Stink bug damage and abundance on cotton in the southeast US has greatly increased in recent years. These insects have proven difficult to manage in a crop specific management plan because adults are highly mobile and can persist on a wide variety of cultivated and nonagronomic hosts. The objective of this study was to investigate the locations and hosts associated with stink bug overwintering, early population increases, and temporal colonization of hosts across a 163 hectare Georgia farmscape. Emerging overwintered stink bugs were found in grassy fencerows in unmowed pecan orchards. Spatial mapping of stink bug adult and immature captures during the summer and fall show that adult populations moved among multiple hosts, but immatures were consistently found in unmowed grass and on nonagromonic hosts. Data show that farmscape wide populations were not affected by local spraying of agronomic crops. These results suggest that managing stink bugs as an areawide pest may be a tenable strategy.
