BACKGROUND Brown marmorated stink bug (BMSB), Halyomorpha halys (Stål), is an invasive and severe pest of specialty and row crops. A 2‐year field study conducted in four Mid‐Atlantic states in the USA characterized the spatial and temporal dynamics of BMSB populations and its association with landscape elements in commercial agriculture settings. In each state, two 1 km2 sites included typical landscape elements (i.e., tree fruit orchards, annual field and vegetable crops, woodlands, and human‐made structures). Twenty‐seven georeferenced pheromone traps were deployed per site and the number of BMSB adults and nymphs captured was counted throughout the growing season. RESULTS Findings from spatial analysis by distance indices, along with time‐series maps of BMSB distribution, showed that BMSB exhibited significant spatial aggregation, and that its distribution was spatially consistent between years. Analyses with geographic information systems (GIS) revealed that BMSB ‘hot spots’ occurred in different landscape elements throughout each season. Most patches (i.e., clusters of significantly higher trap captures) were found near woodlands early in the season, near tree fruit orchards in summer, and on the border of annual field crops in autumn. Buffer analysis with GIS indicated that more BMSB adults were captured closer to woodlands compared with other landscape elements. CONCLUSION Understanding the spatial and temporal movement and distribution of BMSB is critical to predicting their potential impact and ultimately devising strategies to mitigate this risk to vulnerable crops. The results of this study can be used to design streamlined, spatially‐based areawide management of BMSB in heterogeneous and complex agricultural landscapes. © 2023 Society of Chemical Industry.

A 2‐year study of spatial and temporal dynamics of brown marmorated stink bug in four mid‐Atlantic states revealed ‘hot spots’ were associated with different landscape elements throughout the growing season. Most ‘hot spot’ clusters were detected near woodlands in the spring, near fruit orchards in the summer and annual crops in the autumn.
