In order to determine ticks’ prevalence and abundance on cattle and sheep in the Poro Region of Côte d'Ivoire, 809 ticks were collected from 120 cattle and 311 ticks from 120 sheep. Six species have been identified: Amblyomma variegatum, Rhipicephalus (Boophilus) microplus, Boophilus annulatus, Boophilus geigyi, Hyalomma truncatum and Rhipicephalus senegalensis. Cattle were more infested by these ticks excluding Rhipicephalus senegalensis, which had a higher prevalence in sheep (12.5% in sheep versus 4.17% in cattle). The species Boophilus geigyi was most abundant in cattle of Dikodougou department (42.96%), then in sheep of Sinématiali (60%) and M'Bengué (51.72%) departments. In addition, Rhipicephalus senegalensis was more abundant in sheep in Korhogo Department with a proportion of 51.39%. These results suggest that tick control needs to be strengthened to improve the productivity of domestic ruminants in the Poro Region of Côte d'Ivoire.
