Abstract
Summary Like the majority of temperate insects, the adult reproductive diapause of the polyvoltine species of the leek moth, Acrolepiopsis assectella (strain of Tours) depends upon both of the photoperiods and temperatures used. A high percentage of diapause is associated with short photofractions and low temperatures. The critical photofraction at 15 °C is about 15 hours per day. The sensitive stage may be the larval one. However, this sensitivity is independant of sex. When the development was performed by the utilization of increasing or decreasing photoperiods (below the critical one), the number of diapausing individuals was higher in the former condition. In this case, it seems that this phenomenon is a sex-dependant. However, it would be difficult to know if this is due to the direction of changing in the photoperiod or to the sensitivity of the last larval stages.
