  1. The mosquitos

  2. What are mosquitos? • TheCulicidae, commonlycalledmosquitos are classified in the order Diptera and suborder Nematocera, they are characterized by long and thin antennas multiple articles. • Sizes: - Larval stage (3-10mm) - Adult stage (3-40mm)

  3. Diptera are two types of antennas: • -The Nematocera (mosquitoes) have got long antennae at least six articles. • - The Brachycera (flies) have short antennae of three articles.

  4. These are anticoagulants and vasodilators that the female let under the skin that are responsible of itching.

  5. Why are some people bitten more than others? • First of all mosquito mark the target with its smell. It is first able to feel the presence of carbon dioxide (emitted by breathing) more than thirty feet away. More it approaches, the more it will detect humans odors composed of fatty acids (sebum, butyric acid), lactic acid or other hints ammonia emitted from the skin, such as breath or urine. When it is near to the human skin, it uses thermo-receptors. These sensors infrared heat will allow it to find the venule warmer, within which it will draw the blood necessary for its eggs. The visual system, particularly sensitive to movements, is actually very inefficient.

  6. Favoritebody smell • The mosquitos are attracted by body smell organisms. The latter are related to pheromones that we issue, and some of which are more attractive than others. This may be related to food, the amount of sweat, the use of a perfume but also the bacterial composition of our skin. • Are also adding that pregnant women are generally bitten more because of hormones secreted abundantly.

  7. Also we can say that people spared by mosquitoswould diffuse more repellent compounds. Conversely, people assailed by mosquitosnaturally emit less than other repellents.

  8. Characteristics of Diptera • Has a pair of membranous wings and the second pair is posterior transformed into two short stumps called halteres. • More about 6000 species identified. Back

  9. Characteristics of Nematocera • Dipterous insect forms hail antennas and generally in wire form. Back

  10. Characteristics of Culicidae • The culicidae have a slim body, wings provided with scales, long thin legs. In most species, females differ from males with their feathery antennae and mouth parts long trumpet-shaped rigid piercing-sucking. Back

  11. Anticoagulants: A substance that makes the blood more fluid to collect. • Vasodilators: Substance to dilate the vein in order to obtain a greater flow of blood. Back
