Table 3 The infectivity of An. gambiae s.l. mosquitoes reared on unautoclaved clay and sandy soil substrates obtained from mosquito larval habitats in western Kenya and then co-infected with different gametocyte carriers (mean gametocyte density = 173.8 ± 121.4).

  1. Only 8 out of 22 experiments successfully yielded infected mosquitoes. The analysis of mosquito infection was done individually to account for differences in infectiousness among gametocyte carriers and ONLY successful infection experiments have been used in this table.
