The respiratory metabolism of the developmental stages of the Colorado beetle was investigated at varying temperatures and at 20°C. The highest oxygen consumption rate, in mm3 per one individual per an hour was recorded for L4 on its last feeding-day and the lowest for the pupa in the middle of its development. Larval oxygen consumption rate per unit body weight decreases with the increase in body weight of the individuals. Respiratory energy losses by one developing individual at a constant temperature were calculated. The variations in respiration rate at varying temperatures are similar to those at constant tetnperature.
