Agriculture officials say there's little movement in northeast Iowa of an invasive insect known for killing ash trees.
The Iowa Emerald Ash Borer Team says final results from surveillance efforts in 2012 show little movement from the emerald ash borer. Two traps last year indicated the metallic green beetles had moved inland from the Mississippi River.
The insect was spotted in 2010 on Henderson Island in the Mississippi River in Allamakee County. The latest data shows the insects are still in Allamakee County but no longer on the island.
The county has been under a federal and state quarantine since 2010. It prohibits the movement of such items like firewood, ash nursery stock and ash timber.
