Spatiotemporal Distribution of Stink Bugs (Hemiptera: Pentatomidae) in Peach Orchards and Surrounding Habitat

Stink bugs (Hemiptera: Pentatomidae) are economic pests of a variety fruit crops across the southeastern USA, and damage by stink to peaches is common. The landscape surrounding orchards may influence bug distribution dispersal into this commodity, but such patterns vary over growing season. Accordingly, control should be targeted seasonally towards habitats that effectively reduce or prevent peach. In study, we used pheromone-baited traps characterize 2 species, Euschistus servus (Say) tristigmus (both Hemiptera: Pentatomidae), in peach habitat seasons at 3 sites central Georgia, USA. addition, Spatial Analysis Distance Indices identify significant aggregations each species duration seasons. Adults captured differed varied wk sampled. was commonly found peaches, whereas E. not. Regardless orchard yr, adult tended avoid woodland habitat, prefer type. Both increased later season with spatial detected all orchards. However, which were yr. Across orchards, adults clustered mainly trees adjacent pecan, as well pine, fallow, kudzu habitat. Adult aggregated primarily woodland, pecan Seasonal suggest measures need implemented on fine scale non-crop habitats.
