Sex-specific variations of T. infestans for total body length (a), total body area (b) and wing size (CS) (c) between melanic and non-melanic forms. Box plots show the median (solid line), first and third quartiles. Whiskers indicate the 90th and 10th percentiles. Dots outside whiskers are potential outliers. Key: Left box plots: females. Right box plot: males. Asterisks within graphs indicate significant differences in the ANOVA tests between melanic and non-melanic groups. *P < 0.05, **P < 0.01
