DES MOINES, Iowa (AP) - Iowa agriculture officials say a beetle that infects and eventually kills ash trees has been found in two more counties.

The emerald ash borer is now confirmed in Grand Junction in Greene County and in Corydon in Wayne County.

The insect has now been confirmed in 43 Iowa counties.

The adult ash borer is metallic green and measures about one-half inch long. It can be noticed during the summer months.

Infected trees usually lose leaves at the top of the canopy and the die-off spreads downward. Trees usually die within two to four years.

A federal quarantine, enforced by the U.S. Department of Agriculture, remains in effect restricting movement of hardwood firewood and ash articles out of Iowa into non-quarantined areas of other states.

Iowans should use only local firewood.
