Two new Asian parasitoids are now attacking the soybean aphid in Minnesota. One is Aphelinus certus, which became established on its own, and the other is Aphelinus glycinis, which we started releasing in 2013. Aphelinus certus, is a generalist aphid parasitoid that attacks not only soybean aphid but other aphids, including pests and non-pests alike, whereas A. glycinis is a specialist and attacks only soybean aphid and a few of its close relatives. Either one of these species on its own has the potential to substantially reduce soybean aphid pressure in Minnesota and elsewhere in North America. However, in order to best take advantage of the beneficial potential of these insects,...

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
