Aedes Aegypti

The dengue mosquito, thus classified, taxonomically (a ?? d ?? of the Greek "odious" and ægypti of the Latin "of Egypt"), is a species from the African continent.

It has spread all over the world, particularly in the hottest and most humid regions of the five continents. The mosquito has quickly adapted to urban areas where it can reproduce and lay eggs in small amounts of clean water in shady places. Females to feed themselves on blood can fly up to 2500 meters.

It is a mosquito that itches during the day, having as preferential victim the human being. Before incubation, the eggs may remain for months waiting for the right moment, when immersed in water, organically poor, the larvae develop rapidly, giving rise to the pupae from which the adult emerges. Only females feed on blood for the maturation of their eggs; this is frequent among all mosquitoes; male feeding is restricted to vegetable and sugary substances.

Aedes aegypti was introduced in the South America through the so-called "slave ships" in the colonial period. There were cases where these ships were left with the crew so reduced because of dengue that they began to wander the seas, constituting the famous "ghost ships." In Brazil, this mosquito was eradicated in the 1950s, however, in the 60 and 70, he returned to colonize Brazil, coming from neighboring countries that had failed to promote its total eradication.

THE FEAR OF GROWING BROMÉLIAS:

The Oswaldo Cruz Institute carried out research that demonstrates the irrelevant role of bromeliads as a probable habitat for the dengue mosquito. During one year, 156 bromeliads of ten species cultivated in the Botanical Garden of Rio de Janeiro were monitored. The study showed a low index of the presence of the immature forms of A. aegypti, generating indications that redirect the work of prevention. "Only 0.07% and 0.18% of a total of 2,816 immature forms of mosquitoes collected in the bromeliads during the one year period corresponded to Aedes aegypti and Aedes albopictus, suggesting that bromeliads do not constitute an epidemiological problem as a focus propagation or persistence of these vectors " said Marcio Mocelin, a biologist at the Institute.

The researcher also says that in April, when there was the highest catch rate, 376 immature forms of mosquitoes were found in the bromeliads examined. Of all of them, only two specimens corresponded to the genus Aedes. The entomologist Ricardo Lourenço, researcher, says: "This research indicates that Aedes larvae, found in bromeliads, should not be over-valued in prevention work and emphasizes that combat should focus on uncovered or poorly capped water boxes, vats, swimming pools and other standing water tanks ", warns.

WHAT TO PLANT TO TAKE AWAY THE MOSQUITO:

Citronella (Cymbopogon citratus) is a natural repellent and can be used in landscaping, since it is a beautiful grass. Another method to control Aedes aegypti is to sow Crotalaria Juncea, a legume, commonly used for green manuring and control of soil nematodes. It attracts dragonflies, winged insects that feed on mosquito larvae. Their eyes are composed of thousands of facets (up to 30,000) and give them a 360-degree field of vision; in a single day can consume other flying insects with up to 14% more of their own weight. Thus, the plant is responsible for the biological control of the dengue transmitting insect
