GLASSER, Carmen Moreno  and  GOMES, Almério de Castro. Climate and the superimposed distribution of Aedes aegypti and Aedes albopictus on infestation of São Paulo State, Brazil. Rev. Saúde Pública [online]. 2002, vol.36, n.2, pp.166-172. ISSN 1518-8787.

OBJECTIVE: To study the influence of climatic factors and superimposed distribution of Aedes aegypti and Aedes albopictus populations on their geographic dispersal in the state of São Paulo. METHODS: Data from government agencies on Ae. aegypti and Ae. albopictus foci and their distribution throughout counties of the state of São Paulo year by year, from 1985 to 1995, were obtained. Temperatures and rainfall data were also collected. Two indicators were used: infestation and rate. RESULTS AND CONCLUSIONS: The analysis indicated that the lower the temperature, the slower the geographic dispersal of Ae. aegypti population. This factor predominantly influenced the macro regional dispersal patterns of the species in the state of São Paulo. There was no clear influence of temperature on the dispersal of Ae. albopictus. The influence of rainfall on dispersal patterns was seen only for Ae. aegypti in a state area. No influence was detected on the prior presence of Ae. albopictus on the establishment of Ae. aegypti.
