A cross sectional study was carried out to investigate the prevalence and species diversity of iIxodid ticks that parasitize dromedary camel since October 2016 to March 2017. A total of 384 dromedary camels from five peasant association in Yabello district were examined for tick infestation. Accordingly, 374 (97.4%) camels were found to habour one or more species of ticks. A total of 4417 ticks were collected from infested camels from different body regions. The average tick burden from different body regions of camels was 11.8 ticks per camel while a male to female ratio was found to be 1.9 to1. Four genera of ticks namely Rhipicephalus (85.6%) Ambylomma (3.65%), Hyalomma (5.57%) and Boophilus (1.34%) and eight species of ticks namely Rh. pulchellus, Rh . pravus, A. gemma, A. lepidium, A. variegatum, H,.m. rufipes, H. dromedary and B. decoloratus were identified at a prevalence of 90.6%, 28.4%, 27.1%, 2.9%, 4.7%, 18.5%, 27.9%, 10.4%, respectively.Considering attachment sites, Rh. pulchellus has preference for sternum, ana-vuval, head, udder/scrotum and inguinal, Rh. pravus for head, sternum and anal/vulvaA/v ; A . gemma for udder/scrotum and B. decoloratus in different body parts. H . rufipes preferred head, sternum and anal/vulva and H. dromedary preferred head, sternum, anal/vulva and udder/scrotum regions. In case of male to female ratio all tick species had higher number of males than females except B. decoloratus which had higher number of females than males.There was statistically significant difference in prevalence and level of tick infestation (p<0.05) between selected pastoral associations(PAs) groups of Yabello district and herd size. However prevalence of tick infestation with regard to sexes, age and body condition scores were found to be statistically insignificant (p>0.05). Tick infestation was found to be among serious health problem of dromedary camel in the study area with higher risk of exposure of these animals to tick-borne diseases. Therefore, this problem observed in the study area warrants immediate professional intervention through implementation of community based sustainable control strategies.
