Stink bugs (Hemiptera: Pentatomidae) are ubiquitous, cryptic, phytophagous pests that are found in many crops. In agroecosystems, individuals disperse from adjacent noncrop hosts and tend to aggregate or cluster within fields. In this study, we characterized the distribution of Euschistus servus (Say) and Euschistus tristigmus (Say) (Hemiptera: Pentatomidae) over 2 yr at three southeastern United States farmscapes. Stink bugs were captured in pheromone-baited traps, and Spatial Analysis by Distance Indices (SADIE) used to identify the location of significant aggregations by habitat type and season. Euschistus servus adults were more likely to be captured in pecan orchards, cotton, other crops, or unmanaged habitats than in woodland habitats. Significant aggregations of E. servus were detected in a variety of habitats including pecan, corn, cotton, peanut, and tobacco, as well as fallow and hay fields, pastures, and hedgerows. Fewer adult E. tristigmus were captured than E. servus adults, and E. tristigmus adults were typically trapped and aggregated in woodland habitats. The resulting data provide an important understanding regarding the seasonal movement and relative abundance levels of stink bug populations, which are critical to the development of integrated pest management strategies.

两种 Euschistus spp 的时空分布。东南农场景观中的臭虫（半翅目：蝽科）

臭虫（半翅目：蝽科）是普遍存在的、神秘的、植食性害虫，存在于许多作物中。在农业生态系统中，个体从邻近的非作物宿主中分散，并倾向于在田间聚集或聚集。在这项研究中，我们在美国东南部的三个农场景观中描述了 Euschistus servus (Say) 和 Euschistus tristigmus (Say) (半翅目: Pentatomidae) 超过 2 年的分布情况。臭虫在信息素诱捕器中被捕获，距离指数空间分析 (SADIE) 用于根据栖息地类型和季节确定重要聚集体的位置。Euschistus servus 成虫在山核桃园、棉花、其他作物或无人管理的栖息地比在林地栖息地更容易被捕获。在包括山核桃、玉米、棉花、花生和烟草，以及休耕和干草田、牧场和树篱。捕获的成年 E. tristigmus 少于 E. servus 成虫，并且 E. tristigmus 成虫通常被困在林地栖息地并聚集在一起。由此产生的数据为了解蝽种群的季节性运动和相对丰度水平提供了重要的理解，这对于制定综合虫害管理战略至关重要。
