Mosquito infection outcomes in matched colony and wild An. arabiensis membrane-feeding experiments. The proportion of mosquitoes that were fully-fed on the patient blood through the membrane feeder (a) with the resulting proportion of infected mosquitoes (b) are indicated together with the log₁₀-transformed oocyst intensity per midgut of infected mosquito (c) for colony (filled dots) and wild-caught (unfilled dots) mosquitoes. d The association between the proportion of infected mosquitoes (Y-axis) and log₁₀-transformed gametocyte densities/µl (X-axis) measured by microscopy for colony (filled dots) and wild-caught (unfilled dots) mosquitoes. Lines in a–c indicate median values and 25th and 75th percentiles. The asterisks in a indicate a statistically significant difference between the wild and colony mosquitoes (P < 0.001)
