Abstract

|
In the suboesophageal ganglion of Bombyx mori, the diapause regulator producing cells which may give an information to the diapause factor cells were found by means of electron microscopy. The diapause regulator producing cells had larger granules (2000 to 5000 A in diameter) than did the diapause factor cells which were partially surrounded by the formers. Highly electron-dense material of lysosome in the diapause regulator producing cells was observed in the diapause-egg producer but such lysosomes were not in the non-diapause egg-producer. It was found that many cytoplasmic granules fuse with lysosome, and smaller granules come out of lysosomes. Some implications of the diapause factor cell and the diapause regulator producing cell were discussed.
