Release of the Emerald Ash Borer’s Insect Enemies Thursday, July 18
In response to emerald ash borer in Aroostook County

Augusta, MAINE - To battle the emerald ash borer (EAB) infestation, Maine Forest Service is releasing parasitoids in Aroostook County.  Parasitoids are tiny non-stinging wasps that feed in or on EAB by attacking immature (larvae) EAB under the bark of ash trees and parasitizing eggs on the surface of the bark. 

The parasitoid species being released in Aroostook County are Oobius agrili, Tetrastichus planipennisi and Spathius galinae. They were produced and supplied by the USDA APHIS PPQ EAB Parasitoids Rearing Facility in Brighton, MI. Learn more about parasitoids

EAB was found in Aroostook and York Counties in 2018. The northern infestation also includes towns in New Brunswick, where Canadian officials are releasing the same parasitoids. At this time, Department of Agriculture Conservation and Forestry entomologists are researching suitable sites for parasitoids release in Southern Maine.
