Impact of Wolbachia wAlbB strain on wing size of Ae. aegypti females (a) and males (b) at the F8 generation. Similar lowercase letters above each box indicate that these is no significant difference (P > 0.05) between the groups by Wilcoxon–Mann–Whitney test at the 95% confidence interval of the difference. P-values are given at the top of each graph. The box-and-whisker plots represent the observed distribution of wing length in Wolbachia-infected and non-infected groups. The bottom and top of the box represent the first (lower) and third (upper) quartiles (25–75th percentile), respectively, and the middle line within each box indicates the median. The cross represents the mean. The vertical lines (ends of the whiskers) extend to the minimum and maximum values
