Description

The Aedes aegypti mosquito is small, with a body length of about 4 to 7 mm. It is dark in color, with white markings on its legs and a marking in the form of a lyre on its thorax. The mosquito can be recognized by white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax.

Behavior

Aedes aegypti is a daytime feeder. Its peak biting periods are early in the morning and in the evening before dusk. The mosquito is known to bite humans more than any other species.

Disease Transmission

Aedes aegypti is a vector for transmitting several tropical fevers. Only the female bites for blood, which she needs to mature her eggs. Each batch of eggs requires a fresh blood meal. She is a carrier of several viruses including dengue fever, chikungunya, yellow fever, Zika virus, and other diseases.

Control

Control of Aedes aegypti is of paramount importance in reducing the incidence of diseases it transmits. This can be achieved through source reduction, pesticide spraying, use of mosquito nets and repellents, and community education.
