"Research fields at the University of Minnesota St. Paul Campus are one of the sites where researchers are field testing a beneficial insect that kills soybean aphids. Releases will be initially made in cages to confine the aphids and parasitoids. Once scientists see new parasitoids emerging in 10-12 days, cages will be removed and parasitoids will be allowed to attack aphids in the field. University of Minnesota Entomologists Dave Ragsdale, shown left, and George Heimpel are shown with one of the cages." |
"Researchers look for mummies, the darker brown objects on the soybean leaf shown above, to gauge the effectiveness of the beneficial insect in controlling soybean aphids. The light green spots on the soybean leaf are soybean aphids." |
