Abstract: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 Agron ômico 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 fe… Show more
“…may be signiÞcantly longer in the laboratory than in the Þeld (4.4 versus 2.4 d, P Ͻ 0.05, respectively). Given agreement between our results and previous reports for Þeld and laboratory conditions (Panday 1977, Charlwood and Alecrim 1989, Rubio-Palis et al 1994and Kakitani and Forattini 2000, there is a biologically signiÞcant difference between the estimates of gonotrophic cycle length based on laboratory or Þeld observations. We found that subsequent gonotrophic cycles were shorter than the Þrst under laboratory conditions, a characteristic suggested previously by Panday (1977).…”

“…albitarsis s.l. under Þeld conditions (2.4 d) was similar to that described by Kakitani and Forattini (2000). Those authors used the method described by Davidson (Davidson 1954) and reported 1.990 d for An.…”

“…The latter authors used capture-release-recapture experiments to determine the duration of the gonotrophic cycle and obtained an average of 2.3 d between the release and recapture of engorged females. Kakitani and Forattini (2000), studying Anopheles albitarsis s.l. of Sao Paulo, Brazil, under Þeld conditions, reported values of around 2.0 d for the gonotrophic cycle duration.…”
Mark-release-recapture experiments were conducted to determine the duration of the gonotrophic cycle of Anopheles albitarsis s.l. in Ribeira Valley, State of Sao Paulo, Brazil. Separate experiments with females collected from the field were followed under laboratory conditions. A mean of 2.4 d was characteristic for the gonotrophic cycle for wild-caught females, whereas 4.4 d was characteristic for females in the laboratory conditions.

“…En estudios epidemiológicos, la intensidad del contacto humano-vector en una población determinada se infiere por medio de la medición del índice de sangre humana, un indicador de su preferencia alimenticia 2-5 y por la medición del ciclo gonotrófico, un indicador de la frecuencia de alimentación, [6][7][8][9][10] puesto que los mosquitos requieren de al menos una alimentación sanguínea para producir cada lote de huevos. Si bien la información en estos indicadores es útil para evaluar la capacidad vectorial de diversas poblaciones de mosquitos, no permite identificar los factores que determinan la intensidad de contacto humanovector.…”

Aos meus pais Vanda e Cristiano, as minhas irmãs Tâmara e Taciane, que sempre me apoiaram nas minhas escolhas, e ao meu pequeno sobrinho curioso Pedro Henrique. Ao meu namorado que sempre foi o meu maior incentivador e companheiro, sempre acreditou em mim, mais do que eu mesma. Ao meu cunhado Cláudio, meus primos Anderson e Adisson, a minha querida tia Lúcia, e todos os familiares que me apoiaram nesta etapa. À minhas amigas especiais Gisele Alves e Gislaine Alves, e toda sua família que aprendi a amar. Aos grandes professores Mauro e Julia do ensino médio, me fizeram ter certeza que a biologia era o caminho certo a seguir. A todos os professores da minha graduação em biologia, que me deram base e ensinos preciosos que me transformaram. À professora Drª. Carmen Taipe Lagos, foi minha professora de zoologia dos invertebrados, e indicou a Faculdade de Saúde Pública da USP, para a continuação dos meus estudos, ótimo conselho.
