蝗总科部分种类16S rDNA的分子系统发育关系

将自测的我国直翅目蝗总科8科8个种和从互联网GenBank中检索到相关物种的线粒体基因组：16S rDNA序列片段进行同源性比较,计算核苷酸使用频率,并构建分子系统树。在获得的480bp的序列中。A T约占70．7％,G C为29．3％,颠换取代(transversion)的速率大于或接近转换取代(transition)的速率,其中188个核苷酸位点存在变异。研究结果表明：在直翅目蝗总科有差异的188bp中,属内种间的碱基序列差异仅为1．5％,科内属间为3．5％～3．6％,科间差异为4．8％～15．8％,亚目间差异达到15．2％～25．6％。分子系统树表明：科内的属和属内的种均优先聚在一起;蝗总科8科的起源关系为：锥头蝗科→瘤锥蝗科→癞蝗科→斑翅蝗科→剑角蝗科→网翅蝗科和槌角蝗科→斑腿蝗科;锥头蝗科与瘤锥蝗科关系较近,是蝗总科内最原始的类群;槌角蝗科和网翅蝗科互为姐妹群,与最进化的斑腿蝗科关系较近;蚤蝼科为独立的一支,最先分出,似为一个亚目,与现用的分类系统有明显差别;哈螽科(螽嘶总科)和蟋蟀科聚在一起为剑瓣亚目(Ensifera),蚱科和蝗总科的8科组成短瓣亚目(Caehfera),同现用的分类系统。     

Phylogenetic analyses of some genera in Oedipodidae （Orthoptera： Acridoidea） based on 16S mitochondrial partial gene sequences

Basedonthe 16S mitochondrial partial gene sequences of 29 genera, containing 26 from Oedipodidae and one each from Tanaoceridae, Pyrgomorphidae and Tetrigidae （as outgroups）, the homologus sequences were compared and phylogenetic analyses were performed. A phylogenetic tree was inferred by neighbor-joining （N J）. The results of sequences compared show that： （i） in a total of 574 bp of Oedipodidae, the number of substituted nucleotides was 265 bp and the average percentages ofT, C, A and G were 38.3%, 11.4%, 31.8% and 18.5%, respectively, and the content of A＋T （70.1%） was distinctly richer than that of C＋G （29.9%）; and （ii） the average nucleotide divergence of 16S rDNA sequences among genera of Oedipodidae were 9.0%, among families of Acridoidea were 17.0%, and between superfamilies （Tetrigoidea and Acridoidea） were 23.9%, respectively. The phylogenetic tree indicated： （i） the Oedipodidae was a monophyletic group, which suggested that the taxonomic status of this family was confirmed; （ii） the genus Heteropternis separated from the other Oedipodids first and had another unique sound-producing structure in morphology, which is the type-genus of subfamily Heteropterninae; and （iii） the relative intergeneric relationship within the same continent was closer than that of different continents, and between the Eurasian genera and the African genera, was closer than that between Eurasians and Americans.

新疆蝗总科区系研究

新疆现有蝗虫１５７种,它们分别隶属于８科６２属。在１５７种蝗虫中,古北种占绝对优势,有１２０种,其次为特有种,有３５种,广布种甚少,仅２种。在古北种中,中亚种最多,其次为泛古北种,而欧洲西伯利亚种、地中海种和东北种均很少。在８个科中,泛古北种在网翅蝗科中占优势,中亚种在班翅蝗科中占优势,斑腿蝗科在蝗总科中是相当大的一个科,在我国也占有很大优势,但在新疆其属种数量却很少。
