以下内容实际上是作者的摘要。节节肉蛾和黑腹蝇糖原含量的测定证实了E。Bursellin 1958提出，虽然前者含有相当数量的碳水化合物，但在后者中只能检测到微量的碳水化合物。测定了两种昆虫飞行肌肉匀浆上清液中碳水化合物分解相关酶的活性。在海藻酶、磷酸化酶、磷酸葡萄糖变位酶、葡萄糖磷酸异构酶、磷酸果糖激酶和Aidolase的情况下，Glossina中的Sarcophagathan的活性要高得多。在肉食性肌肉的线粒体中检测到大量的海藻糖酶活性，而在舌状肌中没有检测到海藻糖酶活性。在这两种昆虫中均未检测到葡萄糖-6-磷酸酶或果糖-1，6-二磷酸酶。这两种昆虫线粒体中的琥珀酸脱氢酶活性相似。上述发现与假设是一致的，即飞行所需的能量来自不同于其他大多数双翅目的代谢产物。
The following is virtually the authors' abstract. Estimations of the glycogen content ofSarcophaga nodosaEngel andGlossina morsitansWestw. confirmed earlier observations ofE. Bursellin 1958 that only minute amounts of carbohydrates could be detected in the latter, although considerable amounts are present in the former. The activities of enzymes involved in carbohydrate breakdown in the supernatant fraction of homogenates of flight muscle of both insects were determined. In the case of trehalase, phosphorylase, phosphoglucomutase, glucosephosphate isomerase, phosphofructokinase and aidolase, activities were found to be considerably greater inSarcophagathan inGlossina. Considerable trehalase activity was detected in the mitochondriaI fraction ofSarcophagaflight muscle, but none was detected in the case ofGlossina. No glucose-6-phosphatase or fructose-1, 6-diphosphatase could be detected in either insect. Succinic dehydrogenase activity in the mitochondria was found to be similar in the two insects. The findings outlined above are consistent with the hypothesis that the energy required for flight inGlossinais derived from different metabolites than in the case of most other Diptera.
