The ARS warns of the presence of the tiger mosquito. The very small insect can be content with a small amount of water to grow discreetly, and it can be a vector of serious diseases.
The Bourgogne-Franche-Comté region has not escaped the progress ofAedes albopictus, known as tiger mosquito. Established for many years in overseas territories, particularly in the Indian Ocean, it has been developing since 2004 in Metropolitan France. It is today located in five departments of the region : in Saône-et-Loire, since 2014; in Côte-d’Or and Nièvre since 2018; in Doubs and Jura since 2020. Indeed, its presence has been spotted at Arc-et-Senans and Dole.
An insect vector of serious diseases
The danger of the tiger mosquito lies above all in its ability to be vector of serious diseases, such as chikungunya, dengue or zika virus. In metropolitan France, it is active from May 1 to November 30. The health authorities are therefore particularly vigilant to prevent its progression. The insect is very annoying. Unlike other mosquitoes, it also stings during the day and its bite is painful.
The ARS (via a mosquito control operator) implements a surveillance throughout the region by a network of nesting traps, mainly in the most populated urban units, but this surveillance implies the vigilance of the population.
Spot and report the tiger mosquito
The tiger mosquito has several peculiarities: it is very small (less than 1 cm wingspan), it is black with white spots on the body and legs, it has a white line on the thorax and a biting device.
If you spot one, you can report it on the ANSES portal.
And to avoid its installation, it is advisable to monitor small reservoirs of standing water :
- Empty (once a week) cups and saucers under flower pots, animal bowls, folded tarpaulins, buckets, parasol bases, etc.
- Cover the water collectors
- Store (out of the rain) toys, wheelbarrows, buckets, watering cans
- Maintain gutters, ditches and channels
- Throw away waste and used tires
- Create a balance in the ornamental ponds: the fish eat the mosquito larvae.
