The brown marmorated stinkbug, Halyomorpha halys Stal (Heteroptera: Pentatomiidae) was discovered in Hagerstown, Maryland (Washington County) in October 2003. This exotic stinkbug was first discovered in the United States in Allentown, Pennsylvania in October, 2001 and is currently found in five counties in southeastern Pennsylvania and two counties in New Jersey. Halyomorpha halys is a major nuisance pest, entering homes seeking warm sheltered sites to overwinter and is considered an agricultural pest in Asia where it is native. Residential growers in Allentown, Pennsylvania have reported damage to backyard fruit trees. Damage has not been reported on a commercial scale, but growers should be on the lookout for this new potential pest.
