海南岛小兽类寄生蜱的群落结构

Community Structure of Ticks Parasitic on Small Mammals From Hainan China

摘要: 本文定量研究了海南岛三亚市9种小兽类体外寄生蜱的群落结构。共发现8种寄生蜱，粒形硬蜱的宿主范围广，在所捕获的9种小兽类体外均有寄生。珀氏长吻松鼠体表粒形硬蜱的带蜱率最高(76.92%)。钝刺血蜱和长须血蜱普遍寄生于社鼠、白腹鼠和屋顶鼠体外，其带蜱率相当高(>50%)。社鼠和海南毛猬的多样性指数低。

Abstract: Community structures of the ticks parasitic on 9 species of small mammals obtained from Hainan were studied.Ixodes granulatus parasitized on all the hosts.Rate of I.granulatus on Dremomys pernyi was the highest (76.92 percent).Haemaphysalis aponommoides and H.doenitze commonly parasitized on Rattus coxingi,R.niviventer and R.rattus and the rate of infestation was relativeley high (more than 50 per.).he diversity indices of R.niviventer and Neophylomys hainanensis were lower.
