The Iowa State University Integrated Crop Management Conference is Iowa's premier crop production education event. No other program in Iowa brings together the diverse range of topics, slate of expert presenters and results of the latest University research.
The ICM Conference offers workshops focusing on the latest in crop production technology. Experts from Iowa and surrounding states will provide research updates and results in soil fertility, soil and water management, crop production and pest management.

Abstract
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1,000/plant) in three of the six years this pest has been in the state (Lang 2003, M. O'Neal unpublished data).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occurred in spite of lower populations than experienced in past years with large populations (Lang 2003, M. O'Neal unpublished).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.
