Abstract

The Culicidae family, represented by mosquitoes has significant biodiversity and important role in the transmission of pathogens to humans, domestic and wild animals. Most females feed on blood of many vertebrate hosts. The remaining forest fragments in São Paulo, as the Conservation Units State Park of Cantareira and APA Capivari-Monos, are home to variety of mosquitoes important for public health and there are positive cases for malaria in primates and humans. Knowledge of the bio-ecology of mosquitoes evidence that some species are acrodendrophilic, while others inhabit closer to the ground level, and also for some species, the vertical elevations of vegetation gradient are indifferent. In this context, it is important to look beyond the vertical stratification, the eating mosquito behavior because their blood supply sources are significant parameters to understand their adaptations for the evaluation of their vectorial capacity and the understanding of disease transmission cycles. Given the important factor of the presence of mosquitoes in these areas and the proximity of man to forests, this study aims to investigate the variations of mosquitoes assemblies in different strata of vegetation and its relationship with animal reservoirs in these areas with varying degrees of human interference, measuring variations in the richness, abundance and composition of mosquitoes in ground height and the canopy environments in urban, rural and wild features in the two areas of study for 14 months, checking the eating habits of engorged mosquitoes collected in different strata of vegetation within each target environment, pointing mosquito species that can serve as a bridge for the pathogen circulation and analyzing how changes in the environment can influence the diversity and mosquito eating habits.
