Aedes aegypti and Aedes albopictus are the most important arbovirus vectors in the worldwide. The aim was to evaluate the population density of Aedes spp. in cemeteries. The growth of the mosquito population is associated with routine human (anthropic) actions, which enable the existence of artificial oviposition sites and allow an increase in their infestation. The study was conducted from August 2007 to August 2008 and 144 ovitraps were distributed in four cemeteries. A total number 450,539 eggs were collected. The percentage of positive traps (POI) was 100%. The highest value was found in the Guadalupe cemetery, 286,893 eggs (63.4%, p < 0.001), compared to the lowest value in the São Francisco cemetery, 30,601 eggs (6.72%). The pluviometric indexes in the months evaluated showed different monthly distribution patterns, with peaks in August (223.7 mm3) in the year 2007, and between March (395.4 mm3) and May (415.7 mm3) 2008. The general analysis shows that in three of the four cemeteries the presence of the two species Ae. aegypti (56.2%) and Ae. albopictus (43.8%), has no significant difference (p = 0.1250). Both species were present, showing the clear adaptation of Ae. albopictus to urban areas. Ae. aegypti was predominant in all of the cemetries with the exception of the Parque Metropolitano cemetery. The present study demonstrated a high infestation of Ae. aegypti and Ae. albopictus populations in all the cemeteries, indicating the need to adopt complementary measures in areas considered as a strategic point, to improve the surveillance and control of these species.
