Impact of organic solvent fractions from Vernonia amygdalina leaves (100 µg/mL) on sporogonic development. Mosquitoes were membrane fed on blood from three donors with Plasmodium falciparum gametocytaemia values of: a 160 gametocytes/μL, b 184 gametocytes/μL and c 80 gametocytes/μL. Each point represents the oocyst number from an individual mosquito. In a the data point of one midgut on which 94 oocysts were recorded, is not plotted in the graph (largely out of scale).
