Hut entry and exit by Anopheles gambiae and Anopheles funestus in an unsprayed village near Kaduna in Northern Nigeria.
Hut entry and exit by An. gambiae and An. funestus were studied in an unsprayed village near Kaduna in Northern Nigeria. A high turn-over of indoor resting mosquitoes of all blood digestion stages was noted throughout the night. The behaviour of both species was similar. The entry pattern was more uniform than the exit which showed two distinct peaks around sunset and after midnight. Most of the daytime resting mosquitoes left the huts during the first hour after sunset, and therefore the mosquitoes escaping during the subsequent hours of the night were mainly those that had entered the same night and spent only a limited period inside the huts. The significance of the movement of mosquitoes is discussed in relation to entomological evaluation of the impact of residual insecticides.
