From both human and veterinary viewpoints, ticks are very important vectors. Methods and results: This cross-sectional research was conducted to study the prevalence, tick dis- tribution, and related risk factors in the Borana pastoral region of the Yabello district, Oromia re- gional state, Ethiopia. A total of 445 cattle were examined for the presence of tick infestation collected from different body parts of the cattle and 89.89% (400/445) of indigenous cattle harbor a total of 7,778 adult ticks belonging to four different genera of ticks namely Rhipicephalus (78.31%), Amblyomma (13.46%), Boophilus (7.01%), and Hyalomma (1.22%). Besides, Rhipicephalus pulchellus (73.17%) and Amblyomma varigatum (7.57%) were among the most prevalent tick species identied whereas Hyalomma dromedari (0.08%) was found to be the least one. In this study, high proportions of ticks were collected from the head and ear (34.57%) followed by anus and vulva (29.47%), scrotum/udder (19.18%), dewlap and neck (8.77%), brisket (7.16%) and belly and back (0.85%). Moreover, a high proportion of Amblyomma species were collected from scrotum/udder (47.76%) and brisket (38.01%); Rhipicephalus species from head and ear (41.14%), anus and vulva (33.64%); Hyalomma species from scrotum/udder (41.05%), anus and vulva (28.42%) and dewlap and neck (20%) whereas most Boophilus species were collected from anus and vulva region (32.48%) and head and ear (31.19%). A statistically signicant difference (P < 0.05) was observed among potential risk factors like age group being higher in adult animals and different kebeles such as Dharito kebele and Dida Tuyoura ranch. Conclusion: The result of this survey indicates that economically important ticks are widespread throughout the study areas and their presence in abundance is alerting. To minimize losses attrib- uted to ticks and tick-borne disease cost-effective control strategy should be designed. © 2021 The Authors.
