A study was conducted at the Firestone Rubber Plantation, Harbel, Liberia, to determine what proportion of the members of the Simulium damnosum complex attracted to a human successfully feed to repletion. The engorgement ratio (proportion of flies landing that feed to repletion) was evaluated at the vector subpopulation level and is expressed as a percentage of flies that land and begin to feed. The data indicate that the S. yahense population at Harbel is relatively inefficient in obtaining a blood meal. Only 25% of the S. yahense attracted successfully fed. Preliminary data from Togo indicate that S. soubrense/sanctipauli, S. damnosum/sirbanum, and S. squamosum present engorgement ratios of 75%, 45%, and 44%, respectively. The impact of feeding behavior on the transmission dynamics of Onchocerca volvulus and the interpretation of annual transmission potentials and control efforts are discussed.
