Resumo: INTRODUCTION: To determine the parity, ovarian development and survival rates of Anopheles albitarsis species, in order to estimate the potential of malaria transmission. METHODS: Two populations of Anopheles albitarsis A and B in an Experimental Farm of S. Paulo State, Brazil were captured during the crepuscular sunset, between 5PM and 8PM, using Shannon traps. Dissections were performed using Polovodova's technique, and the evaluation of follicular development was according to Christophers and Mer's criterion. The Vercruysse method was used to estimate daily survival and we applied Davidson method to determine the duration of the gonotrophic cycle. RESULTS: A total of 2,612 specimens was dissected, of these, 237 of population A and 2,375 of population B. The daily survival rates were 0.5339±0.047 and 0.5566±0.015, respectively, for the populations A and B. The duration of the gonotrophic cycle for population A was 1,990 days and for population B 2,046 days. CONCLUSIONS: The results help to estimate the malaria transmission potential in the region.

OBJETIVO: Conhecer a paridade, o desenvolvimento ovariano e a razão de sobrevivência da espécie Anopheles albitarsis, visando a estimar o potencial de transmissão malárica. MÉTODOS: Duas populações de Anopheles albitarsis, denominadas A e B, foram capturadas na Fazenda Experimental do Instituto Agronômico de Campinas, situada no Município de Pariquera-Açu, Estado de São Paulo. As capturas foram feitas no período crepuscular vespertino das 17h às 20h, utilizando-se armadilha tipo Shannon. As dissecções foram feitas utilizando-se a técnica de Polovodova, e a avaliação do desenvolvimento folicular segundo o critério de Christophers e Mer. Adotou-se o método de Vercrusse para se estimar a sobrevivência diária e o método de Davidson para se determinar a duração do ciclo gonotrófico. RESULTADOS: Foram dissecados 2.612 exemplares, sendo 237 da população A e 2.375 da B. As sobrevivências diárias para as populações A e B foram de 0,5339±0,047 e 0,5566±0,015, respectivamente, e a duração do ciclo gonotrófico para a população A foi de 1.990 dias e para a B de 2.046 dias. CONCLUSÕES: Os resultados contribuem para a avaliação do potencial de transmissão malárica na região. Universidade de São Paulo.
