New County Reports of Emerald Ash Borer

Since its discovery in 2009, emerald ash borer (EAB) has continued to invade Kentucky (Figure 1); Cumberland, Green, Taylor, and Wayne counties have been added to the list of counties this year. Designation as “infested” does not mean the insect is present throughout individual counties. However, very high ash mortality has occurred in unprotected trees within the triangular area bounded by Jefferson, Fayette, and Boone counties.

Information on the emerald ash borer in Kentucky is available at UK’s Kentucky Emerald Ash Borer website.
