The Nebraska Department of Agriculture in partnership with the U.S. Department of Agriculture, confirmed emerald ash borer in a tree in Kearney. Kearney Park and Recreation staff discovered the tree on a street terrace and reported it to NDA. This is the first detection of EAB in Buffalo County, and the first find outside of eastern Nebraska. EAB, an invasive beetle that attacks and kills ash trees, was first found in Omaha in 2016.
“As more people recognize the signs and symptoms of EAB in ash trees and as EAB continues to move, we can expect to find additional infestations in Nebraska,” said NDA Director Steve Wellman. “By monitoring for EAB, creating quarantine orders and teaching home owners and communities how to help slow the spread of this destructive pest, NDA and the Nebraska EAB Work Group have given people more time to prepare for the arrival of EAB and develop plans for disposing of and managing infested trees.”
EAB is a small, metallic-green beetle that is about one-half inch long. The larvae of this wood-boring insect tunnel under the bark of ash trees, disrupting the flow of water and nutrients, ultimately causing the tree to die. EAB-infested ash trees will exhibit thinning or dying branches in the top of the tree, S-shaped larval galleries under bark, D-shaped exit holes and suckers (along the trunk and main branches).
Cass, Dodge, Douglas, Lancaster, Otoe, Sarpy, Saunders and Washington counties remain under a quarantine, first issued in 2016 and updated in 2018, which includes prohibiting ash nursery stock from leaving the quarantine area and regulating the movement of hardwood firewood and mulch, ash timber products and green waste material out of quarantined areas. Quarantines are put in place to reduce the human-assisted spread of EAB into non-infested areas. NDA and USDA staff work with the public and impacted industries to ensure compliance of quarantines. NDA will make any updates to the state EAB quarantine this fall, after adult flight is over and trapping has been completed.
