INDIANAPOLIS — A beetle that kills ash trees has been found for the first time in six southern Indiana counties as the pest continues its march across the state.
The Indiana Department of Natural Resources said Friday the emerald ash borer has been detected in Jennings, Pike, Scott, Spencer, Sullivan and Warrick counties.
That means the pest has now been detected in 79 of Indiana's 92 counties.
The agency says the new ash borer detections raise questions about the effectiveness of quarantines on wood from ash trees. The DNR says a decision will be announced next year on whether those quarantines will continue.
The beetle that's native to Asia has killed about 50 million ash trees in the Upper Midwest since arriving in the U.S. more than a decade ago.
