Adult Emerald Ash Borer
|
Emerald Ash Borer (Agrilus Planipennis), an ash tree-killing insect from Asia, was identified in Ohio in 2003. The
department has been battling the pest through detection,regulation, and education in an attempt to protect the state’s more than 3.8 billion ash trees.
The pest has since spread from the initial detection in near Toledo to its present distribution in 56
counties. Because the pest has been found throughout most of Ohio, including Wayne National Forest,
there are no longer quarantine regulations in place for emerald ash borer within the state.
Despite the fact that the Ohio quarantine has been lifted, it is still recommended that Ohioans continue
to exercise caution when moving firewood.
EAB kills ash trees within three to five years of infestation. Adults are dark metallic green, 1/2 inch in length and
1/8 inch wide, and fly only from mid-May to September. Larvae spend the
rest of the year developing beneath the bark.
To date, infestations have been identified in Allen, Ashland, Auglaize, Butler, Clark, Clermont, Clinton, Cuyahoga, Darke, Defiance,
Delaware, Erie, Fairfield, Franklin, Fulton, Geauga, Greene, Hamilton, Hancock, Hardin, Henry,
Huron, Lake, Lawrence, Licking, Logan, Lorain, Lucas, Mahoning, Marion, Medina, Mercer, Miami,
Montgomery, Morrow, Ottawa, Paulding, Perry, Pickaway, Pike, Portage, Putnam, Richland, Sandusky, Scioto, Seneca, Shelby, Summit, Trumbull,
Union, Van Wert, Warren, Wayne, Williams, Wood, and Wyandot
counties.
