(A) Difference in melanization efficiency of Acyrthosiphon pisum treated with L-DOPA and α- methyltyrosine; (B) Difference in melanization efficiency of A. pisum from Vicia faba and Trifolium repens; (C) L-DOPA contents from the aphids collected from two diets. Each value represents the mean ± SEM from independent determinations. (D) Wounds (pricking by glass needle) in melanization (arrows); (E) Eyes of embryos (arrow heads); (F) Color information (base on HSB, hue, saturation and brightness) in wound areas; and (G) Relative transcript level of proPO1 and proPO2 after treated by glass needle. Each value represents the mean ± SEM from independent determinations.
