The emerald ash borer (EAB), Agrilus planipennis, is an exotic insect pest from Asia. The flattened, creamy white larval stage feeds below the bark and cuts off the living, water and nutrient conducting vessels causing tree death. EAB has been found in 13 Iowa counties (Allamakee, Black Hawk, Boone, Bremer, Cedar, Des Moines, Henry, Jasper, Jefferson, Muscatine, Story, Union, and Wapello). As of February 2014, all 99 counties in Iowa have been quarantined (Treatment Map) by the Iowa Department of Agriculture and Land Stewardship to slow the movement of this destructive pest to non-quarantined areas/states.
