Emerald Ash Borer
Emerald ash borer was first found in the state of Minnesota in 2009. Native ash trees have no known resistance to this insect. It is currently found in two areas of the state: southeastern Houston County, and the cities of St. Paul/Minneapolis. Our lab is working with the various state and federal agencies to implement biological control of this insect as another management tool to reduce or slow ash mortality.
