LINCOLN, Neb. (AP) — Nebraska officials are trying to limit the spread of the emerald ash borer after the invasive insect that kills ash trees was discovered in Omaha.

The Nebraska Department of Agriculture issued a quarantine to prevent ash nursery stock from leaving the area, and a state senator announced Wednesday she will seek an increase in funding for a grant program to help remove and replace trees.

The Nebraska Department of Agriculture says the beetle was found in a Pulaski Park tree in Omaha. With Nebraska added to the list, there are now 27 states where the pest has been confirmed since 2002.

Department Director Greg Ibach has said the beetle’s presence in the state is not a surprise considering nearby states that already have infestations, including Iowa, Missouri and Kansas.
