It is the mosquito that transmits Dengue, Zika, Chikungunya, and Urban Yellow Fever. It originates from Africa, is smaller than common mosquitoes, has a black body with patterns forming a small cup-like design on the thorax, and white stripes on its head and legs. Its wings are translucent, and the noise it makes is almost inaudible to humans.
The male, like those of any species, feeds exclusively on fruit. The female, on the other hand, needs blood for the maturation of her eggs, which are laid in artificial containers, such as empty cans and bottles, tires, uncovered water tanks, or any other objects that can store rainwater. The mosquito can also seek natural breeding grounds, such as bromeliads, bamboo, and holes in trees.

ACTIVITY PROPOSAL
FAVORABLE ENVIRONMENT FOR MOSQUITO BREEDING
One of the major problems of dengue is that the Aedes Aegypti mosquito easily reproduces in any container with stored water.
Removing stagnant water is essential, so it is crucial to regularly check places that can accumulate water. Water containers should always be well covered and, if possible, cleaned frequently. Gutters and drains must also be kept clean to avoid the accumulation of leaves and debris that can obstruct them and create conditions for mosquito breeding. Tires and bottles should be stored in protected places or disposed of properly. For aquatic plants, a weekly water change is recommended, while in pots with saucers, the best practice is to add sand to absorb the accumulated water.
