The results of tick surveys carried out in the Eastern province of Zambia between December 1982 and February 1996 were principally in agreement with the findings of earlier surveys conducted during the period 1965-72. Boophilus decoloratus has almost been replaced by Boophilus microplus. Hyalomma truncatum was found in small numbers throughout the province and Hyalomma marginatum rufipes was only rarely encountered in collections made from cattle. Rhipicephalus evertsi evertsi was largely confined to the southern part of the plateau and the valleys of the Zambezi tributaries. The main difference between the present survey and the previous one concerns the status of Rhipicephalus appendiculatus. This species is currently expanding its range in a westward direction, whereas it was virtually absent from the southern part of the province during the period 1965-72. The majority of specimens collected are morphologically intermediate between R. appendiculatus and the closely allied Rhipicephalus zambeziensis. The available evidence indicates that R. zambeziensis (sensu stricto) is absent from the province. The phenology of R. appendiculatus is aberrant in the province: at lower altitudes a second generation of adult ticks is recorded on the hosts at the start of the dry season.
1982年12月至1996年2月在赞比亚东部省份开展的蜱虫调查结果,与1965 - 1972年期间早期调查的结果基本一致。微小牛蜱几乎已取代了消色牛蜱。截形璃眼蜱在全省范围内数量较少,而边缘璃眼蜱红足亚种仅在牛身上采集到的样本中很少遇到。埃氏扇头蜱主要局限于高原南部和赞比西支流的山谷。本次调查与上次调查的主要差异在于 appendiculatus 扇头蜱的分布状况。该物种目前正在向西扩展其分布范围,而在1965 - 1972年期间该省南部几乎没有这种蜱。采集到的大多数样本在形态上介于 appendiculatus 扇头蜱和近缘的赞比亚扇头蜱之间。现有证据表明该省不存在严格意义上的赞比亚扇头蜱。appendiculatus 扇头蜱在该省的物候异常:在较低海拔地区,旱季开始时在宿主身上记录到第二代成年蜱。
