自 1935 年以来，人们一直在研究不同基因型黑腹果蝇在蛹期最初几个小时内的呼吸作用。这项工作现已完成，完整的说明很快就会准备好发表。然而，目前可以说每毫克摄氧量存在差异。最初在两性之间以及野生型和其突变残留体之间发现的体重后来被证明是由于这些动物的体型略有差异所致；当通过改变培养条件消除这些差异时，代谢差异也消失了。通过实际测量蛹的表面积，进一步表明每mgm的表面积。随着身体尺寸的增加，每毫克氧气消耗量的下降速度与每毫克氧气消耗量相同，因此氧气消耗量与表面积有关。
SINCE 1935, work has been proceeding on the respiration of different genotypes of Drosophila melanogaster during the first hours of the puparial period. The work has now been completed, and a full account will shortly be ready for publication, For the moment, however, it may be said that differences in oxygen uptake per mgm. body weight originally found between the sexes and between the wild-type and its mutant vestigial were later shown to be due to slight differences in the sizes of these animals ; when these were eliminated by alteration of the culture conditions the metabolic differences also disappeared. By actual measurement of the surface area of puparia it was further shown that the surface area per mgm. decreased, with increasing body size, at the same rate as did the oxygen consumption per mgm., and that the oxygen consumption was therefore related to the surface area.
