印度、越南、中国和日本都有大型刺蝽Agriosphodrus dohrni（Signoret）的记录。它是防治重要农林害虫的潜在生物防治剂之一。据推测，该物种大约在60年前从中国的原生地入侵日本。我们利用线粒体基因COI、Cytb和ND 5片段和核基因EF-1α片段来阐明该菌的入侵历史。dohrni和评估地理事件和相关生态适应对分布格局的影响。A. dohrniin在中国分为三个不同的组，这可能是塑造了早更新世冰期事件和分化的卡拉布里亚阶段。然而，与最近入侵的假设相一致，在日本人群中检测到极低水平的遗传变异，只有两个单倍型的组合线粒体基因。splits网络和ML/BI系统发育树分析均显示，日本的单倍型与中国东部的单倍型的亲缘关系较近。因此，我们假设只有一个引入事件，可能来自中国东部的南京（NJ）和临安（LA）种群。
A large-sized assassin bugAgriosphodrus dohrni(Signoret), has been recorded from India, Vietnam, China and Japan. It is one of the potential biological control agents against some important agricultural and forest pests. This species is speculated to have invaded Japan from its native range in China about 60 years ago. We used three mitochondrial gene fragments (COI,Cytb, andND5) and one nuclear gene fragment (EF-1α) to clarify the invasion history ofA. dohrniand assess the effects of geographic events and associated ecological adaptation on the distribution pattern. The native populations ofA. dohrniin China are divided into three distinct groups, which might be molded by the Early Pleistocene glaciation event and diverged during the Calabrian Stage. However, consistent with the hypothesis of a recent invasion, extremely low level of genetic variation was detected in the Japanese populations, with only two haplotypes for the combined mitochondrial genes. Both the splits network and the ML/BI phylogenetic trees revealed that haplotypes of Japan were more closely-related to those from eastern China. Therefore, we postulate that there has been only one introduction event, probably from somewhere around the Nanjing (NJ) and Lin'an (LA) populations of eastern China.
