| 摘 要： | 应用核型似近系数聚类分析方法，研究了小稻蝗Oxya hyla intricata、山稻蝗O.Agav-isa、上海稻蝗O.Shanghaiensis无齿稻蝗O.Adentata、中华稻蝗O.Chisensis、日本稻蝗O.Japonica、短额负蝗Atractomorpha sinensis、奇异负蝗A.Pergrina和日本蚱Tetrix japonica等9种蝗虫的亲缘关系。结果显示，9种蝗虫分为3类：稻蝗，负蝗和蚱。6种稻蝗之间的核型似近系数(λ)在0.961～0.5695之间，2种负蝗的λ＝0.5867，日本蚱与这8种蝗虫的λ在0.5318～.0322。聚类图直观地反映出它们的亲缘关系与形态分类学的分类结果相一致。从9种蝗虫 的核型演化上看，日本蚱是较原始的类型，负蝗分化也较早，而稻蝗则是较进化的类型。 |

| Abstract: | By applying cluster analysis of karyotype resemblance-near coefficientsλ), we have studied the phylogenetic relation of Oxcya hyla intricata, O. agavisa, O.Shanghaiensis , O. adentata , O. chisensis , O. japonica, Atractomorpha sinensis , A. pergrinaand Tetrix japonica. Results show that the 9 locust species can be roughly divided into three categories: Oxya, Atractomorpha and Tetrix. For the 60xya species, their karyotype resemblance-near coefficients (λ,) range from 0.9610 to 0.5695. For the two Atractomorpha, the 3. Is 0.5867. For T. Japonica and the other locusts it ranges from0.5318 to 0.0322. The cluster figure reflects objectively that they are consistent to their phylogenetic relation and the result of the morphological systematics. From the evolution of the karyotypes of the 9 locust species, we consider that Tetrix japonica is themost ancient type, Atractomorpha is also of early differentiation and Oxay is of the most recent evolutional type. |
