Description: 

Drs. O'Neal and Hodgson summarize reports from around the midwest and Iowa about the soybean aphid. Despite the lack of aphids in the fall, evidence so far is that they survived and are beginning to build up in the northern parts of Iowa. Numbers are still very low and do not require insecticides, but we compare 2011 to previous growing season.
