  14. 14. THE VECTOR…… • Dengue ,Chikungunya and yellow fever is transmitted by infected female Aedes mosquito • Primarily a daytime feeder and mainly bites in the morning or late in the afternoon • Lives around human habitation • Lays eggs and produces larvae preferentially in artificial containers Although it may feed at any time, the mosquitos periods of peak biting activity are few hours after dawn and in the late afternoon until a few hours after dark. The mosquitos 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 floors, underground tanks, cement tanks and also toilet bowls, as they allow the mosquito to breed right i the il b l h ll h i b d i h in h residence.14 Dr.G.C.Sahu/ROH&FW/GoI/Ahmedabad
