苹果螺（瓶螺科：自1980年左右引入以来，原产于新大陆的福寿螺（Pomacea）已成为南亚和东亚广泛的农业和环境害虫。虽然它们的影响已被广泛记录，但关于它们的身份和地理起源仍然存在相当大的混乱。解决混淆的努力受到了来自本地和引进范围的分类和地理采样不足的影响。使用系统发育和系谱学的方法，我们分析了610-655 bp的细胞色素c氧化酶亚基I的DNA序列从783个苹果蜗牛从164个亚洲的位置和57个本地南美的位置。在亚洲，我们发现了两个分支中的四种福寿螺：（1）福寿螺和P. insularum，（2）P. scalaris和P. diffusa。简约网络和失配分布表明，两个最广泛的物种，P. canaliculata和P. insularum的非本地范围，可能是由于多次引进。分子分析与早期的记录一致;非本地的P. canaliculata种群可以追溯到阿根廷的多个地点，并且可能已经被引入了不止一次。相反，P. insularum可能是从巴西和阿根廷独立引进的。多次引进可能部分解释了这两个物种的成功和快速传播。与P. canaliculata和P. insularum不同，P. scalaris和P. diffusa可能是通过水族馆贸易引入的，分别来自阿根廷和巴西。这四个物种之间可能的生理，生态和本地范围的差异突出了准确识别的重要性，在了解入侵模式和过程，这是至关重要的，在制定和实施管理策略。
Apple snails (Ampullariidae: Pomacea) native to the New World have become agricultural and environmental pests widely in southern and eastern Asia since their introduction in about 1980. Although their impacts have been extensively documented, considerable confusion persists regarding their identities and geographical origins. Efforts to resolve the confusion have suffered from inadequate taxonomic and geographical sampling from both native and introduced ranges. Using phylogenetic and genealogical methods, we analysed 610-655 bp of cytochrome c oxidase subunit I DNA sequences from 783 apple snails from 164 Asian locations and 57 native South American locations. In Asia, we found four species of Pomacea in two clades: (1) Pomacea canaliculata and P. insularum, and (2) P. scalaris and P. diffusa. Parsimony networks and mismatch distributions indicate that the non-native ranges of the two most widespread species, P. canaliculata and P. insularum, probably result from multiple introductions. Molecular analyses are consistent with early accounts; non-native P. canaliculata populations trace back to multiple locations in Argentina and have probably been introduced more than once. In contrast, P. insularum was probably introduced from Brazil and Argentina independently. Multiple introductions may, in part, explain the success and rapid spread of these two species. Unlike P. canaliculata and P. insularum, P. scalaris and P. diffusa were probably introduced through the aquarium trade, derived originally from Argentina and Brazil, respectively. Possible physiological, ecological, and native range differences among these four species highlight the importance of accurate identification in understanding invasion patterns and processes, which is vital in developing and implementing management strategies.
