摘    要:迄今,蝗科内各分类阶元之间的系统发生关系大部分是未知的。本文用来自中国24种蝗科昆虫的12SrDNA和16SrDNA2个基因的联合序列(共795bp)数据,以锥头蝗科的锥头蝗(Pyrgomorpha conica)为外群,重建了分子系统树。研究结果表明,在12SrDNA与16SrDNA组成的联合数据中,转换的替代速率明显比颠换的替代速率高得多,核酸的替代已经发生了饱和。分子系统树表明:斑翅蝗亚科是一单系群,该亚科是一个合法的亚科,但斑腿蝗亚科和蝗亚科都不是单系群;斑翅蝗亚科在蝗科内是一个相对原始的类群,而稻蝗亚科比斑翅蝗亚科相对进化,比蝗科的其他亚科的种类相对原始。

关 键 词:系统发育  蝗科

Abstract:The phylogenetic relationships among all taxa within the Acrididae (Orthoptera: Acridoidea) were largely unknown until now. In this study, to further investigations, 24 species of Acrididae from China were used as sample taxa. The sequence constitutions and variations were analyzed and the molecular phylogenetic trees were reconstructed based on the combined sequence data (795 bp length in total) of 12S rDNA and 16S rDNA, using the grasshopper Pyrgomorpha conica of Pyrgomorphidae as the outgroup. The results showed that the rates of the two kinds of transitions are obviously much higher than that of the four kinds of transversions in these combined 12S 16S rDNA sequence data. The saturation of nucleotide substitutions happened in 12S and 16S rDNA sequence data. The molecular phylogenetic trees indicated that Oedipodinae is a monophyletic group and this subfamily is a natural one, but Catantopinae and Acridinae are non-monophyletic. Oedipodnae is a relatively primitive group within the Acrididae, whereas the Oxyinae may have diverged later than Oedipodinae, but earlier than most other species of Acridide.
Keywords:16SrDNA  12SrDNA  Phylogeny  Acrididae  16S rDNA  12S rDNA
