Both male and female mosquitoes are nectar feeders, but the females of many species are also capable of drinking blood from many mammals. Females do not require blood for their own survival, but they do need supplemental substances such as proteins and iron to develop eggs.

With regard to host location, female mosquitoes hunt their blood host by detecting organic substances such as carbon dioxide (CO2) and 1-octen-3-ol produced from the host and through optical recognition. Mosquitoes prefer some people over others. The preferential victim's sweat simply smells better than others because of the proportions of the carbon dioxide, octenol and other compounds that make up body odor.The powerful semiochemical that triggers the mosquito's keen sense of smell is nonanal.A large part of the mosquito’s sense of smell, or olfactory system, is devoted to sniffing out blood sources. Of 72 types of odor receptor on its antennae, at least 27 are tuned to detect chemicals found in perspiration. In Aedes the search for a host takes place in two phases. First, the mosquito exhibits a nonspecific searching behavior until the perception of host stimulants then it follows a targeted approach.
Just after the rainy season there will be short epidemics of malaria and dengue in the sate of Orissa, hence the malaria/health department carry on update education programmme for the doctors every year.
