Changes in harvesting methods in the early 1990s led to Mahanarva fimbriolata becoming the most prevalent pest in sugarcane plantations. Encouraged by the scarcity of research on the reproductive system and spermatology of Auchenorrhyncha, we provide a detailed description of the male reproductive system and spermatozoa of this cercopid. This will not only aid in taxonomic purposes but also help in understanding the reproductive biology of the species. The male reproductive system, spermatozoa, and sperm bundles of M. fimbriolata were investigated using light microscopy. Our results reveal a reproductive system consisting of a pair of testes, each with 36 follicles, two vasa deferentia, two well-developed seminal vesicles, a single pair of accessory glands, and an ejaculatory duct. Here, we also describe and explore the particularities of the formation of secondary sperm bundles, where cells interestingly bind only to the apical region of the spermatostyle. We also propose some possible benefits of this unusual organization for the reproductive success of the species.

20 世纪 90 年代初收割方法的变化导致甘蔗甘蔗种植园中最常见的害虫为Mahanarva fimbriolata 。受到对Auchenorhyncha的生殖系统和精子学研究稀缺的鼓舞，我们提供了这种鹿科动物的雄性生殖系统和精子的详细描述。这不仅有助于分类学目的，而且有助于了解该物种的生殖生物学。使用光学显微镜研究了M. fimbriolata的雄性生殖系统、精子和精子束。我们的结果揭示了生殖系统由一对睾丸组成，每个睾丸有 36 个卵泡、两个输精管、两个发育良好的精囊、一对附属腺和一个射精管。在这里，我们还描述和探索了次级精子束形成的特殊性，有趣的是，次级精子束的细胞仅与精子柱的顶端区域结合。我们还提出了这种不寻常的组织对于物种繁殖成功的一些可能的好处。
