Mosquito that spreads dengue fever Chikungunya and yellow fever

The yellow fever mosquito, Aedes aegypti 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 on legs and a marking of the form of a lyre on the thorax. 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. Research has shown that certain chemicals emanating from bacteria in water
containers stimulate the female mosquitoes to lay their eggs. They are particularly motivated
to lay eggs in water containers that have just the right amounts of specific fatty acids
associated with bacteria involved in the degradation of leaves and other organic matter in
water. The chemicals associated with the microbial stew are far more stimulating to
discerning female mosquitoes than plain water, for example, or filtered water in which the
bacteria once lived
