Box plots of silhouette coefficients and bar graphs of percentage of mosquitoes, respectively, showing the quality and distribution of laboratory-reared and wild mosquitoes in clusters after <i>k</i>-means analysis.

<p>A and B, number of mosquitoes per age was not controlled (<i>p</i> = 0.01), C and D, age structure of laboratory-reared mosquitoes was standardized to match the published age structure of wild mosquitoes (<i>p</i> = 0.57), E and F, laboratory-reared mosquitoes at 3, 5, and 25-day old were not included in the analysis (<i>p</i> = 0.26). <i>P</i> stands for p value and N for the number of mosquitoes.
