Abstract

A multiplex PCR assay has been developed for detection of Anopheles fluviatilis cryptic species, their human host preference, and Plasmodium falciparum presence in the mosquito. PCR conditions were optimized using primer sets specific for A. fluviatilis cryptic species, Homo sapiens, and P. falciparum and evaluated with field-collected mosquitoes. A unique mosquito processing method was used for screening P. falciparum carrying capacity and human host preference of A. fluviatilis mosquitoes in first-round multiplex PCR. The vectorial status of the mosquito for P. falciparum parasite was confirmed in second-round PCR. Of the 121 collected mosquitoes, 92 were of S type, 26 of T type, and 3 were of other types. Human host preference was dominant in S type, of which 4% were P. falciparum sporozoite positive. This assay and processing method can also be used to evaluate vector competence of other anophelines.
