Figure 4.

Effect of increasing population size and food availability (DD = doubled diet) on the median length of the second antennal segment of female and male Lygus hesperus that had recently molted into adults. The boxplots also indicate the interquartile range, the largest non-outlier value (whiskers), and the outliers (circles). Significant differences among groups are indicated by different letters (p < 0.05, Dunn's multiple comparison test after ANOVA). Sample sizes are given. For each test condition, females had significantly shorter segments than males (Mann-Whitney test, p < 0.01). High quality figures are available online.
