5. NAME : AEDES AEGYPTI Age: 14 to 21 days Place of Birth : Clean stagnant Water Gender : Female Address : Closets and other dark places avenue, Cool and Shaded City Breed: Any water-catching or storage containers in shaded or sunny places. Spread : I can spread the virus if I bite an infected person, but my partners can’t. Likes in Life : I’m favored of breeding places are- Barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks, cisterns, bottles, tins, tires, pans, plant saucers and roof gutters, refrigerator drip pans, catch basins, drains, soak-away pits, cement blocks, cemetery urns, plant leaf axils, bamboo stumps, tree cavities and a lot more places where rainwater collects or is stored. Motto in Life:

6. Do you know…..  Only the female Aedes mosquito feeds on blood. This is because they need the protein found in blood to produce eggs. Male mosquitoes feed only on plant nectar.  On average, a female Aedes mosquito can lay about 300 eggs during her life span of 14 to 21 days.

7. Life Cycle of the Aedes mosquito 1-2 days Stagnant water Pupae 4-5 days LarvaeEggs 2-3 days

8. Transmission Mosquito bites and sucks blood containing the virus from an infected person. Virus is carried in its body. And passes the virus to healthy people when it bites them.
