MARENGO, Iowa (AP) - State officials say an invasive insect that kills ash trees has been discovered in two more counties, raising the total in Iowa to 38 counties.

The Iowa Department of Agriculture said Thursday that emerald ash borer larvae were found at Lake Orient Recreation Area in Adair County and in a rural area north of Cromwell in Adams County.

The insects have killed tens of millions of ash trees and have now been found in 28 states. They are native to Asia and were first reported in the U.S. in Michigan in 2002. The insects were first detected in Iowa in 2010.
