Mature larvae of A.luxuriosa entered diapause under both long (14L : 10D) and short (8L : 16D) photoperiods. When the photoperiod was changed from a short day to a long day on certain days between the 5th and the 55th day after egg-hatching, diapause was not induced and adult emergence took place remarkably earlier than in the case of constant photoperiod. The period from egg-hatch-ing to adult emergence was shortest when the photoperiod was changed on the 10th or the 30thday after egg-hatching. When the photoperiod was changed on the 55th day, the rate of emergence was highest and emergence took place practically at the same time. When the photoperiod was changed from long day to short day on the 40th day after egg-hatching, the duration of the diapause was longer than under constant photoperiod and most of the larvae did not pupate until the 350th day after egg-hatching. The change in day length and its trend were considered to be more effective in the induction of diapause than the photoperiod itself.
