Are mosquitoes also stunned by high heat?
We asked the question to Rémi Foussadier, Director General of the EID (Interdepartmental Agreement for Mosquito Control) in Rhône-Alpes
With this heat wave hitting the department these days, are the mosquitoes stunned, like us, by these high temperatures? “Yes and no, observes Rémi Foussadier, general manager of the EID (Interdepartmental agreement for mosquito control) in Rhône-Alpes. Hot weather tends to have an impact on adult mosquitoes. At 20 degrees, females have a lifespan of six weeks, at 35 degrees, this duration is between three and four weeks. It is currently very hot but, from time to time, precipitation falls, thunderstorms break out which favor the development of larvae and a new production of adults.
To have a limitation of the species, it would take more than a month of drought without precipitation for the population of tiger mosquitoes to be affected. It is also prevention that makes it possible to protect once morest it,” recalls Rémi Foussadier. Prevention that involves good practices, storing and emptying containers where water can accumulate, checking the proper flow of water following rain, covering water tanks, preventing stagnation of water in swimming pools outside of use.
Present since 2012, in Auvergne-Rhône-Alpes, the tiger mosquito is starting to do well in 10 of the 12 departments of the region, including the Loire.
