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.

Description: 

We discuss the likelihood that aphid outbreaks will occur and when to spray aphid populations. Some agri-businesses are suggesting that aphids be sprayed when populations are lower than 250 aphids per plant. We discuss the value of such lower thresholds, as well as ways to detect other invasive insect pests of soybeans.
