Resumo: To evaluate the monthly frequency of larvae and pupae of Aedes albopictus, Aedes aegypti and other mosquitoe species in tires. and the influence of environmental factors on that.MethodsThe immature stages of mosquitoes were collected monthly from four tires in the municipality of Nova Iguacu. Brazil, from November 1997 to October 1998. The following variables were measured: rainfall, temperature, water volume, water pH. The tires were arranged in a pyramid, one at the base (tire 1) and 3 others (2,3 e 4) laying over it.ResultsWere collected 10,310 larvae and 612 pupae. Aedes albopictus was the most common species in both the larval and pupal stages. Aedes aegypti and Aedes albopictus were collected throughout the year but were more frequent during in the rainy season. The number of Aedes aegypti was significantly, correlated with the temperature, rainfall and water volume of the tires. The correlation between water pH and number of larvae was not significant. Aedes albopictus larvae Were in tires left in the shade.ConclusionsAedes albopictus was more abundant in tires than Aedes aegypti. Discarded fires seem to be an important source of both Aedes species throughout the year. The favored environmental conditions of the tired, such as water volume and exposure to sunlight differ for Aedes albopictus and Aedes aegypti.
