Why do the galls induced by Calophya duvauae Scott on Schinus polygamus (Cav.) Cabrera (Anacardiaceae) change colors?

► Red galls were more numerous than the green ones. ► Anthocyanins and chlorophylls were reduced in galls. ► Color changes are stimulated by the balance chlorophyll-anthocyanin. ► The green color in galls is consequence of the death of the gall inducer.
