In November 1972, 93 out of 100 African buffalo from 3 areas in Ngamiland, Botswana, were found to be infested with ticks. The tick species present and the percentage of buffalo infested by each were: Hyalomma truncatum (63%), H. rufipes (54%), Rhipicephalus evertsi evertsi (68%), R. tricuspis (11%), R. simus (4%) and Boophilus decoloratus (1%). The mean number of ticks per animal was 8,6 (standard deviation +/-4,1), representing a mean of 6,5+/-3,4 male and 2,1+/-1,9 female ticks. The incidence of infestation with H. truncatum and the number of ticks of this species on infested animals were lowest in areas where plentiful surface water was responsible for an increase in humidity.
1972年11月，在博茨瓦纳恩加米兰地区3个区域的100头非洲水牛中，发现93头感染了蜱虫。存在的蜱虫种类以及每类蜱虫感染水牛的百分比分别为：截形璃眼蜱（63%）、红足璃眼蜱（54%）、氏扇头蜱（68%）、三尖瓣扇头蜱（11%）、牛扇头蜱（4%）和无色牛蜱（1%）。每头动物身上蜱虫的平均数量为8.6只（标准差±4.1），其中雄性蜱虫平均数量为6.5±3.4只，雌性蜱虫平均数量为2.1±1.9只。在地表水丰富导致湿度增加的区域，截形璃眼蜱的感染率以及感染动物身上该种类蜱虫的数量最低。
