✦ Synopsis
The occurrence in the literature of a large number of papers dealing with the respiratory metabolism of insect pupae attests to the general interest attached to the subject of insect metamorphosis. The results of many investigations, including those of Bataillon (1893), Luciani and Lo Monaco (1893), Weinland ( '06), Tang1 ( '09), Bodine and Orr ( 'ZFi), Clare ( '25), Fink ( '25), Taylor ( '27)' Frew ( '29), Ludwig ( '30), and Taylor and Steinbach ( '31)' have demonstrated that the rate of oxygen consumption or of carbon dioxide production is not constant throughout pupal life but varies in a definite manner. The rate of gaseous exchange, relatively high immediately after pupation, decreases as metamorphosis progresses until a minimum is reached, and then rises. Judging from the investigations of Krogh ('14) and of Janda and KociAn ( '33) on the meal worm (Tenebrio molitor), such characteristic U-shaped metabolic curves are typical for pupal development at all temperatures which are within physiological limits. The results obtained by Krogh ('14) and by Janda and Kocibn ( '33) indicate that variations in temperature merely influence the velocity of respiratory metabolism and of development; the higher the temperature, within certain limits, the greater is the intensity of gaseous exchange and the shorter is the duration of pupal life. Krogh also concludes that the total amount of carbon dioxide produced 351
