Aedes AegiziThe mosquito that has attracted the most attention is the Aedes aegizi mosquito. It belongs to the Culcidae family, composed of approximately 2,500 species (Encyclopedia Britanica 1999), together with other mosquito genera such as Anopheles, Culex, Orthopodomyia and Toxorynchites, to name just a few (Womack 1993, EB 1999). This mosquito is best known for transmitting yellow fever and human dengue throughout the tropical and subtropical areas of the Americas (Womack, M 1993). This mosquito, along with others, is considered a pest and nuisance in modern society due to their attraction to moisture. , lactic acid, carbon dioxide, body heat and movement (EB 1999) but we cannot confuse the Aedes a Egypti with any other mosquito because it has a very distinct appearance as well as a specific habitat. It has many related species and its geographical distribution is extremely wide and varied. Aedes a Egypti, as regards both sexes, are generally similar in coloration (Womack 1993). The adult female can be seen by her small dark figure colored by white spots and her banded legs. Its proboscis or snout is mostly black compared to white palp tips (Russel 1996). The dorsal pattern of the white scales on the scute has the shape of a 'lyre' with two central stripes at the base which contrast with the dark scales present on the insect (Womack 1993, Russell 1996). Its wings are dark scaled, and its femur and hind legs have light scales about three-quarters, and dark scales about two-thirds (Russel 1996). The first to fourth segments of the hind tarsi are characterized by white rings and the fifth segment is all white. Adults can be found abundantly in cities near human habitations, living in trees, herbaceous plants, dark closets, cabinets, or even old car tires (Womack 1993, Giuliano 1998). The species feeds mainly during the day, increasing the feeding rate two hours after sunrise and several hours before sunset (Womack1993, Geographical Magazine 1998), while it is not uncommon for females to feed under artificial light at night. The aforementioned feeding habits of Aedes a Egypti contribute to the lifespan of the species which depends on nutrition, temperature and humidity (Womack1993) as well as its ability to avoid predators such as reptiles or sometimes even other types of mosquitoes (EB 1999 ). The male mosquito can only live for a short time, from a few days to a couple of weeks, while the female can live up to a month, which allows her to reproduce longer (Womack 1993).
