A transect of infusion-baited oviposition tubs was used at the Orange County (CA) Vector Control District facility to determine the circadian periodicity and the influence of urban habitat factors, such as buildings, ornamental plantings, and mercury vapor lights on Culex quinquefasciatus oviposition activity. The peak oviposition activity occurred during the first 2 h after sunset. Nearly 80% of egg rafts deposited were laid within the first 4 h after sunset and no morning ovipositional peak was detected. Urban and physical habitat factors considered had no effect on tub selection by ovipositing females. Linear analysis indicated that eggs were laid randomly among tubs. Eighty-eight percent of the rafts collected were Cx. quinquefasciatus. The remaining egg rafts were laid by Culex tarsalis, Culex stigmatosoma, and Culieseta incidens.
在加利福尼亚州橙县病媒控制区的设施中，使用了一排装有诱卵液的产卵桶，以确定致倦库蚊产卵活动的昼夜周期性以及城市栖息地因素（如建筑物、观赏植物和汞蒸气灯）的影响。产卵活动高峰出现在日落后的前2小时内。近80%的卵块是在日落后的前4小时内产下的，未检测到早晨的产卵高峰。所考虑的城市和物理栖息地因素对产卵雌蚊选择产卵桶没有影响。线性分析表明，卵在桶之间随机产下。收集到的卵块中有88%是致倦库蚊的。其余的卵块是由西氏库蚊、斑跗库蚊和环跗库蚊产下的。
