Rhipicephalus (Boophilus) microplus, although newly introduced in Côte d’Ivoire, is well known to livestock producers in other countries. This tick has a strong invasive power because several parameters such as its strong resistance to common acaricides. In our study, we assessed the level of diversity of R. (B.) microplus populations. The ticks were collected in November 2014 from cattle on ten (10) farms located north of Côte d’Ivoire. These farms are located on the transhumance corridor located between Côte d'Ivoire and Burkina Faso. After the identification of the ticks, seven (7) species were obtained. The species R. (B.) microplus was numerically in the majority with 82.78% followed by Amblyomma variegatum with 14.86%. The other species were obtained in very small proportions. Analysis of the qualitative and quantitative parameters therefore allowed us to highlight a variation of form of R. (B.) microplus which is a species capable of transmitting pathogens.
