Abstract:		"The invasive brown marmorated stink bug, Halyomorpha halys (Stal), is a pest of numerous economically important crops in the USA. In the Mid-Atlantic region, it is a significant, direct pest in tree fruit orchards, many of which are bordered by woodlots containing a variety of its deciduous tree and shrub hosts. During the growing season, H. halys moves from woodland habitats into crops, but seasonal changes in its relative abundance between these adjacent habitats have not been examined. Using linear transects of six pheromone-baited pyramid traps that extended from 100 m into the interior of woodlots to 100 m into the interior of adjacent commercial apple orchards in Virginia, spatiotemporal changes in H. halys captures were measured during three growing seasons. Captures of H. halys adults and nymphs were recorded weekly from May through October, and annual data were separated into early, mid, and late-season captures. Only adults were captured during the early season, and there was no indication of a spatial trend in captures across traps in the transects among years. Beginning in mid-season and becoming increasingly apparent by late season, captures of H. halys adults and nymphs tended to become most frequent in traps at the woods and orchard edges and at 50 m into the orchard interior. These findings conform with and expand upon previous research documenting an edge effect for H. halys relative abundance and can inform and support the optimization of perimeter-based management strategies for H. halys in Mid-Atlantic apple orchards"
