We colonized Wyeomyia smithii (Coquillett) from southern New Jersey and studied life history characteristics in the laboratory. Males and females showed no significant difference in time spent from first to third instar, but female larvae remained in fourth instar 2.1 days longer than males. At 22 +/- 2 degrees C females emerged 22.6 +/- 3 days after egg hatch; males emerged approximately two days earlier. Male emergence peaked five hours after dawn; females showed a trend to emerge late in the day. Rotation of male terminalia was completed 9 to 11 hours after emergence. Females were capable of mating immediately after emergence. Wyeomyia smithii females laid their first egg batch four to six days after emergence. Females were capable of laying up to seven batches of eggs, however the mean number of eggs per oviposition decreased significantly as the number of oviposition cycles increased.
我们从新泽西州南部采集了斯氏库蚊（Coquillett），并在实验室中研究其生活史特征。从一龄到三龄，雄性和雌性所花费的时间没有显著差异，但雌性幼虫在四龄期比雄性多停留2.1天。在22±2摄氏度的条件下，雌性在卵孵化后22.6±3天羽化；雄性大约提前两天羽化。雄性羽化高峰出现在黎明后5小时；雌性有在一天晚些时候羽化的趋势。雄性外生殖器的旋转在羽化后9至11小时完成。雌性羽化后立即能够交配。斯氏库蚊雌性在羽化后四至六天产下第一批卵。雌性能够产下多达七批卵，然而随着产卵周期数量的增加，每次产卵的平均卵数显著减少。
