Bioecology of ticks causing the most important pathology in France.
The principal tickborne diseases in France are carried by 4 species of tick. Argas reflexus lives in close proximity to pigeons. Ixodes ricinus is found in humid environments, particularly forests. Dermacentor reticulatus is found in a wide variety of habitats, such as degraded urban and suburban environments, and in rural environments such as prairies and heathland. Rhipicephalus sanguineus is totally adapted to life on canine hosts on which all 3 developmental stages take place. It is found mostly in the south Mediterranean and south-west. The biology of the host, host choice, geographical distribution, ecology and taxonomy of the species are discussed. Their role as disease vectors is described.
