Everything about Aedes Aegypti totally explained
Aedes aegypti, commonly known as the
yellow fever mosquito, is a
mosquito that can spread the
dengue fever,
Chikungunya and
yellow fever viruses, and other diseases as well. The mosquito can be recognized by white markings, although other mosquitos may have only slightly different patterns. The mosquito is most frequently found in the
tropics; it has some presence in the
southeastern United States (such as the lower half of
Florida), but it seems to have been competitively displaced by the introduction of
Aedes albopictus.
Genomics
The
genome of this species of mosquito was sequenced by a consortium including scientists at the J Craig Venter Institute and the University of Notre Dame, and published in 2007. The effort in sequencing its
DNA was intended to provide new avenues for research into
insecticides and possible genetic modification to prevent the spread of disease. This was the second mosquito species to have its genome sequenced in full (the first was
Anopheles gambiae). The published data included the 1.38 billion
base pairs containing the insect's estimated 15,419
protein encoding genes. The sequence indicates that the species diverged from
Drosophila melanogaster (the common fruit fly) about 250 million years ago, and that
Anopheles gambiae and this species diverged about 150 million years ago.
Spread of disease and prevention
The
CDC traveler's page on preventing dengue fever suggests using
mosquito repellents that contain
DEET (N, N-diethylmetatoluamide). It also explains the following:
- Although it may feed at any time, the mosquito bites humans only between a few hours after dawn until an hour or so after sunset.
- The mosquito's preferred breeding areas are in areas of stagnant water, such as flower vases, uncovered barrels, buckets, and discarded tires, but the most dangerous areas are wet shower floors and toilet tanks, as they allow the mosquitos to breed right in the residence.
