Ash and Honey Locust Plant Bugs in Minnesota
The most common tree feeding plant bugs in Minnesota are the ash plant bug and the honey locust plant bug. The ash plant bug feeds on green, white and black ash while the honey locust plant bug feeds on all varieties of honey locust planted in urban landscapes.
The Emerald Ash Borer (Agrilus planipennis Fairmaire), commonly referred to as EAB, was introduced to the United States from Asia and first detected in southeast Michigan in June 2002. This destructive beetle has killed tens of millions of ash trees where it has been discovered.
EAB was discovered in St. Paul in May 2009. The City of Columbia Heights has been preparing for the ash borer's arrival since 2013, when city leaders adopted a plan to prepare for and manage it.
Crews have removed unhealthy ash trees and used two-year, ongoing cycle treatments for larger, healthy trees. City officials are encouraging private property owners with ash trees to consider plans for treatment or removal.
There are approximately 870 million ash trees in Minnesota, one of the largest concentrations of any state in the country. Select the following links for more information: mda.state.mn, dnr.state.mn, EAB University webinars.
