英文摘要	The yellow peach moth, Conogethes punctiferalis (Guenee), a multivoltine species that overwinters as diapausing larvae, is one of the most serious insect pests on maize in China. Effect of photoperiod and temperature on larval diapause was examined under empirical laboratory conditions. Short-day treatments caused larval diapause at 25 degrees C, and the critical photoperiod was between 12 and 13 h (or 12 h 51 min) light per day. No sensitive instar was identified for diapause induction under alternated short- (L : D 11: 13 h) and long-day (L : D 14: 10 h) treatments at different larval stages. However, accumulative treatment of three instars and 10 d under short-day treatment was required for the induction of 50% larval diapause. All larvae entered diapause at 20 degrees C, whereas less than 3% did so at 30 degrees C, irrespective of the long- or short-day treatment. Furthermore, under the short-day treatment, more than 90% of larvae went into diapause with temperatures <= 25 degrees C, but less than 17% did so at 28 degrees C. In contrast, under the long-day treatment, less than 19% of larvae went into diapause with temperatures >= 23 degrees C. The forward shift (5 degrees C) of critical temperature under the long-day regime demonstrated the compensatory effect of temperature and photoperiod on diapause induction. In conclusion, C. punctiferalis had a temperature-dependent type I photoperiodic diapause response; there was no sensitive instar for diapause determination, but the photoperiodic accumulation time countermeasures both of the short-day cycles and the number of instars exposed, and the photoperiodic diapause response, was a temperature-compensated phenomenon.
