在北美，有一个形态上确定的蚜虫物种群，它们以山茱萸属植物为主要寄主植物，并且与蜂科植物有关。我们将它们统称为asclepiadis种群，并试图利用线粒体细胞色素氧化酶1 （Cox1）和核延伸因子1-α (EF1α1)基因序列来阐明其成员的分类地位。对这两个基因组合数据的贝叶斯系统发育分析有力地支持了a . asclepiadis种群组成的进化支。这一组包括以下的北美本土物种：A. asclepiadis， A. carduella， A。纵翅拟虫、不耐拟虫、新吉拟虫、黑斑拟虫、桑斑拟虫、塔斯皮拟虫和振翅拟虫，以及与之相关的外来种水蛭拟虫。贝叶斯系统发育网络和最大简约网络嵌套了所有符合asclepiadis和carduella以及A. nigratibialis诊断特征的集合。Cox1和EF1α1在asclepiadis和carduella采集间的对向距离分别为0.00-0.73和0.00-0.87%。因此，我们得出结论，a . asclepiadis Fitch 1851是a . carduella Walsh 1863, syn11 .的高级同义。此外，所有形态鉴定为a . impatientis的物种序列几乎100%匹配。生物学研究表明，凤仙花蚜虫是一种介于凤仙花和山茱萸之间的杂交种。我们还发现两性形态的形态学特征有助于区分以山茱萸为主要寄主植物的物种。
In North America, there is a morphologically defined group of Aphis species that use Cornus spp. as primary host plants and also are associated with plants in the family Apiaceae. We refer to them collectively as the Aphis asclepiadis species group and attempt to elucidate the taxonomic status of its members using sequences of mitochondrial cytochrome oxidase 1 ( Cox1 ) and nuclear elongation factor 1-α ( EF1α1 ) genes. The Bayesian phylogenetic analyses of the combined data of these two genes strongly supported a clade composed of the A. asclepiadis species group. This group includes the following North American native species: A. asclepiadis , A. carduella , A . decepta , A. impatientis , A. neogillettei , A. nigratibialis , A. saniculae , A. thaspii , and A. viburniphila , and the related exotic species, A. salicariae . Bayesian phylogenetic and Maximum Parsimony Network nested all the collections that match the diagnostic characters described for A. asclepiadis and A. carduella , and the ones described for A. nigratibialis . Moreover, the range of pair-wise distances between collections of A. asclepiadis and A. carduella are 0.00–0.73 and 0.00–0.87% for Cox1 and EF1α1 , respectively. Therefore, we conclude that A. asclepiadis Fitch 1851 is a senior synonym of A. carduella Walsh 1863, syn. nov. In addition, all the sequences of species morphologically identified as A. impatientis matched almost 100%. Biological studies showed that Aphis impatientis is a heteroecious species that alternates between Cornus and Impatiens . We also found that morphological characterization of the sexual morph is useful to differentiate species that feed on Cornus spp. as primary host plants.
