REVIEW Range expansion of the invasive brown marmorated stinkbug, Halyomorpha halys: an increasing threat to field, fruit and vegetable crops worldwide Tim Haye 1,7 • Tara Gariepy 2 • Kim Hoelmer 3 • Jean-Pierre Rossi 4 • Jean-Claude Streito 4 • Xavier Tassus 5 • Nicolas Desneux 6 Received: 14 January 2015 / Revised: 17 April 2015 / Accepted: 27 April 2015 / Published online: 5 May 2015 Ó Springer-Verlag Berlin Heidelberg 2015 Abstract The brown marmorated stink bug, Halyomor- pha halys (Hemiptera: Pentatomidae), has emerged as a harmful invasive insect pest in North America and Europe in the 1990s and 2000s, respectively. Native to eastern Asia, this highly polyphagous pest ( [ 120 different host plants) is spreading rapidly worldwide, notably through human activities. The increasing global importance of the pest suggests that more coordinated actions are needed to slow its spread and mitigate negative effects in invaded areas. Prevention of large-scale outbreaks will require ac- curate identification and effective mitigation tools to be rapidly developed and widely implemented. In this short review, we update the current distribution of H. halys, discuss potential geographic range expansion based on passive and active dispersal and provide insight on the economic, environmental and social impact associated with H. halys.

Introduction Native to eastern Asia, the brown marmorated stink bug (BMSB), Halyomorpha halys (Sta ˚l, 1855) (Hemiptera: Pentatomidae), has recently become one of the most harmful invasive insect pests in North America and Eur- ope. In the US, this pest was first discovered in Allentown (Pennsylvania) in 1996, whereas the first records from Europe (Switzerland, Liechtenstein) date back to 2004 (Hoebeke and Carter 2003; Arnold 2009; Haye et al. 2014). Since its arrival in the US, H. halys has spread to 41 states Communicated by M.
