Emerald Ash Borer Detected in Bucks County!
Posted: March 14, 2012
On Wednesday, March 14 Pennsylvania Department of Agriculture confirmed that Emerald Ash Borer (EAB) has been detected in Warrington, Bucks County. The infestation was first observed by an arborist who contacted Penn State Extension. Department of Agriculture entomologists collected specimens at the site on March 12 and positively identified larvae taken from infested trees.
Emerald ash borer (Agrilis planipennis) is a threat to all ash (Fraxinus) species in Pennsylvania. It is estimated that EAB has killed more than 50 million ash trees since its original detection in Michigan in 2002. Fifteen states and two Canadians provinces are infested. In Pennsylvania, EAB has been moving east since the original detection in 2007.
The detection in Bucks County is the first in Southeastern Pennsylvania.
Penn State’s Emerald Ash Borer website is an excellent portal to research-based fact sheets, pictures and reports on this important insect, including the National EAB website , as well as links to information from states such as Michigan which have the most experience with the devastation caused by this insect.
Arborists may be particularly interested in The North Central IPM Center publication titled: Insecticide Options for Protecting Ash Trees From Emerald Ash Borer, written by Extension entomologists in North Central United States. An overview of the basic biology of EAB can be found in the US Forest Service Emerald Ash Borer Alert .
The “Frequently Asked Questions” feature at the Penn State site provides information to concerned property owners.
Finally, A Homeowners Guide to Emerald Ash Borer Treatment provides guidance for property owners who are considering a do-it-yourself approach to treatment.
Detection of EAB in Southeastern Pennsylvania has important consequences for property owners and communities where ash exists. Fortunately, research-based information from Penn State, and Land Grant Universities in states to our west, is abundant.
