Tick infestation is an economically important condition in cattle. In addition to increasing susceptibility to other diseases, skin damages inflicted by ticks downgrade the quality of skin and hide and the production of milk and wool. Control of these parasites remains a challenge due to the presence of resistance to commercial acaricides. A cross-sectional study using a questionnaire survey followed by an in-vitro acaricidal efficacy test was conducted from 2014 to 2017 to check the existence of resistant tick species to chemical acaricide. Most cases of tick infestation (94.6%) were treated by owners following veterinary professionals’ advice (69.4%). Amblyomma variegatum (A. variegatum), Boophilus decoloratus (B. decoloratus) and Rhipicephalus evertsi evertsi (R. evertsi evertsi) test and reference engorged female ticks were subjected to a modified larval packet test (LPT). Except for the mortality rate (3.33%) in the control group, both test and reference treatment groups exhibited a higher mortality rate (90% to 100%) at all tested concentration levels. A significant variance (P=0.0001) proofed by statistics was detected among test tick species. The LC50 of Diazinol against A. variegatum, B. decoloratus, R. evertsi evertsi and for their references was 0.03834, 0.0783, and 0.03834, respectively. A. variegatum and R. evertsi evertsi showed a resistance factor of 1.310, while B. decoloratus exhibited a factor of 2.676 indicating a level 1 resistance for Diazinol. Further investigation on the existence and seasonal dynamics of other tick species should be investigated. Future works should also look at the utilization of acaricides in a wider area of the district and their efficacy against the existing tick species. Furthermore, farmers’ awareness on the utilization of acaricides should be enhanced through training.
