The aphid tribe Macrosiphini Wilson, 1910 (Hemiptera: Aphididae: Aphidinae) is one of the most controversial groups within Aphididae. We sequenced 2876 bp from one nuclear gene (EF-1α) and four mitochondrial genes (COI, tRNA + COII, 16S) from 107 terminal taxa representing 57 genera of Macrosiphini s.l. (the former Macrosiphini + genera in former Pterocommatini), including all of the recognized major genera and outgroups, and reconstructed the phylogeny using maximum likelihood, maximum parsimony and Bayesian methods. The stepping-stone method was used to evaluate various topological hypotheses regarding Macrosiphini s.l. and related groups. Our findings support both the monophyly of Macrosiphini s.l., and of two subordinate groups (Macrosiphini s.str and the Pterocomma-group), as well as the transfer of Capitophorus, Pleotrichophorus, Liosomaphis and Vesiculaphis to the Pterocomma-group-a result not previously suggested by analyses of molecular data. Ancestral state reconstructions for Macrosiphini and the Pterocomma-group suggest an ancestral primary host association with Rosales and Malpighiales, respectively, and other host associations within the tribe. Host transitions independently occurred more than once in Macrosiphini s.str. Furthermore, host-shifts between Rosales and Malpighiales may have occurred at least once in the Pterocomma-group. Additionally, the Macrosiphini phylogeny indicates that host associations are consistent also with host ecology, with a partitioning of aphid-host relationships into riparian and periaquatic habitats versus drier forest/shrubland habitats.
麦长管蚜族(Macrosiphini Wilson,1910)(半翅目:蚜科:蚜亚科)是蚜科中最具争议的群体之一。我们从代表麦长管蚜族(包括前麦长管蚜族和前 Pterocommatini 属的 57 个属的 107 个末端分类群)的 107 个分类群中,获得了 2876bp 的核基因(EF-1α)和四个线粒体基因(COI、tRNA+COII、16S),并使用最大似然法、最大简约法和贝叶斯法重建了系统发育。使用踏脚石法评估了有关麦长管蚜族和相关类群的各种拓扑假说。我们的研究结果支持了麦长管蚜族的单系性,以及两个亚群(麦长管蚜族和 Pterocomma 族)的单系性,以及 Capitophorus、Pleotrichophorus、Liosomaphis 和 Vesiculaphis 属转移到 Pterocomma 族的结果——这一结果以前没有通过分子数据分析得到提示。麦长管蚜族和 Pterocomma 族的祖先状态重建表明,其原始的主要宿主与蔷薇目和大戟目相关,而该族内的其他宿主关联。麦长管蚜族的多次独立的宿主转移发生在麦长管蚜族内。此外,Pterocomma 族中蔷薇目和大戟目之间的宿主转移可能至少发生过一次。此外,麦长管蚜族的系统发育还表明,宿主关系也与宿主生态一致,将蚜虫与宿主的关系划分为滨水和近水栖息地与较干燥的森林/灌丛栖息地。
