As in other departments of the south of France, the level 1 of the departmental control plan, developed under the authority of the Prefect, is now enabled in the Aude also.

What is the tiger mosquito?

See image Grandle Aedes albopictus mosquito is a mosquito of tropical origin, also called "tiger mosquito" because of the stripes that run through his slender body.

It was detected during the summer of 2012 in the town of Narbonne and the motorway service area of ​​Vinassan by the Interdepartmental Agreement for mosquito control of the Mediterranean coast (EID Méditerranée). Its presence is confirmed: despite delaying treatment, eggs were observed repeatedly over several traps nests deposited by the SIA, as well as larvae and adults around the traps.

In 2013, there are three towns settled in the Aude: Narbonne, Carcassonne and Vinassan. The eradication of this mosquito is not possible.

Is the tiger mosquito disease carrier?

No, the mosquito is not itself carrying the virus of dengue or chikungunya. It can transmit if it has bitten, previously an already infected person.

>There is no possible transmission of the virus between humans. Since its appearance in France, there were only four cases of dengue or chikungunya in the Var and Alpes-Maritimes in 2010.

How can we fight against the tiger mosquito?

The tiger mosquito is an urban mosquito. A massive mosquito control campaign therefore serve no purpose. The fight is personal.

The goal is to eliminate its living spaces, its spawning and where its larvae develop. To eliminate mosquito larvae:

No mosquitoes

  • eliminate places where water can stagnate: small litter, bulky, old tires, green waste
  • change the water plants and flowers once a week. If possible remove the saucers of flowerpots or replace
  • water vases with wet sand
  • check the proper flow of rainwater and wastewater and regularly clean gutters, manholes, gutters and drainage
  • cover water tanks (water containers, tanks, ponds) with a net veil or a simple cloth
  • cover pools out of use, drain the water tarps or treat the water (bleach, chlorine roller)
  • To reduce adult mosquito resting places:

  • débroussaillez and trim the grass and hedges,
  • prune trees,
  • pick up fallen fruit and plant debris,
  • Reduce moisture sources (limit watering)
  • maintain your garden.
  • What is the role of the authorities?

    The General Council of the Aude has implemented a implantation monitor mosquito and struggle against its proliferation (entomological monitoring). It will decide the need for nest destruction operations and larvae and inform beforehand the people of the sectors concerned. These operations will be conducted by the EID Méditerranée. EID Méditerranée maintains and reports of nests traps to know the evolution and the degree of implementation of the mosquito. It provides health monitoring and advisory role to the public on the identification of the mosquito. She only at the request of the department; its mission is not to answer all the individual requests.

    The Regional Health Agency in charge of epidemiological surveillance (human case study). Once the mosquito is said implanted in a department, ARS provides information and sensitization of health professionals, so they know to recognize the disease and treat those who have it.
