost yields. Captures of winged soybean aphids in suction traps in the Midwest in 2006 suggest the potential for a widespread soybean aphid outbreak in 2007.
