The brown marmorated stink bug, , is a polyphagous pest species of worldwide economic importance. Since the mid-1990s, it has invaded and become established in various countries outside its native Asian range. In the newly invaded areas, biological control by native natural enemies has been shown to be insufficient in the long-term control of this severe pest. Adventive populations of , an important biological control agent of in Asia, have been reported from North America and some European countries since the mid-2010s. This egg parasitoid species seems to follow in the wake of the establishment of populations outside their native Asian range. Here, we report the first discovery of an adventive population of in Germany. In 2020, adult were recovered from parasitized egg masses (naturally laid and sentinel egg masses) and collected in ruderal areas using an insect suction sampler. The arrival of in Germany, unintentional through pathways yet unknown, corroborates a northbound expansion of its range within Europe. Further field surveys will show the extent of its dispersal and establishment capacities within this new distribution area.
棕色入侵 stink 蝽是一种具有全球经济重要性的多食性害虫。自 20 世纪 90 年代中期以来，它已侵入并在其原生亚洲范围以外的各个国家定殖。在新侵入地区，本地天敌的生物防治已被证明在长期控制这种严重害虫方面是不够的。自 2010 年代中期以来，在北美和一些欧洲国家已报告了作为亚洲 重要生物防治剂的 的外来种群。这种卵寄生蜂物种似乎是随着 在其原生亚洲范围以外的种群建立而出现的。在这里，我们报告了在德国首次发现 的外来种群。2020 年，从寄生的 卵块（自然产下的和哨兵卵块）中回收了成年 ，并使用昆虫吸样器在杂草丛生地区收集。 通过尚未知晓的途径无意进入德国，证实了其在欧洲范围内向北的扩张。进一步的实地调查将显示其在这个新分布区域内的扩散和定殖能力的程度。
