Rate of incubation in Ae. aegypti (blue) and Ae. albopictus (orange). The data from each individual assay are shown by blue triangles for Ae. aegypti (n = 373) and orange circles for Ae. albopictus (n = 125). The fitted lines for rate of EIP completion for each experiment are shown in faded blue lines for Ae. aegypti and faded orange lines for Ae. alboipictus. The mean fit for each species is shown in thick solid blue (Ae. aegypti) and orange/brown (Ae. albopictus) lines. The black dotted line indicates the point at which 50% of the population will have completed incubation, which is equivilent to the mean EIP.
