The fight once morest the tiger mosquito is an integral part of vector control (LAV). The mosquito Aedes albopictus (commonly called “tiger mosquito”) is a mosquito native to Asia. It is the vector of diseases such as dengue fever, chikungunya or zika. In mainland France, this mosquito has developed rapidly since 2004 and is now present in 67 departments.
More recently, another very common type of mosquito, the Culex pipienstransmitted another type of virus, the West Nile virus (or West Nile Virus)
These official tiger mosquito presence maps (Aedes albopictus) in mainland France are intended for the information of decision-makers and the general public. They are updated regularly.
Presence map of vector mosquitoes Aedes albopictus
At the end of 2021, 67 departments are colonized by the mosquito vector Aedes albopictus (out of the 96 metropolitan departments)
The tiger mosquito is essentially urban. Its anthropophilic character (which likes places inhabited by man) explains that once installed in a municipality or a department, it is practically impossible to get rid of it. The departments in which the tiger mosquito is established and active are divided into 2 categories, the weakly colonized departments if less than 40% of the communes of the department are colonized, the strongly colonized departments if at least 40% of the communes of the department are colonized.
Dissemination ofAedes albopictus (tiger mosquito) over time
The file below consists of a set of maps showing the departments colonized by Aedes albopictus for each year from 2004 to 2021.
Exposed population
The map below shows the % of population per department living in the municipalities where the tiger mosquito is present:
In each department, the implantation of the Aedes albopictus mosquito is not homogeneous, citizens contribute to the knowledge of the implantation of this mosquito vector by indicating its presence on the website At the end of 2021 the implantation of the tiger mosquito was noted and confirmed in 3,934 municipalities in mainland France.
