Relationship between number of oocysts and blood meal size in (a) the isogenic strain experiment and (b) cumulative dataset for the three wild mosquito experiments. General additive models were fitted to each dataset using all mosquito replicates independently of their insecticide resistant status. Squares represent the mean number of oocysts for each haematin value (haematin values were rounded up to the nearest integer). Bars above and below the means represent the standard errors of the mean. The fitted curve corresponds to the predicted values arising from the statistical models.
