Simian malaria at two sites in the Brazilian Amazon - II. Vertical distribution and frequency of anophline species inside and outside the forest

ABSTRACT

An anopheline survey was carried out in two simian areas in the Brazilian Amazon, Balbina and Samuel, to determine the potencial vectors of Plasmodium brasilianum. The most abundant and/or acrodendrophilic anophelines in the forest and the most likely vector were Anopheles mediopunctatus, An. nuneztovari, An. oswaldoi, An. triannulatus and An. shannoni. An. darlingi and An. marajoara were captured essentially in anthropic habitats outside the forest and are unlikely to be involved in the transmission of P. brasilianum among monkeys within the forest and from monkeys to man in their surroundings in the Amazon.
