Résumé
Ticks are vectors of various infectious pathogens causing animal and human diseases of considerable economic importance. The control of tick-borne diseases has become increasingly problematic the last decades due to acaricide resistance present in many regions of the world. The general aim of this study was to investigate the occurrence of ticks and tick-borne pathogens in the cattle population of the Rabat-Sale-Kenitra region of Morocco using molecular based methods and to evaluate the efficacy of diazinon and amitraz in Hyalomma marginatum ticks collected from different agro-climatic locations in the study region. Adult ixodid ticks were collected from cattle and morphological identification revealed the presence of eight different tick species representing two genera, Hyalomma (84.1%) and Rhipicephalus (15.9%). The collected ticks consisted of Hyalomma marginatum (38.9%), Hyalomma anatolicum excavatum (33.1%), Rhipicephalus sanguineus sensu lato (9.9%), Rhipicephalus bursa (5.4%), Hyalomma detritum (4.3%), Hyalomma lusitanicum (3.7%), Hyalomma dromedarii (3.7%) and Hyalomma impeltatum (1.1%).
