Anopheles pseudopunctipennis: laboratory maintenance and malaria susceptibility of a strain from El Salvador.

: The techniques involved in the establishment of a strain of Anopheles pseudopunctipennis pseudopunctipennis from El Salvador, Central America are presented. Results of experimental susceptibility studies using coindigenous strains of Plasmodium falciparum and P. vivax as well as P. vivax from Colombia indicated that this anopheline strain does not possess the biologic capability for malaria transmission. The usefulness of biological susceptibility data in establishing the vector status of anophelines, especially in areas with multiple species as potential vectors, is discussed.
