Larval development and gonad maturation of a carabid beetle, Carabus yaconinus BATES were studied at six different temperature and photoperiod conditions, i.e., 25℃, 16L-8D; 20℃, 16L-8D; 20℃, 14L-10D; 20℃, 12L-12D; 15℃, 16L-8D; 15℃, 13L-11D. The length of developmental period in immature stages was influenced by temperature but not by photoperiod. Ovarian maturation took place under 16L-8D but was suppressed by both short-day conditions and high temperatures. Fat bodies developed when ovarian maturation was suppressed. The testes matured under all the experimental conditions but fat bodies developed only under short-day conditions at lower temperatures. The suppression of ovarian maturation and development of fat bodies indicated that the adults were in reproductive diapause. These diapause responses were related to the control of the univoltine life cycle of this species.
