Ash borer moves west, but new pests lie in wait

Updated:
FORT WAYNE, Ind. -

The emerald ash borer is leaving behind millions of dead or dying trees as it marches west from Indiana, and experts say new pests are waiting in the wings to take its place.

Many of the state's 150 million ash trees have died or are dying as a result of the metallic-green beetle that arrived in the United States in 2002 from Asia.

Phil Marshall of the Indiana Department of Natural Resources tells The Journal Gazette that the state continues to monitor the spread of the ash borer. But officials also are keeping their eye on the walnut twig beetle and the Asian long-horned beetle.

The walnut twig beetle targets black walnut trees. The Asian beetle can kill eight hardwood species. Both are near Cincinnati and moving west.
