| Research Abstract |
In Riptortus pedestris, a circadian clock consisting of period, cycle, mammalian-type cryptochrome, and Clock is indispensable for photoperiodism. Moreover, the pigment-dispersing factor immunoreactive neurons in the optic lobe were suggested to be involved in phototoperiodisim. In Plautia stali, a brain region including the pars intercerebralis and pars lateralis regulates diapause by inhibiting juvenile hormone biosynthesis, and the method for detecting the juvenile hormone molecule was established.
