From the MDA: Brown marmorated stink bug

| Leave a comment
From Roger Wippler, UMN Ext Master Gardener, Ramsey County - thanks Roger! - jw

The brown marmorated stink bug (Halyomorpha halys) is originally from Asia and was Stinkbug.jpgfirst identified in the U.S. in 2001.  In eastern states it has become a well known household invader and more recently has begun to cause significant crop damage.  This insect is known to attack a long list of plant species including field crops, fruits, vegetables, and ornamentals. 

The brown marmorated stink bug was first detected in Minnesota in November of 2010 in Ramsey County, and has since been detected in Anoka, Washington and Winona counties.  In all cases the bugs were found in houses or other buildings.  The extent of the infestation and potential impacts in Minnesota remain unknown.  In 2011, the MDA will conduct a statewide survey of soybeans and a couple other surveys to determine the extent of the infestation.  The U of MN will begin some more detailed survey work in orchards and vineyards.  Funding is being sought by MDA and the U of MN to begin examining the potential impacts to Minnesota crop varieties and evaluating the efficacy of treatment options.
