TRANSMISSION CYCLE OF DENGUE
The mosquito becomes infective when it bites a Dengue patient for a blood meal and the virus from the patient enters the mosquito where it multiplies. Now this infective mosquito when bites a healthy person, it transmits the disease.

Facts about Feeding and resting habits of mosquito transmitting Dengue Fever:
Female Mosquito needs blood meals for development and laying of eggs. In one day it bites 3-5 people to satisfy its blood meals requirement. This is so because the mosquito is Day biter and moment it bites a human being it is moved away by the person so it does not get sufficient time to take Blood meal from the single human body.

FAVOURED BREEDING PLACES
Desert coolers, Drums, Jars, Pots, Buckets, Flower vases, Plant saucers, Tanks, Cisterns, Bottles, Tins, Tyres, Roof gutters, Refrigerator drip pans,�Cement blocks, Cemetery urns, Bamboo stumps, Coconut shells, Tree holes and many more places where rainwater collects or is stored.

B. Environmental Management & Source Reduction Methods
