Ixodid ticks were collected from domestic animals, mainly cattle, in 11 administrative zones covering 84 districts in central Ethiopia over a period of 2 years (July 1996 to June 1998). Nineteen tick species were identified. Four of these belonged to the genus Amblyomma, one to Boophilus, two to Haemaphysalis, three to Hyalomma and nine to Rhipicephalus. Amblyomma variegatum and Rhipicephalus evertsi evertsi were present in all 11 administrative zones and, with the exception of Afar, Boophilus decoloratus was present in nearly every district in which collections were made. These three species constituted more than 50% of all ticks collected. Amblyomma cohaerens and Rhipicephalus bergeoni were common in the west of the survey region and Rhipicephalus pulchellus in the east. Except for B. decoloratus, of which more females than males were collected, the numbers of male ticks recovered were equal to or exceeded those of females. Mortality in crossbred dairy cattle caused by heartwater (Cowdria ruminantium infection) was reported during the survey period. An integrated approach to tick control is suggested.
在两年时间（1996年7月至1998年6月）内，从埃塞俄比亚中部84个区的11个行政区的家畜（主要是牛）身上采集了硬蜱。共鉴定出19种蜱。其中4种属于钝缘蜱属，1种属于牛蜱属，2种属于血蜱属，3种属于璃眼蜱属，9种属于扇头蜱属。变异钝缘蜱和埃氏扇头蜱在所有11个行政区均有发现，除阿法尔州外，在几乎每个采集样本的地区均发现了无色牛蜱。这三种蜱占所有采集到的蜱的50%以上。联合钝缘蜱和伯氏扇头蜱在调查区域西部较为常见，美丽扇头蜱在东部较为常见。除无色牛蜱采集到的雌性多于雄性外，回收的雄蜱数量等于或超过雌蜱。在调查期间报告了由心水病（反刍兽考德里氏体感染）导致的杂交奶牛死亡情况。建议采取综合蜱虫控制方法。
