title: Urban malaria vector biology.
abstract: One of the main reasons for the set-back in the urban malaria control programme is the peculiar biobehaviour of the principal urban malaria vector Anopheles stephensi. Certain relevant facts such as incrimination as the vector of malaria, sibling or biological species, resting habitat, manlanding behaviour, seasonal prevalence, blood meal analysis, longevity, parity status, daily survival and mortality rates of adults, breeding habitats and vertical distribution of larvae of An. stephensi have been discussed. Determination of density of the vector using various parameters and their relation to malaria endemicity in an urban situation have been reviewed. An. stephensi has become resistant to DDT, HCH, malathion and propoxur in many places in India. Hence for control source reduction, use of predators such as fish and biolarvicides such as Bacillus thuringiensis var israelensis H14 and B. sphaericus, personal protection, i.e., use of appropriate clothing, bed nets, indigenous repellents, etc., information, education and communication (IEC) are to be stressed.
