Resumo: OBJECTIVES: To study the longevity of Ae. albopictus populations in rural and urban areas in two different feeding conditions and to assess their physiological age and reproductive history. METHODS: Ae. albopictus larvae were collected in the Paraíba Valley, (urban area) and Ribeira Valley (rural area), São Paulo State, Brazil. In the laboratory, females were fed with sugar or blood and monitored daily. The day of death of each mosquito and other reproduction related characteristics were registered. Ovaries were dissected using Polovodova techniques and follicular development was examined according Christophers and Mer. Life tables were created and statistics analysis was performed for survival rates. Data analysis was carried out using Stata 7.0. RESULTS: Gonotrophic discordance was seen in both populations. Parous females developed terminal sacs. Nulliparous females had normal ovaries and in some cases dilatations were seen. Females fed with sugar showed higher survival rates. Statistical difference in survival rates was not observed in the populations of both areas. CONCLUSIONS: Parity status and physiological age of Ae. albopictus were not described using ovarioles analysis because they formed terminal sacs instead of dilations. Longevity of Ae. albopictus females was influenced by the food provided.

OBJETIVOS: Estudar a sobrevivência de populações de Aedes albopictus de ambientes rural e urbano, em diferentes condições de alimentação, e analisar sua idade fisiológica e a história reprodutiva. MÉTODOS: Foram coletadas larvas de Ae. albopictus no Vale do Paraíba (localidade urbana), e no Vale do Ribeira (localidade rural), Estado de São Paulo. As fêmeas que emergiram foram alimentadas com açúcar ou com sangue e observadas diariamente anotando a data da morte de cada uma e outras variáveis relacionadas com a reprodução. Os ovários foram dissecados seguindo a técnica de Polovodova, e a avaliação do desenvolvimento folicular segundo Christophers e Mer. Foram construídas tábuas de vida e analisadas estatísticamente as taxas de sobrevida. Para análise dos dados foi utilizado o Stata 7.0. RESULTADOS: Foi observada discordância gonotrófica nas duas populações de Ae. albopictus. As fêmeas oníparas desenvolveram sacos terminais. As nulíparas apresentaram ovários normais e em alguns casos foram observadas dilatações. As fêmeas alimentadas com açúcar apresentaram maiores taxas de sobrevida. Não foi detectada diferença estatística na taxa de sobrevida entre as duas populações avaliadas. CONCLUSÕES: A idade fisiológica e o estado de paridade de Ae. albopictus não foram definidas pela análise dos ovaríolos porque estes apresentaram sacos terminais em vez de dilatações. O tipo de alimento ingerido influenciou na sobrevivência das fêmeas de Ae. albopictus. Universidade de São Paulo.
