Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), the brown marmorated stink bug, is an invasive polyphagous insect that can cause serious economic injury to specialty and row crops in the United States and globally. To date, H. halys has been managed with repeated insecticide applications. While progress has been made toward development of trap-based monitoring tools to guide management decisions, little is known regarding the trapping area over which a single pheromone-baited trap captures H. halys. We conducted single trap, multiple distance mark-release-recapture experiments; results were used to estimate trapping area for nymphs and adults in sites without host plants present (open field) and for adults in sites with host plants present (apple orchard). Plume reach for pheromone-baited sticky traps was consistently estimated to be <3 m. Maximum dispersive distance in an open field devoid of host plants was estimated to be 40 m for nymphs and 120-130 m for adults resulting in trapping areas of 0.58 ha and 4.83-5.56 ha, respectively. When traps were deployed in association with host plants within the border row of an apple orchard, adult maximum dispersive distance and trapping area was reduced to 70 m and 1.67 ha, respectively. These results indicate that the behavioral response of H. halys to pheromonal stimuli is influenced by the presence of host plants and that trapping area for pheromone-baited traps will likely change relative to the cropping system in which it is deployed. Caution should be taken when extrapolating these results, because the measured values may differ in other crop systems.
褐边绿刺蛾（Halyomorpha halys (Stål)，半翅目：蝽科）是一种入侵性多食性昆虫，会给美国乃至全球的特色作物和大田作物造成严重经济损失。迄今为止，褐边绿刺蛾的防治主要依靠反复喷施杀虫剂。虽然在开发基于诱捕器的监测工具以指导管理决策方面已取得进展，但对于单个性诱剂诱捕器捕获褐边绿刺蛾的诱捕面积却知之甚少。我们进行了单诱捕器、多距离标记重捕实验；结果用于估计在无寄主植物的场地（开阔地）若虫和成虫的诱捕面积，以及在有寄主植物的场地（苹果园）成虫的诱捕面积。性诱剂诱捕粘虫板的羽流范围一直估计小于3米。在没有寄主植物的开阔地，若虫的最大扩散距离估计为40米，成虫为120 - 130米，导致诱捕面积分别为0.58公顷和4.83 - 5.56公顷。当诱捕器与苹果园边行内的寄主植物一起部署时，成虫的最大扩散距离和诱捕面积分别降至70米和1.67公顷。这些结果表明，褐边绿刺蛾对性信息素刺激的行为反应受寄主植物的影响，并且性诱剂诱捕器的诱捕面积可能会因部署的种植系统而异。外推这些结果时应谨慎，因为在其他作物系统中测量值可能会有所不同。
