Mosquito survival varies by feeding regime. Mosquitoes that were offered fewer blood meals experienced extended survival, compared to mosquitoes that fed more frequently on the unaltered ‘U’ regime. The y-axis is the proportion of mosquitoes in each treatment alive for each day following the initial blood meal, with day after the initial blood meal shown on the x-axis. Dashed lines represent restricted ‘R’ feeding regimes and solid lines represent unaltered ‘U’ feeding regimes. Controls and heat-killed E. coli challenged mosquitoes are shown in gray and black, respectively. The vertical black line indicates the approximate extrinsic incubation period for P. falciparum at 27 °C [44–47]
