AMES, Iowa — The Emerald Ash Borer is an insect that, in a matter of time, will destroy all ash trees. Because the bug has begun making its way across Iowa, an Iowa State University Extension and Outreach entomologist, in collaboration with an Iowa Department of Agriculture and Land Stewardship entomologist, has written a new publication to help Iowans identify signs of the pest under the bark.
“EAB or Native Borer?” by Mark Shour and Todd Voss offers a side-by-side comparison of the Emerald Ash Borer and several Native Borers, which only attack declining or dying ash trees. The exotic Emerald Ash Borer, in contract, kills healthy and declining ash trees. The publication (PM3065) is available for free download from the ISU Extension and Outreach Online Store, https://store.extension.iastate.edu/.
