Three colonized species of the Anopheles culicifacies complex (species A, B
and C) were compared with Anopheles stephensi (control) for susceptibility
to Plasmodium vivax. In feeding experiments involving over 400 paired comp
arisons, the mean number of oocysts, oocyst rate and sporozoite rate were f
ound to be significantly different. Of the test groups, species A had the h
ighest percentage of mosquitoes with oocysts (>60%) and sporozoites (>50%).
An. culicifacies species B were least susceptible, less than 5% had oocyst
s and less than 2% had sporozoites in the salivary glands. The results are
discussed in the light of the vectorial potential of the members of the An.
culicifacies complex observed in field studies.
