Fig. 1. The effect of malaria infection on the occurrence of apoptosis and resorption of follicles in ovaries from Anopheles stephensi. Mean percentage of follicles per ovary stained with Neutral Red and thus resorbing; uninfected mosquitoes (filled squares), infected mosquitoes (filled columns) and/or containing apoptotic nuclei stained with Acridine Orange; uninfected mosquitoes (open squares), infected mosquitoes (open columns). Sample size, 20 in each case. Values are means + S.E.M. A significant difference occurred between resorption and apoptosis in infected females at one time point (^*P<0.05).
