Abstract

It was much sooner than I expected, but I knew eventually someone would find soybean aphids in western Iowa. Hal Tucker (Tucker Consulting, Storm Lake) reported on June 21 that he found soybean aphids near Correctionville in Woodbury County. Brian Lang, Iowa State University Extension field specialist-crops, continues to find small populations near Decorah and also has found them at Nashua on the Northeast Research and Demonstration Farm. Now we have to begin to think seriously about scouting for this insect.
