But after the trifle, the "moustiquette" keeps its spouse's semen in its spermatheque, a pocket situated under the abdomen. But to bring its eggs to maturation, the woman needs a supplementary contribution of proteins. For that to make, it leaves in quest of one meal from blood! According to its species, the moustiquette is going to move toward the horses the dogs. or the summer vacationers. Among the score of thousands of bugs that populate our regions, close to 300 species of mosquitos prick the man. Under our latitudes, are very little capable to transmit some illnesses. Guided by the detection of movements and colors, the winged female is also sensitive to several types of odors. It is on these criterias that she is going to choose prey. Once calm, it opens out its syringe capable to punch skin until a blood capillary. Before the aspiration, a little anticoagulant saliva is injected (it is responsible for the itches and buttons). The feast can begin! But how some people are they systematically victims of these stings? Portrait robot of the ideal victimVery numerous research tempted to identify the criterias of a particularly appetizing skin for the mosquitos. But the very numerous chemical compounds and odors emitted by skin return the difficult enterprise. One estimates that our own touchiness to be pricked is of genetic origin for close to 85%. But some types of odors are detected mainly until a distance of 50 meters. - People having strong concentrations of steroids or cholesterol to the surface of their skin are pricked more often. It doesn't necessarily have a tie with your global cholesterol rate but rather to your capacity to produce this compound.
- The mosquitos also mark the excessive quantities of some acids as the uric acid. A sweat rich in fatty acid as the acidic butyrique to the staleness ammoniaques or the lactic acid is also appreciated.
- The carbon dioxide is also attractive. The adults (and particularly the pregnant women) produce to some more that the children.
In summary to pass unobserved to the eyes and to the nose of the mosquitos, is better to remain lying on a lounger that to play soccer with your friends! Your movements will attract the attention of the starved piqueurs, all as your excessive exhalation of carbon dioxide or the production of acid contained in your sweat. Not to let you devour more!To save your skin of the ravenous appetite of these vampires, some advice of common sense is to respect: - Don't hesitate to limit the discovered zones while wearing the ample and long clothes covering the arms and the legs until the peg;
- Finally, even though the temperature lends avoid himself of it the muslins and other veils that the bugs transfix without pain;
- Don't forget to protect the feet and ankles;
- Impregnate the clothes with a special insecticide product. The repulsive absorbed in the fibers of cloths evaporate very slowly, conferring a longer-term protection thus. It offers some advantages in terms of persistence, cost and security of employment;
- Apply the repulsive on skin, they contain an active principle that moves away the bugs without killing them however. Precautions of employment are to respect at the pregnant woman and the child, and he agrees to take advice by a physician or a pharmacist.
So each summer, the anti-mosquitos products invade the rays of the pharmacies and supermarkets. But all are not equivalent. At the time of the epidemic of chikungunya, the institute of Vigil Sanitaire (InVS) had made the point on the most efficient products and the particular situations (notably the contra-indications for the pregnant women or the very young children). Finally, don't light light inside the house if the windows are open and avoid to keep close to your place of vacations of the stagnant water zones. In case of sting, an anti-inflammatory soothing cream will calm the irritation, will attenuate the itch and will avoid to scrape themselves all night long. 2009-07-26
