Les Ixodidae (Acariens, Ixodoidea) parasites de carnivores sauvages dans les alpes francaises et leur avant-pays. - From their own collections of tick (Ixodidae) parasites of more than 600 wild Carnivora in the French Alps and their surroundings, the authors emphasize the high prevalence of the two burrow-inhabiting species which are host specific to Carnivora, Pholeoixodes hexagonus and Pholeoixodes canisuga, widely distributed in the area and a lower incidence of an other specific tick, Pholeoixodes rugicollis. Other species are recorded. In Northern French Alps, all are exophilous (Ixodes ricinus and Dermacentor reticulatus); in Southern French Alps, one of them is exophilous (Rhipicephalus turanicus), but others are burrow-inhabiting (Rhipicephalus pusillus and Ixodes ventalloi, rabbits being the preferred hosts), or endophilous ticks (Rhipicephalus sanguineus). The Carnivora ixodid fauna is almost the same in Northern Alps and in Eastern France, but it is quite different in the Southern French Alps (mediterranean species being involved). Qualitative and quantitative variations of parasitism related to various carnivorous species have been studied.
