Field Testing Bugs with a Taste for Soybean Aphids
July 27, 2007| |
Aphids feeding on soybeans were introduced in Minnesota in 2000, and currently account for loses of $200 million annually in production loses and chemical pest control. Scientists of the University of Minnesota are currently testing a beneficial insect that could be used as a biological control agent: Binodoxys communis, a stingless wasp that kills soybean aphids.
"The soybean aphid was imported without any of its natural enemies, the organisms that keep aphids in check in China," said Dave Ragsdale, a University of Minnesota entomologist. "Our researchers and extension experts are working to provide that check-and-balance system in Minnesota."
