FIGURE 1 in The histo structure of galls induced by aphids as a useful taxonomic character: the case of Rectinasus (Hemiptera, Aphididae, Eriosomatinae)

FIGURE 1. Galls induced by Rectinasus buxtoni. Microscopic structure. a Transverse section of the wall of the gall. Two vascular bundles are observed, one closer to the outside (Uvb) and the other closer to the inside of the gall (Lvb). Specifically, going from the outside (A) to the lumen (L) of the gall, the following is observed: epidermis-air (ea), storage parenchyma (pa), upper vascular bundle (Uvb), storage parenchyma, lower vascular bundle (Lvb), and epidermis-lumen (el). b–e Epidermis-air. b Uniseriate epidermis-air with thickened cuticle (c). Below storage parenchyma (pa) is observed, many cells of which have tannin inclusions. c View of the outer surface the gall. Between the epidermal cells a few stomata (s) are observed. d Detail of the foregoing. A stoma (s) and the presence of epicuticular waxes are observed in the epidermal cells. e Detail of the epicuticular waxes. f–i Vascular bundles. The vascular bundles are seen to be facing each other: the xylem of the upper bundle f–g is facing the xylem of the lower bundle h–i. f–g Upper vascular bundle. Xylem cells in f are the only ones that polarize light in g. h–i Lower vascular bundle. Xylem cells in h are the only ones that polarize light in i. The phloem is oriented towards the lumen (L) of the gall. j Detail of a vascular bundle: Closed collateral vascular bundle. Very characteristic of the vascular bundles of Pistacia sp. (and of the galls) is the presence of intraphloematic schizogenous ducts (sd). k–l Interior surface of the gall. k The interior surface of the gall has conspicuous dimples. l Detail of the foregoing. a b f h Safranin-Fast Green.

Abbreviations: A outside of the gall, c cuticle, ea epidermis-air, el epidermis-lumen, L lumen of the gall, Lvb lower vascular bundle, pa storage parenchyma, ph phloem, s stoma, sd intraphloematic schizogenous duct, Uvb upper vascular bundle, x xylem.
