在过去的十几年里，人们投入了大量的精力来阐明胎生蚜虫（Aphididae）的高级系统发育关系。然而，迄今为止，仍然没有普遍接受的系统发育假说。在这项研究中，我们基于 35 种蚜虫的线粒体基因组序列（其中 22 种是新报道的），为蚜科建立了强大的系统发育框架。使用多个数据集、替代分区方案和不同的基于模型的方法进行系统发育推断。我们的分析结果为蚜虫主要谱系提供了良好支持的主干关系，表明线粒体基因组数据解决蚜虫系统发育问题的可行性。 Mindarinae 被强烈支持为蚜科中最早的分支谱系。由 Calaphidinae、Phyllappidinae 和 Saltusaphidinae 组成的单系支被证实是物种最丰富的蚜亚科 (Aphidinae) 的姐妹群。此外，形态学上定义的 Eriosomatinae 亚科被发现是非单系的。
Over the past dozen years, considerable effort has been devoted to unravelling the higher-level phylogenetic relationships of viviparous aphids (Aphididae). However, to date, there is still no commonly accepted phylogenetic hypothesis. In this study, we establish a robust phylogenetic framework for the Aphididae based on mitochondrial genome sequences of 35 aphid species, 22 of which are newly reported. Phylogenetic inferences are performed using multiple data sets, alternative partitioning schemes and different model-based methods. Our analyses result in well-supported backbone relationships for the major lineages of aphids, suggesting the feasibility of mitogenome data for resolving phylogenetic questions in aphids. Mindarinae is strongly supported as the earliest branching lineage within Aphididae. A monophyletic clade comprising Calaphidinae, Phyllaphidinae and Saltusaphidinae is corroborated to be the sister group to the species-richest subfamily Aphidinae. In addition, the morphologically defined subfamily Eriosomatinae is uncovered to be non-monophyletic.
