Efeitos da temperatura no ciclo de vida, exigências térmicas e estimativas do número de gera??es anuais de Aedes aegypti (Diptera, Culicidae)

摘要

The present work aims at estimating, based on a biological study, the thermal exigencies to the development and the number of generations per year of Aedes aegypti (Linnaeus, 1762) (Diptera, Culicidae) in field. The life cycle of the A. aegypti populations has been studied at constant temperatures of 18, 22, 26, 28, 32 and 34 ± 2oC, and 12 hours photophase. The low threshold temperature of development (Tb) and the thermal constant (K) have been determined. The number of generations per year in laboratory and field has also been estimated. The favourable temperature to the A. aegypti development its between 22oC and 32oC, and to the longevity and fecundity A. aegypti adult its between 22oC and 28oC. The egg to adult basal temperature, thermal constant and the number of generations in field were, in order, 11.33; 8.99 and 13.61 oC, 192.3; 213.2 and 116.5 graus-days, and 23; 24.6 and 30.3 generations to A. aegypti populations from Boqueir?o (07o29'27''S, 36o08'09''W), Campina Grande (07o13'32''S, 35o54'15''W) and Remígio (06o58'1''S, 35o47'29''W).
