Minnesota, federal agencies using wasps to slow emerald ash borer

This September, the Minnesota DNR, Minnesota Department of Agriculture, and the U.S. Forest Service will complete a joint biological control effort to slow the spread of emerald ash borer (an invasive beetle from Asia) in the Chippewa National Forest. The effort, known as the parasitoid wasp program, involves the release of three species of non-stinging wasps to target EAB at different life stages, helping slow EAB without harming other species.
