| 内容記述 | The effect of the electrical stimulation on the termination of the diapause of the pupa was investigated in a giant silkmoth, Samia cynthia pryeri (Philosamia cynthia cynthia). It has been known in this insect that for the development of the pupa the long period of exposure to the low temperatures before the incubation is required. It has also known that the diapause of the pupa is under the direct control of the activity of the prothoracic glands and then the activity of the prothoracic glands itself is governd by the activity of the neurosecretory cells of the pupal brain. The following results were given from these experiments. (1) The period between the beginning of the incubation and the activation of the neurosecretory cells of the chilled pupa was shortened by the electric stimulation. (2) The brain of the non-chilled pupa was brought to such an activated state by the electrical stimulation as the diapausing non-chilled pupa transplanted the brain of the stimulated pupa initiated the further development. In these experiments a possibility of the direct activation of the prothoracic glands to the electric stimulation seems to be excluded from the fact that no effect was brought out by the stimulation of the pupa extirpated of the brain before the stimulation. A relation was found between the electrical activity of the pupa and the results whether the diapausing pupa transplanted the brain which was obtained from the pupa recorded the electrical activity developed further or not. Therefore, it seems to be probable from these results that the activation of the secretion of the pupal brain is induced by the nerve impulses. | |||||||
