Possibilities of persistence in new biotopes of ticks imported by birds.

Survival and development of 6 tick species (Hyalomma anatolicum, Rhipicephalus sanguineus, Haemaphysalis punctata, Dermacentor marginatus, D. reticulatus and Ixodes ricinus) were studied in 3 groups differing in the range of distribution with respect to the place of importation, as a model for the knowledge of their possible inclusion in the new local biocenosis during transportation by natural hosts.
