查询词典 Acrididae

In the first chapter, using fragments of COI gene, we studied the phylogenetic relationships among species of five familes of Acridoidea with MP and Bayesian methods. The results were as follows:(1) Species of Acrididae, Gomphoceridae and all the Arcypterinae species of Arcypteridae are monophyletic. Species of Oedipodidae are supported as a monophyleticgroup, Ceracrinae species of Arcypteridae cluter together to make a monophyletic group. Epistaurus aberrans and Xenocatantops humilis is a phylogenetic group, Stenocatantops splendens and Hieroglyphus banian is also a phylogenetic group.

我们首先利用COI基因序列片段，使用最大简约法、贝叶斯法研究了斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科5个科42种的系统发育关系，得到如下结果：（1）由所有网翅蝗亚科的物种与剑角蝗科绿洲蝗亚科和槌角蝗科的物种组成一个单系群；斑翅蝗科的物种组成一个单系群；网翅蝗科的竹蝗亚科的黄脊雷蓖蝗和青脊竹蝗聚在一起形成单系群；斑腿蝗科的长翅十字蝗和大斑外斑腿蝗亲缘关系较近，形成一个单系群；长角直斑腿蝗和等歧蔗蝗始终聚在一起，形成一个单系群。

The phylogenetic relationships among all taxa within the Acrididae (Orthoptera: Acridoidea) were largely unknown until now.

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。

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.

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。

Any of numerous grasshoppers of the family Acrididae, often migrating in immense swarms that devour vegetation and crops.

蝗虫蝗科的一种蝗虫，经常大批迁徙，将所到之地所有植物和庄稼吃光

Any of numerous grasshopper s of the family Acrididae,often migrating in immense swarms that devour vegetation and crops.

蝗虫蝗科的一种蝗虫，经常大批迁徙，将所到之地所有植物和庄稼吃光

Any of numerous grasshoppers of the family Acrididae,often migrating in immense swarm s that devour vegetation and crops.

蝗虫蝗科的一种蝗虫，经常大批迁徙，将所到之地所有植物和庄稼吃光

Any of numerous grasshoppers of the family Acrididae,often migrat in g in immense swarms that devour vegetation and crops.

蝗虫蝗科的一种蝗虫，经常大批迁徙，将所到之地所有植物和庄稼吃光

The relationships among the five families are very close, so we support the view that these five families can be combined into one family Acrididae.(3) It is suggested that Arcypterinae, Gomphoceridae and Chrysochraontinae be combined into Gomphocerinae of the family Acrididae.

在与我国传统分类和国外分类系统比较基础上，结合我们的系统树，建议将网翅蝗亚科、槌角蝗科和绿洲蝗亚科合并，恢复国际用名大足蝗亚科Gomphocerinae。

The taxonomic system is very different from the one used widespreadly by foreign scholars. The taxonomic status and the phylogentic relationships among the five families Catantopidae, Acrididae, Oedipodidae, Arcypteridae, Gomphoceridae is the main controversy. In order to provide enough proofs for improving the taxonomic system, it is necessary to study the phylogeny of five families of Acridoidea based on molecular markers.

但此分类系统与国外所用的分类系统差别较大，争论的焦点在于斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科5个科的分类地位及其相互关系，因此我们从分子水平上探讨这5科的系统发育关系，为完善蝗总科分类系统提供一些必要的证据。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
