Bionomics:
The immatures of braziliensis have been found in clear ponds and clear stagnant swamps with mud bottoms, ponds in cultivated fields and a flooded borrow pit along a stream with stagnant water. Most of the immatures were in full sun or in partial shade, never in entirely shaded areas. All the aquatic habitats contained some type of vegetation; they usually had grassy margins with emergent and floating vegetation, and algae. The water was usually clear, but occasionally turbid. Most sites were in areas of secondary growth such as pastures or forest clearings. (Faran and Linthicum 1981:40)

Medical Importance:
An. braziliensis is not a primary vector of malaria but is capable of malaria transmission under the proper ecological conditions (Deane, Causey and Deane 1948). Normally this species is exophilic and zoophilic; however, in some regions of Amazonia when domestic animals are absent, braziliensis will readily enter houses and bite man. It has been collected naturally infected with Plasmodium spp.
