In this present study, the mitochondrial DNA gene cytochrome coxidase subunit I (COI) and the small subunit ribosomal RNA (18S rDNA) gene were used to determine the taxonomic relationships of Psoroptes and Chorioptes mites from China. The neighbor-joining and maximum-parasimony approach were used to evaluate the evolutionary relatedness among different hosts in the genera Psoroptes and Chorioptes. Phylogenetic analysis showed that Psoroptes cuniculi and Psoroptes natalensis may be two different species within the genus Psoroptes, and Chorioptes texanus and Chorioptes panda are different species within the genus Chorioptes.
在本研究中，使用线粒体 DNA 基因细胞色素 coxidase 亚基 I（COI）和小亚基核糖体 RNA（18S rDNA）基因来确定来自中国的 Psoroptes 和 Chorioptes 螨的分类关系。使用邻接法和最大简约法评估 Psoroptes 和 Chorioptes 属中不同宿主之间的进化亲缘关系。系统发育分析表明，兔痒螨和南非痒螨可能是 Psoroptes 属中的两个不同种，而 Texas 恙螨和大熊猫恙螨是 Chorioptes 属中的两个不同种。
