OBJECTIVE   To describe the infestation of the municipalities of São Paulo by the vectors  Aedes aegypti  and  Aedes albopictus,  characterize seasonality and analyze average temperatures and larval densities.    METHODS   We used maps with information on the infestation of municipalities between 1986 and 2015. The analysis of larval density of the species by the Wilcoxon test used the Breteau index values for  Ae. aegypti  and  Ae. albopictus  obtained from the Superintendency for Endemic Diseases Control database. In the seasonal description, arithmetic means of each vector were calculated by month and year. Mean temperature analyses were presented on maps with color gradients.    RESULTS   The state of São Paulo is currently almost totally infested, with co-occurrence of species in 93.64% of the municipalities. The seasonality analysis showed the first quarter as the most favorable period for larval abundance. The increase of mean temperatures in geographical areas coincided with the temporal trajectory of  Ae. aegypti  territorial expansion. The mean larval density found was higher for  Ae. aegypti  than for  Ae. albopictus  (p = 0.00).    CONCLUSIONS   Initially, these Culicidae occupied distinct and opposing areas. Over time, however, co-occurrence showed how great their capacity for adaptation is, even in the face of different social and urban conjunctures. The increase of the mean temperature contributed to  Ae. Aegypti  ’s geographic expansion, as well as to the clearly seasonal profile of both species. In general, larval infestation by  Ae. aegypti  prevailed, which evidenced its competitive superiority. These data provide a better understanding of the dynamics of arboviral transmission in the state of São Paulo and can be used in vector surveillance and control.
