Study on comparative morphology of male reproductive system of three planthoppers (Hemiptera:Fulgoroidea) | 3种蜡蝉雄性生殖系统形态比较(半翅目：蜡蝉总科)

chinois. 研究蜡蝉雄性生殖系统的整体结构，以发现更多的分类特征，为其所属类群乃至蜡蝉总科的分类及系统发育研究提供依据。在Leica MZ125解剖镜下，对缘蛾蜡蝉（Salurnis marginella(Guérin-Meneville)）、八点广翅蜡蝉（Ricania speculum(Walker)）及斑衣蜡蝉（Lycorma delicatula (White)） 3种蜡蝉的雄性生殖系统进行解剖观察，应用QImaging Retica 2000R CCD数码相机进行照相，并对3种蜡蝉的雄性内生殖器官进行比较研究。3种蜡蝉的雄性生殖系统的形态结构基本一致，射精管端部膨大，生殖附腺发达，但每侧精巢内精巢小管的数目因种类不同而具明显差异，八点广翅蜡蝉12根，缘蛾蜡蝉和斑衣蜡蝉均为6根；八点广翅蜡蝉和斑衣蜡蝉的贮精囊外周被以薄膜，而缘蛾蜡蝉的贮精囊则无薄膜包被。缘蛾蜡蝉与八点广翅蜡蝉的雄性生殖系统结构较为相似，其2个精巢相互分开，而斑衣蜡蝉的2个精巢相向包被在同一薄膜之中，这表明雄性生殖系统在蜡蝉总科系统学研究中具有重要的应用价值。

anglais. The male internal reproductive system of planthoppers is studied and illustrated in this research, aiming at providing more useful information for taxonomy and phylogeny of Fulgoroidea. The male internal reproductive organs of three planthoppers (Salurnis marginella (Guérin-Meneville) of the Flati-dae, Ricania speculum (Walker) of the Ricaniidae and Lycorma delicatula (White) of the Fulgoridae) are dissected by the stereomicroscope of Leica MZ125 and photoggrahed by the QImaging Retica 2000R CCD. Then they are compared and researched. The results show that the form and structure of male reproductive system of these three planthoppers are similar to each other, the ejaculatory duct is distinctly inflated near terminal and the accessory gland is well-developed, and the number of follicles distinctly varies in different species, R. speculum has 12 follicles, both S. marginella and L. delicatula have 6 follicles. In addition, the seminal vesicle of R. speculum and L. delicatula are sheathed by membrane, but S. marginella is not. Generally, the testis of S. marginella and R. speculum are clearly separated from each other, but that of L. delicatula are enclosed by the same membrane sheath. It shows male reproductive system of planthopper provides meaningful information in the systematic research of Fulgoroidea.
