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:

INVASIVE EMERALD ASH BORER DETECTED IN ARKANSAS

For Immediate Release: July 18, 2014

Arkansas Agriculture Department/Arkansas State Plant Board officials today confirmed that the emerald ash borer (EAB), an invasive beetle that attacks and kills ash trees, has been found in Hot Springs, Clark, and Nevada counties.

Beginning in 2009 the Arkansas State Plant Board and the United States Department of Agriculture, Animal Plant Health Inspection Service, Plant Protection and Quarantine (USDA APHIS PPQ), through a cooperative program, have conducted an Emerald Ash Borer survey. The survey has been ongoing with USDA APHIS PPQ surveying approximately one half of the state and the Arkansas State Plant Board surveying the remaining counties. The survey consists of placing traps and inspecting Ash trees for signs of EAB infestations.

Emerald Ash Borers have been detected in traps placed in Hot Springs, Clark, and Nevada counties. The insect specimens from the Hot Springs and Clark county traps were sent to scientists at USDA APHIS PPQ, who have confirmed the insect's identity. The insects trapped in Nevada County have been screened by an Arkansas State Plant Board entomologist and are considered highly likely, however official confirmation will be made by USDA APHIS PPQ scientists.

EAB is now present in 24 U.S. states and two Canadian provinces. It was first discovered in Michigan in 2002 and has since killed tens of millions of trees.

The adult emerald ash borer is a metallic green insect about one-half inch long and one-eighth inch wide making it hard to detect in the wild. The female beetles lay eggs on the bark of ash trees. The eggs hatch and the larvae bore into the bark to the fluid-conducting vessels underneath. The larvae feed and develop, cutting off the flow of nutrients and, eventually killing the tree. EAB attacks and kills North American species of true ash, and tree death occurs three to five years following initial infestation. EAB is native to Asia.

Signs of EAB include: canopy dieback beginning at the top of the tree and progressing through the year until the tree is bare; sprouts growing from the roots and trunk; split bark with an S-shape gallery; D-shaped exit holes; and more woodpecker activity, creating large holes as they extract the larvae.

State and USDA APHIS PPQ personnel will now survey trees in the areas surrounding the initial finds to determine the extent of the EAB infestation. It is expected that a federal quarantine will be expanded to include parts of Arkansas and potentially the entire state.

To prevent the spread of this beetle, do not move firewood. Firewood is a vehicle for movement of tree-killing forest pests including EAB and Asian longhorned beetle. Use locally-sourced firewood when burning it at home. When travelling, burn firewood where you buy it. Make sure to burn all wood purchased.

Report signs of the beetle to the Arkansas State Plant Board at 501-225-1598.

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.
