Micrographs of the salivary gland in adult male C. megacephala. (a) Light micrograph of the whole excised alimentary canal showing salivary glands (arrow) situated in the foregut region. Bar = 10 μm. (b) Light micrograph indicating a translucent single median deferent duct (dd) bifurcated into two long, narrow efferent ducts (ed) connected to the coiled tubular glands. Bar = 5 μm. (c–e; SEM micrographs) (c) Coil salivary gland at one side. (d) Intense tracheal ramification onto the gland surface. (e) Ruptured gland exhibiting numerous rounded vesicles that are probably secretory granules.
