Emerald Ash Borer
Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. The adult beetles nibble on ash foliage but cause little damage. The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. Emerald ash borer is also established in Windsor, Ontario, was found in Ohio in 2003, northern Indiana in 2004, northern Illinois and Maryland in 2006, western Pennsylvania and West Virginia in 2007, Wisconsin, Missouri and Virginia in the summer of 2008, Minnesota, New York, Kentucky in the spring of 2009, Iowa in the spring of 2010, Tennessee in the summer of 2010, Connecticut, Kansas, and Massachusetts in the summer of 2012, New Hampshire in the spring of 2013, North Carolina and Georgia in the summer of 2013, Colorado in the fall of 2013, New Jersey in the spring of 2014, and Arkansas in the summer of 2014. Since its discovery, EAB has:

Free Webinar Series this Fall Deals with Emerald Ash Borer and other Invasive Wood Pests

Awareness of tree pests and diseases threatening the health of trees in communities, forests and woodlands goes a long way toward making informed decisions about their care.

Emerald Ash Borer University (EABU) is a free webinar series created to bring awareness, education and information about tree pests and diseases. Webinar participants are involved in live presentations given by experts from communities, universities, and state and federal organizations who deal with these issues. The presentations end with question and answer sessions.

Tree care companies, arborists, urban foresters, landowners, educators and others involved in tree management will find these webinars beneficial. The EABU webinars are held on Thursdays (unless otherwise noted) for one hour, twice a month, beginning Thursday, October 23 at 11 a.m., Eastern Time, and running until December.

"EABU was created to bring timely, reputable information about wood pests and diseases to as broad an audience as possible," Cliff Sadof, entomologist at Purdue University and EABU co-coordinator, says. "These free webinars are an excellent way to gain knowledge from the experts, and get questions answered that can enlighten participants and provide solutions involving tree management."

Webinar topics this fall range from wood utilization to case studies on emerald ash borer, woodlot management before, during and after pest infestations, to comparing wood-boring pests, and clearing up misinformation about pest management.

Continuing education credits for participating in certain webinars may be available.

Each webinar presentation is recorded and available for viewing on the website the day after the webinar is aired. Past webinars are archived, so those unable to participate in live webinars can watch them at anytime from their computer.

Funding for EABU comes from the United States Department of Agriculture (USDA) Forest Service, and is coordinated by communicators and educators at Purdue University, Michigan State University, and the Ohio State University.

New Strategy Being Developed to Deal With Emerald Ash Borer

  • Research is being conducted at universities, as well, to understand the beetle's life cycle and find ways to detect new infestations, control EAB adults and larvae, and contain the infestation.
  • Quarantines are in place to prevent infested ash firewood, logs or nursery trees from being transported and starting new infestations.

This Website provides information from Michigan State University, Purdue University, the Ohio State University, the Michigan and Ohio departments of Agriculture; the Michigan, Indiana and Ohio departments of Natural Resources; the USDA Forest Service; the USDA Animal and Plant Health Inspection Service (APHIS); and the Canadian Food Inspection Agency. Our goal is to help you find answers to your questions about EAB. We also provide links to other EAB-related Websites. Please check this site often because information changes frequently.

Scientists are studying methods of controlling EAB. The latest information on insecticide evaluations can help homeowners, arborists and landscapers decide if and how they can treat trees for EAB.


IMPORTANT NOTE: Since the emerald ash borer's discovery in 2002, research has been ongoing to develop tools to control and eliminate this pest. Currently, there are a number of treatments available for use by homeowners or tree care professionals that can provide a varying degree of beetle control. A review of all options is recommended, as well as knowing the regulations regarding EAB quarantines and eradication strategies for your area. Contact your state department of agriculture for more EAB regulatory information. As more methods of EAB control are developed, more information will be available.
