摘　　要：为探讨蝽科精巢形态差异,以及据此反映的属种间亲缘关系,对蝽科9属13种昆虫精巢进行了观察和比较研究。结果表明,蝽科精巢形态在属内种间具有相对稳定性,属间、亚科间具有差异性。蝽科输精管种间变异大。基于精巢长度、宽度、面积及长宽比的聚类分析结果显示,斑须蝽属Dolycoris、绿蝽属Nezara、茶翅蝽属Halyomorpha关系较近,并与二星蝽属Eysarcoris形成并列关系。菜蝽属Eurydema、麦蝽属Aelia、珠蝽属Rubiconia亲缘关系密切。而果蝽属Carpocoris与条蝽属Graphosoma形成不同分支的特殊进化关系。因此,蝽科精巢可作为属级、亚科级的形态和数值分类特征。In order to explore the morphological differences of testis, and the relationships among the genera in Pentatomidae. We studied 13 species belonging to 9 genera of Pentatomidae. The results showed that the morphology of testis are similar among species in the same genus but different among genera or subfamilies. Dolycoris , Nezara, Halyomorpha and Eysarcoris, Eurydema, Aelia and Rubiconia, Carpocoris and Graphosoma display a close genetic relationship, respectively, based on the cluster analysis of testis length （L）, width （W）, area and L/W of the observed species. Therefore, the morphology of testis in Pentatomidae can be used for genus or subfamily level classification.
