Does host origin influence patterns of utilization in brown marmorated stink bug (Halyomorpha halys)?

Brown marmorated stink bug (BMSB), Halyomorpha Halys (Stål) (Hemiptera: Pentatomidae) is a major nuisance pest throughout the mid-Atlantic region.  BMSB is often observed in residential areas either on ornamental plants during the spring, summer, and fall or in residential structures during winter months.  The reasons for patterns of host use within urban landscapes are little understood, but critical to designing stink bugs out of urban landscapes and, consequently, the public’s lives.  Surveys were conducted to evaluate the influence of host plant origin on patterns of use by BMSB.  Patterns of utilization were evaluated by measuring the number of BMSB adults, nymphs, and egg masses on ornamental plants and shrubs of varying geographic origin.  Surveys were conducted at two commercial nurseries in Central Maryland during the May-September 2011 and May-September 2012. Results and implications of the surveys to designing sustainable landscapes will be discussed.
