Content : Ticks are the most important vectors of pathogens affecting both domestic and wild animals worldwide. The geographical distribution of several tick species is believed to have expanded due to both the intensification of human and animal activity, and socio-economic and environmental changes. The recent colonization by Rhipicephalus (Boophilus) microplus of East-African regions provides an excellent illustration of this risk. Consequently, the emergence or re-emergence of tick-borne-diseases (TBD) is a growing threat for both humans and animals. Indeed, changes in climate and human practices are spurring extension of the geographical distribution of exotic TBD, as illustrated by recent incursions of the virus responsible for Crimean Congo hemorrhagic fever in Europe. It is well known that both abiotic (temperature, rainfall and relative humidity) and biotic (animal abundance and herbaceous strata) factors influence tick densities and activity locally. However, to date, detailed studies on the impact of climate change on tick population densities are still lacking.
