In the laboratory, diapausing Culex pipiens L. females fed on a continuously available sugar source more frequently and longer after adult emergence than did non-diapausing females. They also showed an extended nocturnal pattern of sugar feeding compared with that of non-diapausing females. Differences between diapausing and non-diapausing females with respect to sugar feeding and host-seeking behavior also were related to responses to volatiles from fruit and vertebrate hosts. In this Colorado strain of Cx. pipiens, increased sugar feeding by diapausing females during the first few weeks of adult life may be an adaptation that enhances overwintering survival.
在实验室中，滞育的致倦库蚊雌蚊在羽化后比非滞育雌蚊更频繁且更长时间地取食持续可得的糖源。与非滞育雌蚊相比，它们还表现出延长的夜间取食模式。滞育雌蚊和非滞育雌蚊在取食糖分和寻找宿主行为方面的差异也与对来自水果和脊椎动物宿主的挥发物的反应有关。在这种科罗拉多致倦库蚊品系中，滞育雌蚊在成虫生活的最初几周增加取食糖分可能是一种提高越冬存活率的适应性行为。
