Tick collections at nine sites, at 3, 600, 4, 500 and 5, 500-6, 000 feet, showed Rhipicephalus appendiculatus and Amblyomma variegatum to be the most abundant species (73% and 21% of ticks collected). Other species found on cattle were R. evertsi evertsi, R. simus simus, R. tricuspis and, infrequently. Boophilus decoloratus. Male ticks exceeded females except in B. decoloratus. R. appendiculatus may be more common than A. variegatum. because of differences in mortality rate of the young stages, a more severe skin reaction towards A. variegatum, and a greater food requirement in this species. Climatic data are recorded for the collection sites. Seasonal variations in numbers of R. appendiculatus showed an increase in immature ticks in Jan.
