查询词典 Acrididae

In the second chapter, sequences from the mitochondrial cytochrome b gene were determined for 25 species from the Acrididae and the homologous sequences of 19 species of grasshoppers were downloaded from GenBank. Phylogeny was reconstructed by MP and Bayesian criteria using Yunnanites coriacea and Tagasta marginella as outgroup.

测定了蝗总科25种蝗虫的线粒体Cyt b部分序列，并从GenBank中下载了蝗总科19种昆虫的Cyt b基因同源序列，以瘤锥蝗科的云南蝗Yunnanites coriacea和长额橄蝗 Tagasta marginella作为外群，用MP法和贝叶斯法重建系统发生树。

The dominant species of pests is differential in the various seasons: Macrosiphum avenae and Rhophalsiphum padi is dominant species in spring, Delphacidae and Laphygma exigua is dominant species in summer, Helticus minutus and Acrididae is dominant species in autumn.

在害虫中，不同季节优势种不一样，春季的优势种是麦长管蚜和缢管蚜，夏季的优势种是灰飞虱和甜菜夜蛾，秋季的优势种是黑跳盲蝽和土蝗。

Clade Ⅰ consists of the species of Pyrgomorphidae and Chrotogonidae, Clade Ⅱ consists of the species of Pneumoridae, Clade Ⅲ consist of species of Pamphagidae and Clade Ⅳ contains species of Catantopidae, Oedipodidae, Arcypteridae, Gomphoceridae and Acrididae.

三、在对斑翅蝗科系统发育的研究中，我们共测定了斑翅蝗科4亚科15种蝗虫的16S rDNA序列片段，并从GenBank中下载了斑翅蝗科6种、其它蝗科9种的16S rDNA相应序列片段，然后对这共计30种蝗总科昆虫的16S rDNA序列片段进行了同

In conclusion: Thirteen types of antennal sensilla were find in eight species of Acrididae:trichoid sensilla, chaetic sensilla, basiconic sensilla, coeloconicsensilla, cavity sensilla, Bohm bristles, sporangium sensilla.

实验结果表明：剑角蝗科8种蝗虫的触角有13种感受器类型：毛形感受器、刺形感受器、锥形感受器、腔锥形感受器、腔形感受器、Bohm氏鬃毛、芽孢形感受器。

The members of the same genus and family were grouped together. The polyogenetic relationships of 8 families were Pyrgomorphidae →Chrotogonidae→Pamphagidae→Oedipodidae→Acrididae→Arcypteridae→Gomphoceridae→Cantantopidae.Pygomorphidae had closer relationships with Chrotogonidae as well as being the most ancestral group. Arcypteridae and Gomphoceridae were the sister groups and had closer relationships with most evolutionary Catantopidae. Tridactylidae was divided firstly as a suborder,which differs from the recent taxonomy distinctly. Haglidae and Gryllidae were grouped into suborder Ensifera, Tetrigidae and 8 families of Acridoidea were grouped into suborder Caelifera, as same as recent taxonomy.

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；哈螽科和蟋蟀科聚在一起为剑瓣亚目，蚱科和蝗总科的8科组成短瓣亚目，同现用的分类系统。

The Acridoidea is generally divided into 8 families by Chinese scholars, Pamphagidae, Chrotogonidae, Pyrgomorphidae, Catantopidae, Acrididae, Oedipodidae, Arcypteridae, Gomphoceridae.

我国分类学家通常把中国蝗总科分为8个科：癞蝗科、瘤锥蝗科、锥头蝗科、斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科。
