摘　　要：球鼠妇(Armadillidium vulgare Latreille)、多霜腊鼠妇(Porcellionides pruinosus Brandt)和光滑鼠妇(Porcellio leavis Latreille)是等足目(Isopoda)动物中不同属的种类。试验分别测定了这三种鼠妇两性之间的体重、体长、体宽、体高、体长/体宽、体长/体高、体宽/体高的数值,统计分析了每种鼠妇两性之间的差异。结果表明,两性球鼠妇差异显著,两性多霜腊鼠妇有一定的差异,两性光滑鼠妇差异不显著。该结果提示等足类动物的两性异型存在多样性。Armadillidium vulgare Latreille,Porcellionides pruinosus Brandt and Porcellio leavis Latreille are three species belong to various genus in Isopoda.The body weight,length,width,height,length/width,length/height and width/height of them were tested in this study;and the differences between sexes of each species were compared respectively.The results showed that the differences between sexes were significant in A.vulgare,less significant in P.pruinosus and in significant in P.leavis.It suggested that the sexual size dimorphism in isopodan species is diversity.
