          Abstract

          Objetivou-se comparar o ciclo de vida e estimar, com base em tabelas de vida de fertilidade, os padrões de fertilidade de populações de Aedes aegypti (L.). Os ciclos de vida foram estudados a 26 ± 2ºC, e fotofase de 12h, avaliando-se, diariamente, o período de desenvolvimento e a viabilidade das fases de ovo, larva e pupa, e a longevidade e fecundidade dos adultos e elaborando-se tabelas de vida de fertilidade. As durações das fases de ovo, larva e pupa, variaram de 3,9 a 4,5 dias, 6,4 a 8,3 dias e de 2,0 a 2,5 dias, respectivamente. Os parâmetros de tabela de vida para A. aegypti de Brejo dos Santos, Boqueirão, Itaporanga e Remígio foram, respectivamente: Ro = 104,03, 84,58, 113,37 e 91,18; rm = 0,92, 0,78, 0,89 e 0,88; e lambda = 2,50, 2,18, 2,43 e 2,41. As populações de Brejo dos Santos e Itaporanga mostraram o maior potencial de crescimento em relação às demais populações. Os resultados mostram que há um padrão diferenciado de crescimento e potencial biótico para as populações de A. aegypti provenientes de diferentes municípios da Paraíba.

          The present work aims at comparing the life cycle and estimating, based on life tables, the patterns of fertility of populations of A. aegypti (L.). The life cycles were studied at the temperature of 26 ± 2ºC, and 12h photophase. The development period, egg viability and larval and pupal survival were evaluated daily as well as adult longevity and fecundity. Tables of fertility life were built. The durations of egg, larva and pupa stages varied from 3,9 to 4,5 days, from 6,4 to 8,3 days and from 2,0 to 2,5 days, respectively. The life table parameters for A. aegypti from Brejo dos Santos, Boqueirão, Itaporanga and Remígio, being, respectively, Ro = 104,03, 84,58, 113,37 and 91,18; rm = 0,92, 0,78, 0,89 and 0,88; and lambda = 2,50, 2,18, 2,43 and 2,41. The populations of Brejo dos Santos and Itaporanga had the biggest potential of growth in relation to the other populations. The results showed a differentiated pattern of growth and a biotical potential in the populations of A. aegypti originated from different municipal districts of the state of Paraíba.
