Abstract
The situation of autochthonous malaria in areas covered by Atlantic Forest involves mildly symptomatic human cases, with the presence of simian plasmodia similar to Plasmodium vivax and Plasmodium malariae and the presence of Anopheles ; being the Anopheles (Kerteszia) cruzii species the only incriminated as vector in such epidemiologic situation . Recent, researches in the area of autochthonous transmission in the south zone of São Paulo (sub -district Parelheiros ) indicated the presence of secondary vector species naturally infected with P. vivax and P. malariae in places modified by human action suggesting the possibility of action of other Anopheles species in the transmission chain of the disease. On the other hand, in the forests of the Serra da Cantareira, in the north of the municipality, it is known the occurrence of simian malaria transmission, but the absence of human cases is curiosity since entomological records report the presence of Anopheles in that area. The goal of this is to continue the entomological survey in the areas already surveyed earlier in Parelheiros, with the aim of finding more evidence of the participation of secondary vectors, as well as establishing the infection rate of Anopheles; in Serra da Cantareira the same process will be realized plus the characterization of anopheles fauna, under different environments. We intend, in both areas, to identify ecological characteristics in preserved and modified environments that may be related to the abundance of Anopheles and dynamics of the transmission of simian and human malaria in two areas of study. It is expected to generate data that may contribute to orientation control measures and surveillance of malaria in the region. (AU)
