The dynamics of transmission of disease agents by vectors depends, in part, on the probability of host-vector contact, which can vary with fluctuations of both host and vector. As important as seasonal variations is 24-hour periodicity in activity. Periodicity in the landing of males and females of Aedes aegypti on man has been assessed by means of catches of 15 hours or longer, with several persons as a bait. The assessments were made in a suburban area of Tanzania and continued throughout one year. Activity was observed to be almost entirely diurnal and diphasic. Whereas the detailed activity pattern of males agreed closely with that found elsewhere in East Africa, that of the females was unusual on account of the symmetry of the morning and afternoon peaks. Possible causes of differences among studies are discussed.
病媒传播病原体的动态变化部分取决于宿主与病媒接触的概率，而这会随宿主和病媒的波动而变化。与季节性变化同样重要的是活动的24小时周期性。埃及伊蚊雌雄成虫落在人身上的周期性已通过以数人为诱饵进行15小时或更长时间捕捉的方式进行了评估。评估在坦桑尼亚的一个郊区进行，持续了一整年。观察到活动几乎完全是昼行性且呈双相的。雄性的详细活动模式与东非其他地方发现的模式非常吻合，而雌性的活动模式则不同寻常，因为上午和下午的高峰对称。文中讨论了不同研究结果存在差异的可能原因。
