Development times and survival of immatures and reproductive diapause of adult females of Culex tarsalis, Cx. restuans and Culiseta inornata were investigated from hatching to adult emergence at 15, 20 and 25 degrees C in the laboratory and at natural temperatures and photoperiods in southern Manitoba. Based on patterns of oviposition in artificial pools operated from mid-April to the end of September and development time of the immature stages, 3 generations of Cx. tarsalis, Cx. restuans and Cs. inornata were possible in 1980 and 1981. In 1981, 70% of field-reared Cx. tarsalis females emerging in mid-August were in diapause. Field-reared Cx. restuans and Cs. inornata entered reproductive diapause 2-3 weeks later than Cx. tarsalis.
在实验室中，于15、20和25摄氏度条件下，以及在马尼托巴省南部的自然温度和光周期条件下，对致倦库蚊、环跗库蚊和无饰库蚊未成熟阶段的发育时间、存活率以及成年雌蚊的生殖滞育进行了研究，观察从孵化到成虫羽化的全过程。根据4月中旬至9月底运行的人工水池中的产卵模式以及未成熟阶段的发育时间，1980年和1981年致倦库蚊、环跗库蚊和无饰库蚊可能出现3代。1981年，8月中旬羽化的野外饲养的致倦库蚊雌蚊中有70%处于滞育状态。野外饲养的环跗库蚊和无饰库蚊进入生殖滞育的时间比致倦库蚊晚2至3周。
