Aedes Aegypti

The mosquito that has attracted the most attention is the mosquito Aedes aegypti. It belongs to the family Culcidae, consisting of about 2,500 species (Encyclopedia Britanica 1999), along with other genera of mosquitoes such as Anopheles, Culex, Orthopodomyia, and the Toxorynchites, to name a few (Womack 1993, E.B. 1999).

Adults can be found in abundance in towns and cities near human dwelling places., living in trees, herbaceous plants, dim closets, cabinets or even old automobile tires (Womack 1993, Juliano 1998). The species feeds mostly during the day increasing its feeding rate two hours...
