Abstract

The 3 laboratory-colonized malaria vectors, i.e., Anopheles stephensi, An. sundaicus, and An. fluviatilis, were studied for their comparative susceptibility to Plasmodium vivax sporogony. There was no significant difference in oocyst and sporozoite recruitment by these 3 species, whereas the geometric mean (GM) of the oocyst number per midgut was significantly lower in An. fluviatilis as compared with that in the other 2 species. There was no difference in the GM of oocyst between An. stephensi and An. sundaicus. Adaptability to laboratory conditions and susceptibility to plasmodial infection suggest that An. fluviatilis and An. sundaicus can also be used as a vector model for vector-parasite interaction studies.
