Stingless Wasps-EAB

The Minnesota Department of Agriculture has confirmed that stingless wasps are doing their job in attacking emerald ash borer in Winona County.

Two years after releasing the wasps at Great River Bluffs State Park near Dakota, MDA staff has found reproducing wasp populations. This is the first time this wasp species has been recovered in Minnesota.

The wasps are part of a biological control effort to naturally slow the spread of the Emerald Ash Borer. The wasps do not attack humans.
The MDA says this is a major step in the battle with EAB and confirms the wasps are attacking the ash borers and reproducing in the field.

The MDA first released stingless wasps in Great River Bluffs State Park in September 2011. Wasps have also been released in Houston County and the Twin Cities, all areas known to be infested with the emerald ash borer.....
