The Rôle of Aëdes leucocelaenus in the Epidemiology of Jungle Yellow Fever in Brazil

Aëdes leucocelaenus transmits yellow fever virus readily in the laboratory and has twice been found infected in nature. Except in south Brazil this species is much less common than Haemagogus spegazzinii among day-biting sylvan mosquitos captured with human bait. A. leucocelaenus has a wide distribution throughout the forested area of this country. As a natural vector of jungle yellow fever in the northern part of Brazil it is of secondary importance when compared to H. spegazzinii.
