Blood fed mosquitoes were collected inside four bed nets in which mother/child pairs, having different haptoglobin types, slept. The bloodmeals were analysed by gradient gel electrophoresis to determine on which person the mosquitoes had fed. The results suggest that the mothers are fed on much more than babies by both Anopheles gambiae s.l. and Culex fatigans. In one hut at least 15.2 per cent of the mosquitoes had taken all or part of their bloodmeal elsewhere. A greater number of double feeds were detected from engorged Cx. fatigans (12.6%) than An. gambiae s.l. (2.7%).
