Native to East Asia, the brown marmorated stink bug (Halyomorpha halys; Fig. 1) damages fruit, vegetables, berries and field crops (Leskey and Nielsen, 2018). The species was introduced into the USA towards the end of the 20th century, and spotted for the first time in Europe (in Zurich) in 2004 (Wermelinger et al., 2008). By now, it is already present in many European countries (Haye et al., 2015). The bug is 12 to 17 mm long and active from April to October. South of the Alps it usually produces two generations, north of the Alps one generation per year. For overwintering, it seeks out sheltered spots on outdoor walls or in buildings.
Since its first sighting the canton of Zurich in 2004, the brown marmorated stink bug has spread over large parts of Switzerland, including the Central Plateau, the area around Basel, between Bern and Lake Geneva, Ticino, and recently, the Valais. These observations coincide with the potential range calculated with the aid of a bioclimatic simulation model (CLIMEX; Kriticos et al., 2017) (Fig. 2).

According to results of simulations with the same model, in future the range of the brown marmorated stink bug is likely to expand further, encompassing the entire agricultural production area of Switzerland towards the end of the current century, although increasing heat stress could limit its growth potential in southern Switzerland. North of the Alps, the spread of the brown marmorated stink bug will be favoured by milder winters and higher spring and autumn temperatures. In all regions, an additional generation per year can be expected in future.
The search for an effective control strategy is elusive, since the bug attacks many plant species, is exceptionally mobile, and is resistant to authorized insecticides. Monitoring is therefore all the more important. Since 2004, The Centre for Agriculture and Biosciences International (CABI) has been running a web platform with information and up-to-date detection notifications. In 2017, the agricultural sector launched a joint national monitoring scheme involving Agroscope, FiBL, CABI and cantonal plant-protection services. An optimised monitoring with a mobile app is also the aim of the Interreg Oberrhein ‘InvaProtect’ Project.
