Halyomorpha halys is a global invasive species, native to Southeast Asia, that is threatening agriculture in invaded regions. Our objectives were to: 1) establish the attractiveness of semiochemical stimuli paired with field-deployed traps in Europe (Greece, Hungary, Italy, and Switzerland), compared with Maryland, USA, and 2) identify H. halys haplotypes recovered from traps at each location. We found qualitatively identical patterns of capture between sites located across Europe and in Maryland, USA. In both regions, captures of H. halys adults indicated a synergistic response to traps baited with the two component H. halys aggregation pheromone, and pheromone synergist, methyl (2E, 4E, 6Z)-decatrienoate when compared with either individually. Haplotype diversity in Europe based on trapped specimens was much greater than the USA, with five new haplotypes described here, probably indicating ongoing invasion and re-introduction of H. halys. By contrast, a single, previously identified haplotype was trapped in Maryland, USA, representing a single introduction. All H. halys haplotypes responded to each semiochemical in apparent proportion to their frequency in the overall population based on independently derived information from prior work. Taken together, these data suggest that pheromone-based technology will be of global utility for the monitoring of this important invasive species.
褐飞蝽是一种全球入侵物种，原产于东南亚，正在威胁入侵地区的农业。我们的目标是：1）与美国马里兰州相比，确定在欧洲（希腊、匈牙利、意大利和瑞士）与田间部署的诱捕器配对的信息素刺激物的吸引力，以及2）识别从每个地点的诱捕器中回收的褐飞蝽单倍型。我们发现，欧洲各地和美国马里兰州的诱捕地点在捕获模式上具有定性相同的特征。在这两个地区，褐飞蝽成虫的捕获表明，与单独使用相比，用两种成分的褐飞蝽聚集信息素和信息素增效剂（2E, 4E, 6Z）-癸三烯酸甲酯诱捕的诱捕器有协同反应。基于捕获标本的欧洲单倍型多样性远大于美国，这里描述了五个新的单倍型，这可能表明褐飞蝽正在持续入侵和重新引入。相比之下，在美国马里兰州捕获了一个先前确定的单倍型，代表一次单一引入。根据先前工作独立得出的信息，所有褐飞蝽单倍型对每种信息素的反应与其在总体种群中的频率明显成比例。综合来看，这些数据表明基于信息素的技术将在全球范围内用于监测这种重要的入侵物种。
