Intracellular localization of Zn in the alimentary canal, silk gland, fat body, ganglion and muscle of 72-hr-old silkworm larvae, at the 5th instar, were investigated by electron microscopic histochemistry 24 hours after the administration of ZnCl_2. Zn incorporated was observed as Zn particles located specifically on the nuclei and mitochondrion of cells in various tissues and organs. In the ganglion, Zn particles could be seen in the cortex zone, but not in the medulla zone. Zn particles were also concentrated on the outer surface of the trachea (epithelial layer)penetrating the basement membrane and in the intercellular space in various tissues. These spaces seemed to bear a close relation with the transportation of Zn into the cells. The mechanism of Zn incorporation was discussed.
