Zusammenfassung:This study was carried out to investigate the effects of photoperiod and temperature on induction and termination of reproductive diapause in the black rice bug, Scotinophara lurida (Burmeister). Newly ecdysed fourth-instar nymphs and emerged adults of S. lurida adults did not enter reproductive diapause when reared at 30 °C in any photoperiod used. However, they exhibited the threshold photoperiod between 9 and 10 h at 25 °C and between 12 and 16 h at 20 °C  adults overwinter in a state of reproductive diapause induced by short photoperiod and/or low temperature.
