摘  要:
简要概述了线粒体基因组的结构和特点,同时基于线粒体基因组中的13个蛋白编码基因,选螳螂目、蜚蠊目、等翅目及螳目的5个种为外群,对直翅目34个种进行系统发育学研究。结果表明直翅目与外群分开,形成单系群。直翅目内部形成螽亚目与蝗亚目2个单系群。在螽亚目内部形成螽次亚目与蟀次亚目2个分支,且驼螽总科与螽斯总科形成姐妹群,但蚁蟋科与蝼蛄科形成1支,并不支持蟋蟀总科的单系性。在蝗亚目内部形成(蚤蝼总科+(牛蝗总科+(锥头蝗总科+蝗总科)))的系统进化关系。

摘  要:
The Orthoptera,belonging to the Arthropoda,is one of the largest orders among the Insecta.Mitochondrial DNA has been widely used in insect phylogenetic studies and proved to be an efficient maker in this field.This paper introduces the structure and characters of the mitochondrial genome.The phylogenetic relationships of 34 species from Orthoptera and 5 outgroup species(Mantodea,Blattaria,Isoptera,and Mantophasmatodea) were performed based on the 13 mitochondrial protein-coding genes.The monophyly of the Orthoptera is strongly supported,with its two suborders,Caelifera and Ensifera,being recovered as monophyletic respectively.Within Ensifera,it is subdivided into Grylloidea and Tettigonioidea.The superfamily of Rhaphidophoridae is a sister group to Tettigoniidae.The monophyly of Grylloidea is not recovered because Myrmecophilidae and Gryllotalpidae cluster together.The system evolution relationship of the superfamilies within Caelifera is formed(Tridactyloidea+(Pneumoridea+(Pyrgomorphoidea+Acridoidea))).
