Be aware that Emerald ash borer is an exotic species that was reported in
Detroit feeding on green ash in 2002. This pest is originally from Asia and
attacks ash trees. Like a two-lined chestnut borer, the larvae of this beetle
feed in the phloem and outer sapwood of trees. The beetle apparently has a
one year life cycle with adults present from late May through late June. Dead
dying ash trees with watersprouts at the roots should be inspected for D-shaped
holes and tunnels of packed hardened frash.
If you think you have this pest, you should alert the Indiana Department of Natural Resources as follows:
IMMEDIATELY report the information by calling the Indiana Department of Natural Resources at (317) 232-4120.
Note the date and location where you found the beetle or damaged tree.
Capture the beetle in a plastic jar and place it in the freezer to kill it.
Carefully wrap the beetle and send it to:
Division of Entomology and Plant Pathology
402 West Washington Street, Room W290
Indianapolis, IN. 46204-2739
