Abstract:
The purpose of this study was to determine the species spectrum of ticks infesting goats owned by resource-limited farmers in the state-owned communal land areas of Zimbabwe. Ticks were collected from goats at a single locality within each of 5 communal land areas, and a total of 14 ixodid tick species was recovered. The most numerous tick was Rhipicephalus evertsi evertsi, which was present in all areas at each sampling, and a Rhipicephalus sp. (near R. punctatus), which was most abundant on goats in the central regions of Zimbabwe during the March rainy season. Amblyomma hebraeum was present on goats in all areas sampled. In the eastern central region its distribution overlapped that of Amblyomma variegatum, while in the northwest it overlapped those of both Amblyomma marmoreum and A. variegatum. Hyalomma truncatum was present at all localities, whereas only a single Hyalomma rufipes was recovered. Rhipicephalus appendiculatus was collected from goats in the moist, slightly cooler regions, while the few Rhipicephalus zambeziensis recovered were present in the hotter, drier regions. Species recorded in lower numbers were Rhipicephalus (Boophilus) decoloratus, Rhipicephalus lunulatus, Rhipicephalus simus, Rhipicephalus tricuspis and Rhipicephalus turanicus. Attachment in the inter-digital space of adult A. hebreaum and H. truncatum was sometimes associated with lameness.
