Malaria is a major public health problem in Brazil and in the world, with wide distribution in tropical and subtropical regions. One of the main parameters analyzed in the control and monitoring of malaria is the detection of Plasmodium species in vectors capable of infecting humans. The aim of this study was to examine the infectivity of Plasmodium spp. in populations of An. darlingi and An. albitarsis s.l. in neighborhoods located in peri-urban areas of the city of Macapá. In each district were selected two sample points with a minimum distance of 200 m between points. Catches of adult mosquitoes were performed between May 2003 and May 2004 in two weekly intervals in time from 18:30 PM to 21:30 PM, on three consecutive days in peridomestic environments. For detection of Plasmodium spp was used Enzyme Linked Immuno Sorbent Assay (ELISA). The ELISA was performed in 706 mosquitoes were analyzed n = 443 (62.7%) individuals of An. albitarsis s.l. n = 263 (37.3%) of An. darlingi. The result was positive for n = 8 females, n = 7 for An. albitarsis s.l. (87.5%) and n = 1 to An. darlingi (12.5%). The Zerão is the area with the highest risk of transmission. The species An. albitarsis s.l. had the highest rate of infectivity, playing the lead role in the transmission of human malaria in the study areas. While An. darlingi plays a secondary role in transmission. The highest infectivity for the mosquito occurred Plasmodium falciparum.Keywords: Malaria; Plasmodium; Amazon.
