河北白洋淀鱼类寄生小车轮虫属和三分虫属分类学研究

A Taxonomic Study on Genera Trichodinella and Tripartiella from the Fish in Baiyangdian Lake,Hebei Province

2009年4月～2010年10月每月中旬从河北白洋淀采集鱼类,对寄生的隶属车轮虫科的小车轮虫属和三分虫属进行分类与鉴定。应用干银染色法以显示车轮虫的附着盘结构,活体吉姆萨染色方法以显示细胞核形态结构,采用"统一特定方法"和"齿体定位描述法"鉴定出小车轮虫属(Trichodinella)3种,分别为周丛小车轮虫(T.epizootica)、纤细小车轮虫(T.subtilis)和卡普小车轮虫(T.carpi)。鉴定出三分虫属(Tripartiella)2种,分别为鳞三分虫(T.bulosa)和大型三分虫(T.macrosoma)。中华鳑鮍(Rhodeus sinensis)是卡普小车轮虫的新宿主记录,麦穗鱼(Pseudorasbora parva)和圆尾斗鱼(Macropodus ocellatus)是鳞三分虫的新宿主记录,白鲦(Hemiculter leucisculus)是大型三分虫的新宿主记录。

A taxonomic study on genera Trichodinella Srame-Husek and Tripartiella Lom from the fish in Baiyangdian Lake,Hebei province was carried out.The samplings were done at the midest of each month from April,2009 to October,2010.Dry silver impregnation method was used to show the adhesive disc of the Trichiodinalla and Giemsa staining method was used to show the shape and structure of the living organism＇s nuclear.The Trichiodinalla were identified using the methods of ＂uniform specific characteristics＂ and ＂description of denticle elements＂.Identification results were as followings,three species of genus Trichodinella,namely T.epizootica,T.subtilis,T.carpi,were identified.Two species of genus Tripartiella,namely T.bulosa,T.macrosoma,were identifed.Rhodeus sinensis was firstly recorded as the host of T.carpi.Pseudorasbora parva and Macropodus ocellatus were firstly recorded hosts as the of T.bulosa.Hemiculter bleekeri was firstly recorded as the host of T.macrosoma.
