philly.com is reporting that the emerald ash borer (Agrilus planipennis) has been found in Pennsylvania. The beetles were found June 22 on the western edge of the state, in Butler County. According to this website, Pennsylvania has been surveying the western portion of the state for the presence EAB since 2003
As a result of the discovery, the Pennsylvania Department of Agriculture has placed a quarantine on the movement of all firewood in Butler County and the neighboring Allegheny, Beaver, and Lawrence Counties. While other states dealing with the EAB have specifically targeted ash wood and wood products, Pennsylvania is taking a more pragmatic stance. Noting how difficult it is to determine the type of tree that firewood comes from, they're quarantining all hardwoods.
