Complete report of the genetic analyses performed in a study investigating the genetic diversity of the Brown Marmorated Stink Bug Halyomorpha halys in Belgium. This study was submitted to NeoBiota with the following title: Distribution and genetic diversity of the invasive pest Halyomorpha halys (Hemiptera: Pentatomidae) in Belgium. Abstract: The brown marmorated stink bug, Halyomorpha halys, native to East Asia, is an invasive pest of economic importance. It has mainly invaded North America and many European countries and is further expanding its range in Europe. In Belgium, it was first observed in 2011. Halyomorpha halys is known to cause severe damage in vegetable crops and in commercial fruit orchards. Therefore, a dramatic and unmitigated expansion of H. halys in Belgium could lead to significant economic implications for fruit production. In this study, occurrence data of H. halys since its first observation in Belgium was analysed together with molecular information to map the populations and ...
