Host-seeking activity of malaria vectors, Anopheles arabiensis and Anopheles funestus (Panel A) and Culicines (Panel B) at different times of the night as observed based on half hourly sampling. The peak visiting time for the malaria vector, Anopheles arabiensis occurred in the early hours of the night, i.e. between 7:30 pm and 10:30 pm, followed by a smaller peak around midnight, i.e. between 0:30 am and 2:30 am and in the morning hours, i.e. between 4:30 am and 06:00 am (A). For An. funestus, the second and third peaks were not obvious. Trends for Culex and Mansonia mosquitoes showed the first host-seeking peak at the start of the night, but there were no obvious peaks around midnight or dawn, as in the case of An. arabiensis.
