A cross-sectional survey of ticks infesting sheep was conducted in Sennar State, Sudan. A total body collection of ticks was carried out at five localities Sennar town, Singa, Dinder, Abu Naama and Um Banein on two types of Desert sheep (Watish and Ashgar) on two farms at each locality at two monthly intervals for one year starting July 2002 to May 2003. Four tick genera and eight species were identified. They were Amblyomma lepidum, Hyalomma anatolicum anatolicum, Hyalomma truncatum, Rhipicephalus (Boophilus) decoloratus, Rhipicephalus camicasi, Rhipicephalus evertsi evertsi, Rhipicephalus guilhoni and Rhipicephalus muhsamae. A significant (P < or = 0.05) seasonal pattern of activity was observed for A. lepidum and R. guilhoni with peak activity occurring during rainy seasons. The highest mean number of ticks (7.26 +/- 0.58) was recorded at Abu Naama, while the lowest mean (3.61 +/- 0.31) was recorded in Sennar. Watish type sheep carried significantly (P < or = 0.05) more ticks than Ashgar type.
在苏丹森纳尔州对寄生在绵羊身上的蜱虫进行了一项横断面调查。从2002年7月至2003年5月，为期一年，每隔两个月在森纳尔州的五个地点（森纳尔镇、辛加、丁德、阿布纳马和乌姆巴奈因）的两个农场，对两种沙漠绵羊（瓦蒂什和阿什加尔）身上的蜱虫进行全身采集。共鉴定出四个蜱属和八个蜱种。它们分别是鳞斑钝眼蜱、小亚璃眼蜱、截形璃眼蜱、变异革蜱、卡米卡革蜱、埃氏革蜱、吉氏革蜱和穆氏革蜱。观察到鳞斑钝眼蜱和吉氏革蜱有显著（P≤0.05）的季节性活动模式，其活动高峰期出现在雨季。蜱虫平均数量最高（7.26±0.58）的记录出现在阿布纳马，而最低平均数量（3.61±0.31）出现在森纳尔。瓦蒂什型绵羊身上携带的蜱虫显著（P≤0.05）多于阿什加尔型。
