Aedes aegypti is the mosquito that can be vector viruses that can cause diseases such as yellow fever, Chikungunya and dengue virus. This type has a very wide distribution, although originating from Africa but now can be found almost throughout the tropics and sub-tropical in the world. As the primary vector of dengue virus, A. aegypti and Aedes albopictus together create a dangerous disease that can develop in the woods, rural to urban areas.

Aedes aegypti mosquito has a relatively small size with a brownish-black body. Body and legs covered in patterned scales that white lines. At the back of his body were two vertical curved line on the left and right also patterned silvery white lines become characteristic of this species. Like other species, male mosquitoes are generally smaller than females and the presence of thick hairs on the antennae. Both these features can be observed with the naked eye.

This mosquito is active in the morning and afternoon, Aedes aegypti is also active in the daytime overcast, shaded places or in conditions that resemble it. Because only female mosquitoes which suck the blood of disease transmission was carried out only by female mosquitoes. Males do not need blood, and obtain energy from the nectar of flowers or plants. Females suck blood to obtain the protein necessary to reproduce.

Virus infection in Aedes aegypti may lead to behavioral changes that lead to increased vector competence, the ability of mosquitoes spread the virus. Viral infection can lead to decreased ability to suck blood, Aedes aegypti will move from one person to another person not being able to suck blood when stabbed probocis. As a result, the risk of dengue fever, yellow fever or Chikungunya becomes larger.

Mosquitoes A. aegypti, as well as other culicines, put the eggs on the surface of clean water. Eggs elliptical black and split apart. Then in 1 to 2 days the eggs become larvae. There are four stages in the development of larvae so-called instar. Required 5-day growth of instar 1 to instar 4. After reaching the 4th instar, the larvae turn into the pupa where the larvae enter the dormant period. Pupa period is 2 days before becoming adult mosquitoes. When environmental conditions support the development from egg to adult mosquito takes 7 to 8 days, but if not it will take longer.

Larvae in dire need of sufficient water for development, but unique Aedes aegypti eggs can survive up to 1 month in the dry state. When under water, dried eggs can be hatched into larvae. Conditions when developing larvae can affect the condition of the resulting adult mosquitoes. For example, the population of larvae that exceed the availability of food will produce adult mosquitoes tend to be more greedy in the blood sucking. Conversely, an environment that is rich in nutrients to produce mosquitoes that tend not very aggressive.
