福寿螺，俗称苹果螺，原产于南美洲，自20世纪80年代引入以来，已成为中国南方广泛分布的农业和环境害虫。然而，直到2010年，研究人员才认识到中国至少存在两种：P. canaliculata 和 P. maculata。尽管苹果螺的影响已被广泛记录，但对该物种在中国目前的分布和起源仍然存在困惑。为了解决这个困惑，我们使用系统发育和系统发育地理学方法分析了 1464 个线粒体 COI 序列，其中包括来自中国南方收集的样本的 349 个新序列和来自本地和引入范围内收集的蜗牛的 1115 个公开序列。所有采样点均发现了 Pomacea canaliculata，而仅在四川盆地和浙江省的 5 个采样点发现了 P. maculata。我们的数据表明，中国的 P. canaliculata 种群具有阿根廷起源，这与该物种在亚洲其他地方的多次引入一致。此外，在中国仅建立了一个 P. maculata 谱系，与巴西种群共享。
Species of Pomacea, commonly known as apple snails, are native to South America, and have become widely distributed agricultural and environmental pests in southern China since their introduction in the 1980s. However, only since 2010 have researchers recognized that at least two species, P. canaliculata and P. maculata, are present in China. Although impacts of apple snails have been extensively documented, confusion still persists regarding current distributions and origin of the species in China. To resolve this confusion, we used phylogenetic and phylogeographic methods to analyze 1464 mitochondrial COI sequences, including 349 new sequences from samples collected in southern China and 1115 publicly available sequences from snails collected in the native and introduced ranges. Pomacea canaliculata was found at all sampled localities, while P. maculata was found at only five sampled localities in the Sichuan basin and Zhejiang province. Our data indicate that Chinese populations of P. canaliculata share an Argentinian origin, consistent with multiple introductions of this species elsewhere in Asia. In addition, just a single lineage of P. maculata is established in China, which shares with populations in Brazil.
