• The mechanism of photoperiodic response in Leptinotarsa decemlineata has been regarded as a model for adult diapause. Recently, the evidence of regulatory mechanisms for adult diapause has been accumulated and the outline of adult diapause was clarified in Riptortus clavatus, an alternating model. This review summarizes the neural and endocrine mechanisms of the photoperiodic response controlling adult diapause in R. clavatus. R. clavatus has facultative diapause in adult stage. Photoperiodic regulation of diapause is a long-day type. The photoperiodic receptor is localized in the central region of the compound eyes. The endocrine effector organ responsible for reproductive diapause is the corpus allatum. In diapause adults, the brain suppresses the corpus allatum activity via the nerve. Consequently, a reduced juvenile hormone titer in the hemolymph causes suppression of reproduction. However, cuticular mechanical properties and lipid accumulation associated with diapause do not depend on the corpus allatum activity.
