MOSQUITO AEDES AEGYPTI

The female mosquito Aedes aegypti is the responsible of transmitting the diseases of dengue, chikungunya, zika, yellow fever and mayaro. The mosquito does this by means of a structure in its head called proboscis, this consists of two tubs like needles held together by hooks with the ones they bite, through this tubs, the mosquito sucks the blood and injects saliva, this saliva is the one that transmits the viruses, such as dengue. Only female mosquitoes bite, using the blood for feeding, but mainly extracting the amino acid for egg production.

The mosquito transmitter of dengue produces little noise in its flight, and commonly bites in lower parts of the body like ankles, elbows and the back. They are very persistent insects so trying to scare them with the hands usually doesn’t work. These mosquitoes are most active through the first hours of the day and at sunset, but they can also bite during the night in the presence of artificial light. Their favorite spots to lay their eggs are dark places like, old tires, planters, and places where rain water stagnates.

Dengue fever is an acute viral disease, produced by the dengue virus, it is transmitted by the Aedes aegepty mosquito or the Aedes albopictus they are developed where water stragnates and in objects that are not usable. Dengue infections are caused by 4 serotypes called DEN-1, DEN-2, DEN-3, DEN-4, these viruses are related to the Flavivirus from the flaviviridae family. The dengue virus has increased during the past decades. More than 2500 millions of people and 40 % of the world population are in risk of getting the dengue disease. The OMS calculates that between 50 and 100 millions of infections are caused by the dengue virus.
