Figure 4.

(A) Differences in wing shape between the 2010 field and 2011 field samples of Aedes aegypti. The boxplot represents the significant canonical variate differentiating these samples, although the differences in shape (magnified 5×) are reflected in the landmark comparisons on the right. (B) Scatter plot of the two main canonical variates distinguishing the 2011 field, laboratory reared, and laboratory reared (but field egg derived) samples. The covariates explained 59.0% and 26.4% of the difference in wing shape. Landmark locations (magnified) reflecting differences between the field and laboratory-reared mosquitoes, and the differences between the laboratory-reared and field egg-derived samples are also given.
