At a constant temperature of 20°C bugs reared under short-day photoperiod (SD) (12L-12D) regime from the first instar nymphs entered the diapause and exhibited the coloration change from green to brown in the adult stage. Transfer of adults from long-day photoperiod (LD) (15L-9D) to SD regime suppressed oviposition and induced the brownish coloration. After transfer from SD to LD regime adults started laying eggs and their coloration became green. In addition, the females which received for a longer period under SD regime tended to oviposit earlier after transfer. These results indicate that P. stali is sensitive to photoperiod even after adult emergence and that the diapause development proceeds under SD regime without the exposure to a low temperature.
