Soybean aphids hatching on buckthorn

Reports from my colleagues around the Midwest indicate that soybean aphids are hatching on buckthorn. Bob O\u27Neil, Purdue University, is working with aphids in Illinois and noted the first hatch occurred on March 27. Chris DiFonzo, Michigan State University, found newly-hatched aphids in central Michigan on April 17. To the west of us, Tom Hunt, University of Nebraska, found soybean aphids on buckthorn in Lincoln on April 23
