Emerald Ash Borer
Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle from Asia that was discovered (in North America) near Detroit, Michigan in the summer of 2002. The adult beetles nibble on ash foliage, causing little damage. However, the larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients, eventually killing the tree. The emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes arriving from Asia, and has most likely spread by hitchhiking on firewood transported among homes and recreation areas in more than 20 states. In addition to Missouri, the emerald ash borer has been found in Connecticut, Colorado, Illinois, Iowa, Indiana, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, Wisconsin as well as in Canada. It was discovered in southeast Missouri in July 2008 in Wayne County and in September 2013 Missouriís quarantine expanded to include all 114 counties and the City of St. Louis.
Since its discovery in the US, EAB has killed trees, created regulatory headaches and cost millions in control measures:
- Killed tens of millions of ash trees in more than 20 states.
- Caused regulatory agencies to enforce quarantines and fines to prevent potentially infested ash trees, logs or firewood from moving out of areas where EAB occurs.
- Cost municipalities, property owners, nursery operators and forest products industries millions of dollars.
