Rapid evaluation of malaria parasite density and standardization of thick smear examination for epidemiological investigations.

abstract：:In the irrigated zones of North-eastern region of Afghanistan malaria transmission is sustained by A. pulcherrimus and A. hyrcanus despite many years of DDT spraying. A. hyrcanus is an exophilic and exophagic mosquito, strongly resistant to DDT. A. pulcherrimus is still largely susceptible to the insecticide but seems...
