Objective:

To characterize the historical series of the number of cities infected by Aedes aegypti and by Aedes albopictus in the state of São Paulo (ESP), from 1986 to 2015. To analyze their seasonality, average temperatures, infestation indicators of each species, and to verify their spatial interdependence in Metropolitan Region of the Vale do Paraíba Paulista (RMVP). Material and

Methods:

The data from entomological surveillance actions were obtained using the Breteau index (IB), from the database of the superintendence of Control of Endemics (Sucen). The arithmetic means were calculated by month and year and, then, analyzed by the Wilcoxon test. The temperature maps were obtained at the National Institute of Meteorology (NIMET). For the geospatial analysis of the species in the Metropolitan Region of the Paraiba Valley (RMVP), Moran global indicator (I) and Kernel density estimator (K) were used.

Results:

The state of São Paulo demonstrated to be almost totally infected by these two species, with record of coexistence in 93,64% of the cities. The geographic track of these vectors species was antagonistic, but the overlap prevailed over time, and always with differences in larval abundance. The seasonality highlighted the first quarter of every year as the most favorable time. The elevation of average temperatures and the expansion of the occurrence of Ae. aegypti were coincident, demonstrating their contribution in the dispersion of this species. In the ESP, the estimate of Ae. aegypti larval density was 4.27 times higher than that observed for Ae. albopictus. For the RMVP, it could be verified the decline of the precursor species, Ae. albopictus, after the establishing of the Ae. aegypti. The Moran global index (I) did not reveal the spatial dependency 9 among the analyzed cities. The infestation intensity by Kernel indicated a heterogenic distribution with critical areas for both species.

Conclusion:

Ae. aegypti and Ae. albopictus presented, initially, occupancy in distinct and opposite geographic areas, but with the passage of time it was observed variation in the pattern of infestation and coexistence of the species, where Ae. aegypti was the predominant species, which suggests its competitive superiority in ESP. Both vectors showed distinctly seasonal behavior, with higher abundances in the warmer months. The elevation of average temperatures and the expansion of the Ae. aegypti occurrence, showed its contribution in the dispersion of this species. The absence of the infestation autocorrelation in the cities of the Metropolitan Region of the Paraiba Valley showed spatial independency, being, therefore, dependant of its local characteristics. The Kernel density estimator pointed conglomerates of strategic cities for the reduction of the vector population density. (AU)
