In order to clarify factors responsible for seasonal prevalence of the rice stem borer, Chilo suppressalis WALKER, effects of photoperiod and temperature on diapause induction have been studied under laboratory conditions. Diapause was induced under a short-day photoperiod (13L:11D), and prevented under a long-day photoperiod (16L:8D) in the larval stage. The photoperiod and temperature in the egg stage seemed to exert no influence upon diapause induction. However, diapause induction was clearly dependent on the photoperiod in the larval stage. The borer larvae were highly sensitive to photoperiod except in the late stage and it was learnt that diapause induction could be reversed by an antagonistic photoperiod. The critical photoperiod for the diapause induction was found to be about 15.0hrs of light per 24hrs at a temperature of 25°C in the Omagari population. However, under conditions of gradually decreasing photophase, the critical light period at the time of hatching was slightly longer than this. Temperature influenced the diapause induction. A low temperature tended to promote the diapause induction.
