oa Journal of the Entomological Society of Southern Africa - Synthesis of fat in locusts

Volume 9, Issue 1
  • ISSN : 0013-8789



Some sixth stage hoppers of the Red Locust, Nomadacris septemfasciata Serville, were fed on the leaves of Oxalis purpurascens, and were used as subjects for respiration experiments in the micro-Haldane apparatus. Their respiratory quotient was invariably 1.3. This indicates that more oxygen is being liberated than would be required to metabolise the food, and thus it appears that fat metabolism may be very active. It was decided to carry out a special balance experiment with one animal while others were killed for the purpose of extracting and analysing their fat.
