Laboratory experiments to determine the duration of the immature stages of Culex pipiens fatigans were carried out because such information is important from the point of view of control by larvicides. At a temperature of 25.1 degrees C+/-0.7 degrees C the mean incubation period is 27.11+/-0.57 hours. Females spend a longer time in the pupal stage than males (34.16+/-0.74 hours and 32.95+/-0.75 hours, respectively, at 28.6 degrees C+/-0.8 degrees C; there is no 24-hour pupating or emerging rhythm. The duration of larval life is longer for the female (135.3+/-4.4 hours) than for the male (118.4+/-2.4 hours). Larvae that take a long time to pupate also take a long time to emerge. Withholding of food for a few hours from first-stage larvae increases the duration of larval life but does not affect that of pupal life. These observations on the differences between the sexes in the duration of larval and pupal life are in agreement with observations made on Aedes aegypti in Uganda.
开展了实验室实验以确定致倦库蚊未成熟阶段的持续时间，因为从使用杀幼虫剂进行控制的角度来看，此类信息很重要。在25.1摄氏度±0.7摄氏度的温度下，平均孵化期为27.11±0.57小时。雌性在蛹期花费的时间比雄性长（在28.6摄氏度±0.8摄氏度时，分别为34.16±0.74小时和32.95±0.75小时）；不存在24小时化蛹或羽化节律。雌性幼虫期的持续时间（135.3±4.4小时）比雄性（118.4±2.4小时）长。化蛹时间长的幼虫羽化时间也长。对一龄幼虫禁食数小时会延长幼虫期的持续时间，但不影响蛹期的持续时间。这些关于幼虫期和蛹期持续时间性别差异的观察结果与在乌干达对埃及伊蚊的观察结果一致。
