Cattle are the most common and widely distributed large ruminant livestock species in Taraman animal farm, Sohag governorate. They are liable to be infected with many ectoparasites (e.g., ticks, mites, biting flied, fleas and lice). The cattle tick, Rhipicephalus annulatus is only the hard tick species found most often on cows in the studied farm. Heavy tick burdens on animals can decrease animal production (milk, meat and growth). In addition to hides damage. Moreover, the blood-sucking ectoparasites may act as vector for some diseases. The cattle tick, Rhipicephalus annulatus was found abundantly on cattle at this farm, but its occurrence is more frequent on cows. The densities of R. annulatus on cows during 2018 and 2019 years were studied, The numbers of  it were increased gradually started from the beginning of winter until reached their maximum numbers in spring season, especially in April, followed by the summer season (July), winter season was the last one in the individuals of R. annulatus on cow bodies.
