In the eri-silkmoth, the sex pheromone production and its secretion show the daily periodicity. The fine structure of the alluring gland was examined with an electron microscope in relation to this phenomenon. The surface of the gland cells is covered with the cuticle with many processes. The pore canals exist in the cuticle. In the pore canals of the endocuticle, the arborescent microtubules with the dense substance, is observed clearly. In the upper end of the gland cells indicat the sinuatoconvex. In this sinus parts, the inosculated microvilli are developed, and this convex are connected to the basal parts of the pore canals. Besides, the basal part cell membrane shows the infolding. The nucleus has an extremely irregular contour surface. The mitochondria in the upper part, the golgi vesicle and the cytoplasmic microtubules are especially developed in the gland cells. The tops of the cytoplasmic microtubules are assembled to the convex parts of the upper end of the gland cells. We consider that the cytoplasmic microtubules are in connection with the microtubules (in the pore canals) or the pore canals. In the cytoplasma, the lipid droplets and micro dense granules exist at night, but most of these matrices disappeare in the day light. Therefore, we think that the sex pheromone or its carrier is produced with these substances.
