The ultrastructural studies of the epithelial cells of the anal papillae of larvae of Aedes togoi were made by electron microscope. The materials were reared in different salinities for 120 generations. The epithelial cells of the anal papillae of the larvae reared in 100% sea water or fresh water have infolded and rough structures (Figs. 5-6). However, in 200% and 250% sea water, the structures become extremely fine. The structure is complicated, consisting of overlapping slices with a great number of mitochondria. The mitochondria are densely distributed, like the bubbles of a crepe cake (Figs. 1-4). In the larvae of Aedes togoi, the denser the salinities, the more complicated the structures of the epithelial cells of anal papillae. We deduce from this observation that the anal papillae of Aedes togoi serve as an organ of salt regulation system.
