“…Nevertheless, the constitutive cells characterized by an abundant RER coupled with a rich amount of vesicles, which vary in size and include flocculent material, could express some specific metabolic activity. Similar vesicles with muco-substances were described in the cells of MT collecting duct of the nymphal dragonfly Aeshna cyanea by Kukel & Komnick (1989). Even though the mucous secretion was interpreted as a protective device, the actual function of these cells is still unknown.…”

“…Malpighian tubules (MT) have been investigated in depth in many insect groups (Wigglesworth & Salpeter, 1962;Berridge & Oschman, 1969;Sohal, 1974;Green, 1979Green, , 1980Ryerse, 1979;Meyran, 1982;Satmary & Bradley, 1984;Bradley, 1985;Hazelton et al, 1988;Kukel & Komnick, 1989;Dallai et al, 1991;Kapoor, 1994). MT are regarded as typical transporting epithelia involved in secretion and résorption processes.…”

The ultrastructure of the Malpighian tubules of the final instar nymph of the mayfly Baetis rhodani is described. Numerous Malpighian tubules enter the alimentary canal at the transition from midgut to hindgut. Each of them is made up of a cylindrical distal portion and a proximal narrow duct emptying into the gut. At the junction between the two regions, the cylindrical portion enlarges and curves, to continue into the thin duct. The wall of the cylindrical portion consists of primary cells characterized by typical features of the secretory/absorbing epithelia. These cells show a large polytene nucleus, an apical microvillated border, a high number of mitochondria and basal infoldings. The narrow duct is formed of large cells joined by highly convoluted junctions, and their cytoplasm is filled with electron-translucent vesicles. The apical border of the cells of narrow duct lacks microvilli but bears several finger-like extensions. Each narrow duct empties into a canal interposed between groups of gut epithelial cells, which constitute the transition area between midgut and hindgut. The Malpighian tubules of B. rhodani represent an ancestral condition and their structural arrangement provides important information for tracing mayfly evolutionary trends.
