With soybean harvest progressing rapidly across Iowa, growers are studying yields and discussing whether their crop is smaller than normal because of a relatively new pest-the soybean aphid.



Matthew O'Neal, an assistant professor of entomology at Iowa State University, is an expert on insects that attack soybeans. "My lab works on everything from developing varieties of soybeans that are resistant to aphids, to the best and most efficient use of insecticides, to biological control and managing habitat for improved beneficial insect abundance and diversity," he said.



Aphid-resistant soybean varieties will be available for the first time for the 2010 season. "Our research shows these varieties may reduce the number of insecticide applications needed to manage soybean aphids," O'Neal said.
