Abstract

Data from surveys in 1951, 1972, 1973 and 1978–79 showed that tick numbers are generally low on the miniature breed of cattle in the Yemen Arab Republic and tick-borne diseases have not been recognised as a serious problem. This breed should be investigated for properties of resistance to tick bite. Each tick species commonly infesting livestock has been recorded as transmitting viruses (and some also rickettsiae) causing human illness in Africa and/or Eurasia. Between 1300 and 2000 m in altitude, Amblyomma variegatum (F.) is more abundant on camels than on cattle and Boophilus annulatus (Say) infests cattle. Below 1500 m, B. kohlsi Hoogst. & Kaiser is more abundant on goats than on sheep. Haemaphysails sulcata C. & F. infests sheep in certain highland areas. Hyalomma dromedarii Koch is the most prevalent and abundant tick of livestock. H. anatolicum excavatum Koch is next in abundance on camels. The numbers of H. anatolicum anatolicum Koch vary greatly in collections from different years. Few examples of H. erythraeum Tonelli-Rondelli were taken. H. impeltatum Schultze & Schlottke and H. marginatum rufipes Koch are widely distributed; the former is most abundant in coastal lowlands, the latter in humid habitats. H. arabica Pegram, Hoogst. & Wassef is recorded from goats, and also sheep, in southern hills. Immature examples of Hyalomma spp. are especially abundant on camels and hares. Rhipicephalus evertsi evertsi Neum. is common in the highlands, as is R. simus Koch below 2000 m. Species of the R. sanguineus (Latr.) group occur on some livestock.
