We studied the ectoparasite and the Amblyopinini beetle fauna associated with four small mammal species of the Atlantic Rainforest of Ilha Grande, an island located off the southern Rio de Janeiro State Coast, Southeastern Brazil, analyzing to what extent the parasites were specific to each region of the host body. During the study, a total of 90 individual rodents were captured: 61 Proechimys iheringi Thomas, 1911 (Echymyidae), 22 Sciurus aestuans (Thomas, 1901) (Sciuridae), 4 Oxymycterus sp. (Waterhouse, 1837), and 2 Nectomys squamipes (Brants, 1827) (Sigmodontinae). The data showed that the ectoparasites and Amblyopinini on some rodent hosts in Ilha Grande tend to prefer particular host body sites, and that some ectoparasite species sites may overlap owing to their inaccessibility to the host.
我们研究了与巴西东南部里约热内卢州南部海岸外的一个岛屿——大岛大西洋雨林中的四种小型哺乳动物相关的体外寄生虫和隐翅虫科甲虫动物群，分析了寄生虫对宿主体表各区域的特异性程度。在研究过程中，共捕获了90只个体啮齿动物：61只托马斯倭鼠（1911年，托马斯命名，鼠科）、22只热松鼠（1901年，托马斯命名，松鼠科）、4只奥氏鼠属（1837年，沃特豪斯命名）和2只鳞足水鼠（1827年，布兰特斯命名，稻鼠亚科）。数据表明，大岛某些啮齿动物宿主身上的体外寄生虫和隐翅虫科甲虫倾向于偏好特定的宿主体表部位，并且由于宿主难以触及某些体外寄生虫物种的寄生部位，这些部位可能会重叠。
