Emerald Ash Borer Detected In Northwest Iowa

Thu 6-15-2017

(Alta)-- Emerald Ash Borer has been detected for the first time in northwest Iowa.

Mike Kintner of the Iowa Department of Agriculture and Land Stewardship says evidence of the pest has been found in an ash tree in Alta, in Buena Vista county.

Emerald Ash borer was first detected in Iowa in 2010. It's now been detected in 50 of the state's 99 counties.

Emerald Ash Borer infested trees display canopy dieback at the top of the tree that progresses downward along with S-shaped feeding galleries under dead or splitting bark, D-shaped exit holes, water sprouts along the truck and main braches, and bark that is stripped off. The adult beetle is metallic green in color and measures about a half inch long. It can be seen in the summer. The larvae burrow through the inner layer of bark, feeding on vascular tissue that moves water and nutrients through the tree. Infested trees usually die within two to four years.
