The results showed that the current taxonomic classification of the orders of Diphyllidea, Trypanorhyncha, Pseudophyllidea, Lecanicephalidea and Tetraphyllidea is appropriate and that the morphologic structure of the cestode scolex becomes more and more complicated in the evolution.

使用PAUP4.0b10软件构建的进化树显示，目前关于绦虫二叶目、锥吻目、假叶目、盘头目和四叶目的划分是比较合理的，绦虫进化基本遵循了头节形态从简单到复杂的进化规律。

Sparganum is another generic name of a pseudophyllidean cestode.

The RAPD results illustrate that the phylogenetic relationship betweenBothriocephalid tapeworm parasitic in Grass carpCtenopharyngodon idellus(C.et V.and Common carp(Cyprinus carpio L.)from different regions ofChina is infraspecific with noticeable variance bwtween them.Thephylogenetic trees based on the 3 sequences analyses above are constructed,which show the following relationships:Bothriocephalid tapeworms fromGrass carp,Common carp and Luciobrama are found to be monophyletic,and are very close to Bothriocephalus opsariichthydis,but are divergent toanother monophyletic group comprising Bothriocephalid tapeworms fromZacco,Hemiculter and Leuciscus.On the basis of phylogenetic reconstruction,autapomorphic species conceptis used in species delimitation suitablefor determining four species in the present study:B.acheilognathi,B.opsariichthydis,and two other bothriocephalids parasitic respectively inHemiculter and Leuciscus.It is also deduced that the differentiation time ofBothriocephalid tapeworms parasitic in cyprinids is earlier than that of theirhosts,and the most recent specification happened about one million yearsago.Key words Bothriocephalid tapeworm Molecular Systematics

具体成果有：通过RAPD分析探明了我国不同地理分布的草、鲤鱼头槽绦虫的亲缘关系属于种下水平，并存在较高变异；通过基因合并分析重建头槽绦虫的系统发育关系，表明草鱼、鲤鱼及鯮鱼头槽绦虫是单系群，它们与马口鱼头槽绦虫亲缘关系较近，而与〓条、宽鳍鱲及雅罗鱼头槽绦虫构成的另一单系群亲缘关系较远；在此基础上，提出符合头槽绦虫种的界定的独征物种概念，据此确定鲤科鱼类寄生头槽绦虫的四个种：鱊头槽绦虫，马口鱼头槽绦虫，以及另两种分别寄生于〓条和雅罗鱼的头槽绦虫：根据上述研究推断鲤科鱼类寄生头槽绦虫的分化年代早于其宿主，最近的一次物种形成距今约一百万年左右。

In this experiment,nad4 and cox1 genetic variation of cestodes were firstly studied.Genetic variation and DNA polymorphism of mitochondria were carried out from mitochondrial gene.So the effective genetic markers were found which studied molecular taxonomy and Phylogenetic relationship of cestodes.This study have filled in the blank space of research that was related to China\'s cestodes mitochondrial genome research.

本试验首次对绦虫nad4和cox1基因的遗传变异情况进行研究，从线粒体基因的角度，开展绦虫线粒体遗传变异和DNA多态性方面的研究，找到了研究绦虫分子分类学、种群遗传关系有效的遗传标记，填补了我国寄生绦虫线粒体全基因组相关研究的空白。
