About Aedes Aegypti
Aedes aegypti is the scientific name of a particular species of mosquito. Its common name is the yellow fever mosquito, because it is the most well-known vector of transmission for this disease. Aedes aegypti mosquitoes are of particular importance because they are common vectors for several serious diseases throughout the world.
Significance
The Aedes aegypti mosquito is the most common vector for three serious diseases that affect humans: yellow fever, dengue fever and the West Nile virus. They have also been implicated in the spread of the Ross River virus and Murray Valley encephalitis in humans, and heartworms in dogs and cats. Most species of mosquitoes in the United States do not spread disease, which makes the Aedes aegypti mosquito quite unusual.
Geography
The Aedes aegypti mosquito is found primarily in tropical and subtropical climates; it requires a very mild winter to survive. However, the mosquito is sometimes found in cooler climates during the summer months. Areas of the world infested with this species include southern Asia, the Pacific islands, northeastern Australia, the southern half of Africa, the northern half of South America and coastal regions of Mexico. Aedes aegypti is also found in the southern United States, particularly in Florida and the Rio Grande Valley of Texas.
Identification
The Aedes aegypti mosquito is smaller and darker than most mosquitoes; it is most readily identified by its clear white markings, particularly on the legs. It is seen most frequently in the summer months when it's actively breeding. Larvae of Aedes aegypti mosquitoes are not unlike other mosquito larvae; they are small and white with tan to brown heads. Larvae are seen in pools of standing water, where they wiggle about much like minuscule tadpoles.
Effects
The bite of the Aedes aegypti mosquito initially leaves a small white welt, which grows larger over several hours. This welt may be accompanied by a circular area of reddened skin. It itches intensely, like all mosquito bites, and may produce a flattened area of swelling. Unusual symptoms following the bite of this mosquito should be reported to a physician, especially if a high fever or severe headache occurs. These symptoms could indicate an infection transmitted by the mosquito.
Prevention/Solution
Aedes aegypti mosquitoes lay their eggs in standing water; the most effective method of control is to eliminate their breeding grounds. Birdbaths, wading pools and clogged gutters are common breeding grounds for this mosquito. Mosquitoes are most active at dusk and dawn, and bites occur most frequently at these times. Using an insect repellent containing DEET or permethrin will decrease the chance of being bitten.
