Description

The soybean aphid, Aphis glycines Matsumura (Homoptera: Aphididae) is a relatively new pest to Iowa soybean fields. Since being discovered in 2000, Iowa has experienced large populations (>1,000/plant) in three of the six years this pest has been in the state (Lang 2003, M. O'Neal unpublished data). In 2005, Iowa once again experienced damaging populations of soybean aphids. Yield reductions in excess of ten bushels per acre were experienced in university test plots across Iowa. This reduction in yield occurred in spite of lower populations than experienced in past years with large populations (Lang 2003, M. O'Neal unpublished). The 2005 growing season has illustrated the need for continued research on soybean aphid management in Iowa.
