Lignin detection in leaflet galls induced by Bystracoccus mataybae (Eriococcidae) on Matayba guiananeis (Sapindaceae) by fluorescence method with DAPI filter (A,C) and histochemical test with 2% phloroglucinol-HCL (B,D,E). (A,B) Detail of the ostiole on the abaxial surface of a gall with lignified cells (arrow). (C,D) Vascular bundle adjacent to the nymphal chamber surrounded by fibers (arrows). (E) Intense lignification around the nymphal chamber. nc, nymphal chamber; os, ostiole; vb, vascular bundles.
