The emerald ash borer, an invasive insect that kills ash trees, has not spread to far Southwestern Indiana counties, according to the Department of Natural Resources.

According to the Evansville Courier & Press, the DNR placed traps to attract emerald ash borers during the spring and the summer to see if they had spread to the region.

"The 82 purple traps placed on the designed grid did not capture any of the beetles," said Phil Marshall, the state entomologist.

The traps were set in 13 Southwestern Indiana counties, including Gibson, Posey, Vanderburgh and Warrick.

The emerald ash borer has been detected across the state, but most of the sightings are in the northeast.

At the start of 2012, a total of 28 quarantined counties did not have an emerald ash borer infestation. From the 2012 survey, emerald ash borers were detected for the first time in Henry, Newton and Wayne counties.

In addition to those detections, emerald ash borers were found for the first time in 38 new townships in 18 infested counties and in the cities of Bloomington, Franklin and West Lafayette.

Detections provide information to guide landowners on management of their ash trees by letting them know how close emerald ash borer is. This information allows them to make more informed decisions about management options.

Seventy-nine counties are under quarantine because of emerald ash borers, all Indiana counties except those in the southwest.

To legally move regulated materials out of quarantined counties, Hoosiers must obtain a compliance agreement from the Indiana DNR. Regulated materials include firewood of all hardwood species, such as ash, oak, maple and hickory, nursery stock and green lumber of ash, any other ash material living, dead, cut or fallen including logs, stumps, roots, branches, as well as composted and uncomposted chips of the genus Fraxinus.

An application for a compliance agreement can be filed by calling 317-232-4120. To view quarantined areas and emerald ash borer sightings in Indiana, see
