          Abstract

          Thirty immatures of Anopheles darlingi Root, Anopheles argyritarsis Robineau-Desvoidy and Anopheles rondoni (Neiva & Pinto) (were found in an artificial lagoon situated near Pardo River, in Ribeirão Preto City, State of São Paulo, Brazil. The presence of immatures of Anopheles darlingi breeding in a lagoon is suggestive of the potential capacity of that species to adapt and occupy new habitats and to invade urban areas along the species distribution range and also disperse to new localities.

          Trinta espécimes imaturos de Anopheles darlingi Root, Anopheles argyritarsis Robineau-Desvoidy e Anopheles rondoni (Neiva & Pinto) foram encontrados em lagoa artificial situada nas proximidades do Rio Pardo, em Ribeirão Preto, Estado de São Paulo, Brasil. A presença das formas imaturas de Anopheles darlingi criando-se em lagoa artificial sugere que a espécie tem potencial tanto para se adaptar e ocupar novos habitats como para invadir áreas urbanas ao longo da distribuição geográfica e também de se dispersar para novas localidades.

              Malaria vectors, epidemiology, and the re-emergence of Anopheles darlingi in Belém, Pará, Brazil.

              An evaluation of malaria transmission and epidemiology in the Amazonian city of Belém over the last 70 years shows that (1) Anopheles darlingi, reported to be eradicated in 1968, reappeared in the mid 1990s, with a marked increase in abundance between 1997 to 1999 in two of three districts sampled; (2) An. darlingi and An. aquasalis are each implicated in current malaria transmission in different districts of the city; (3) mosquito species diversity (in Anopheles subgenus Nyssorhynchus) has increased from two in the 1930s to six in the 1940s to 10 in the 1990s; (4) there is no overall correlation between malaria case incidence and human population size from 1940 to 1996 in Belém; (5) however, the total number of malaria cases has increased significantly since the late 1970s and over the short term from 1993 to 1999; and (6) interestingly, the short term increases are due solely to cases of Plasmodium vivax infection; cases of P. falciparum malaria are declining (significantly for Pará state only). The reappearance of An. darlingi may be a result of the continued expansion of Belém into the surrounding forest in the 1990s. In the absence of preventative measures, we predict an increase in local outbreaks of malaria in the DAENT and DAICO districts where the population sizes of An. darlingi are increasing.
