Soybean aphids (Aphis glycines) have become the most significant insect pest in Minnesota soybean fields since their arrival in 2000. Feeding reduces bean yield and quality, but infestations can also introduce sooty mold or viruses to a crop.
MITPPC researchers are exploring new and improved aphid control options – from biological control with parasitic wasps to naturally aphid-resistant soybean lines. Aphids overwinter in another hard-to-control invasive species, buckthorn, that is the focus of other funded projects.
