Infectivity of two strains of Plasmodium vivax to Anopheles albitarsis mosquitoes from Colombia.

Anopheles albitarsis obtained from Villavicencio, Colombia, were colonized in the laboratory using force-mating techniques. Laboratory reared mosquitoes were allowed to feed on Aotus monkeys infected with the Salvador II or the Rio Meta strains of Plasmodium vivax from El Salvador and Colombia, respectively. In comparison with other species, the An. albitarsis were less susceptible than Anopheles freeborni, Anopheles culicifacies and strains of Anopheles albimanus from El Salvador, Panama and Colombia and more susceptible than a strain of An. albimanus from Haiti.
