        The introduction of Halyomorpha halys, the brown marmorated stink bug (BMSB) (Hemiptera: Pentatomidae), in the USA and Europe has disrupted many established fruit, vegetable and row crop Integrated Pest Management (IPM) programs. BMSB poses a profound threat to many crops because of its broad host range, strong dispersal capacity, well-concealed overwintering populations, as well as the fact that biological control from native natural enemies has been limited and very few registered insecticides are considered effective. The need for sensitive biosurveillance and monitoring tools in uninvaded and invaded regions, respectively, as well as alternative management tactics to reduce insecticide inputs has been paramount. The identification of the BMSB pheromone, (3S,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol and (3R, 6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol in a 3.5:1 ratio and pheromone synergist methyl (2E,4E,6Z)-2,4,6-decatrienoate has rapidly propelled the development of these tools and tactics. Pheromone-baited traps deployed with these stimuli have been evaluated across invaded regions in the USA and Europe and in the native range in South Korea. In every case, traps baited with the combination of the BMSB pheromone and pheromone synergist captured greater numbers of BMSB than traps baited either stimulus alone indicating that these trapping systems can be used for worldwide biosurveillance. Moreover, baited traps have been used as sensitive IPM tools to guide management decisions in affected crops such as apple. Finally, these pheromonal stimuli have served as the basis for successful attract and kill programs in affected crops. While refinement of these tools and tactics continue, their use has resulted in significant reductions in insecticide inputs in apple crops, for example, and successful biosurveillance in newly invaded regions.
