Summary : A study was carried out in the north of Benin in September and October 2003 and 2004 with the aim of identifying the different species of ticks present on ruminants as well as the prevalence of hemoparasites transmitted to cattle. During these wintering periods, smears were carried out from the peripheral blood taken on 200 bovines of the 2 sexes and the different age groups in 4 localities of the Departments of north-Benin. Ticks were also collected on 30 animals in each breeding. After Giemsa staining, 4 hemoparasites were identified from the blood smear : Babesia bigemina (57%), Theileria mutans (46.5%), Anapalasma marginale (39.5%) and Anaplasma centrale (28.5%). Polyparasitism was frequent: Babesia-Anaplasma (39.62%), Babesia- Theileria (27.36%), Babesia-Theileria-Anaplasma (20.75%), Anaplasma- Theileria (12.26%) associations were observed. Ten species of ticks were identified: Amblyomma variegatum (23.5%), Boophilus annulatus (7.72%), Boophilus geigyi (32.68%), Hyalomma impressum (3.37%), Hyalomma marginatum (6.39%), Hyalomma nitidium (3.05%), Hyalomma truncatum (5.97%), Rhipicephalus mushamae (5.71%), Rhipicephalus senegalensis (11.22%), and Rhipicephalus sulcatus (0.84%). The dominant species in the study period were : Boophilus geigyi (32.68%), vector of Babesia bigemina; Amblyomma variegatum (23.5%), vector of Theileria mutans, and Rhipicephalus senegalensis (11.22%), vector of Anaplasma sp. The analysis of the hemoparasites results showed that overall the adult bovines were more infested than the young ones (p <0.05) whereas sex did not have any influence on the infestation rate.
