Central mechanism controlling photoperiodism and diapause in stink bugs.

在Riptortus pestris中，由周期、周期、哺乳动物型隐色素和时钟组成的生物钟是光周期不可缺少的。此外，视叶中的色素分散因子免疫反应神经元可能参与光周期变化。在闭目鱼中，包括脑间部和侧部在内的脑区通过抑制幼体激素的生物合成来调节滞育，并建立了检测幼体激素分子的方法。

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.
