Update on the situation with Public Labs.
Gardens invaded at aperitif time, and particularly unpleasant stings. The tiger mosquito is more present than ever in the Lot: in Cahors, Pradines, Figeac, Souillac… The departmental analysis laboratory, Public Labs, has been entrusted by the Regional Health Agency with monitoring the mosquito tiger.
Emmanuel Esposito, general manager of the structure, and Nelly Thomas, animal health technician and tiger mosquito referent, take stock of the situation. “The tiger mosquito appeared in the Lot in 2015. Today, it has been detected with a proven presence in 70 municipalities, i.e. 22% of the 313 municipalities, but this represents a population of 98,745 inhabitants out of a total of 173,922. This which does not mean that it cannot be present elsewhere. It is ultra invasive, like other species, but also potentially a vector-borne disease transmitter: dengue, Zika, Chikungunya… It is a mosquito that spreads via human activity… it adapts very well. The question is how do we take this issue into account with the themes of water recovery and urban planning? ” they explain before giving advice to fight once morest this mosquito which is now part of our daily lives: ” We can only limit its presence… There is a site https://signalement-moustique.anses.fr/signalement_albopictus/ which allows you to indicate your presence in a municipality that was not yet listed. We then contact people to explain the right gestures to them. We can also inform people regarding an already colonized municipality. Our advice is intended for individuals but also for communities. The tiger mosquito develops in stagnant water reserves: water collectors, manholes, cups in cemeteries, tarpaulins, flower pots with a water reserve… an empty can, an abandoned plastic bag is enough for it. … mosquitoes have an aquatic development phase (larvae and nymphs) of at least 7 days. Each mosquito, with a life expectancy of 3 weeks, lays up to 100 eggs per clutch. It lays flush with the water line… For water collectors, you can place a mosquito net or a very fine curtain at the water’s edge. It is necessary to empty the saucers of the flower pots or fill them with sand, to regularly remove or empty the small containers which can contain water in the gardens… For the bowls of animals, it is necessary to change the water often and to clean the container because they can lay eggs on it…” And to conclude: “To fight once morest the tiger mosquito, the right actions are essential. It is a collective problem because the tiger mosquito does not know the limits of property and can move within a radius of 150 m – 200 m. The message got through.
