本工作旨在估算埃及伊蚊（Aedes aegypti（L.）在自然条件下。生活史研究表明，A.在18、22、26、30和34 ℃的恒温条件下，对埃及伊蚊种群进行了12小时的恒温研究。每天评估发育期、卵活力、幼虫和蛹存活率以及成虫寿命和繁殖力。测定了显影的低阈值温度（Tb）和热常数（K）。并估算了该虫在室内和田间的年发生数。A.埃及伊蚊发育的温度在21摄氏度到29摄氏度之间，而其寿命和繁殖力的温度在22摄氏度到30摄氏度之间。卵至成虫的基温、积温常数和田间世代数依次为9.5、8.5、3.4、7.1、13.5 ℃，244.5、273.9、298.51、280.9和161.8度日;在博凯劳、布雷霍-多斯桑托斯、大坎皮纳、伊塔波朗加和雷米焦的群体中分别出现21.9、23.8、24.2、21.1和22.1代。
The present work aimed at estimating the thermal requirements for the development and the number of generations per year of Aedes aegypti (L.) under natural conditions. The life cycle of A. aegypti populations was studied at constant temperatures of 18, 22, 26, 30 and 34 degrees C, and 12h photophase. The development period, egg viability and larval and pupal survival were evaluated daily as well as adult longevity and fecundity. The low threshold temperature of development (Tb) and the thermal constant (K) were determined. The number of generations per year in laboratory and field were also estimated. The favorable temperature to A. aegypti development is between 21 degrees C and 29 degrees C, and to longevity and fecundity is between 22 degrees C and 30 degrees C. The egg to adult basal temperature, thermal constant and the number of generations in field were, in order, 9.5, 8.5, 3.4, 7.1, 13.5 degrees C; 244.5, 273.9, 298.51 280.9 and 161.8 degree-days; and 21.9, 23.8, 24.2, 21.1 and 22.1 generations in populations from Boqueirao, Brejo dos Santos, Campina Grande, Itaporanga and Remigio.
