Triglyceride metabolism inEphestia cautella pupae exposed to carbon dioxide

  • Published:
Experientia Aims and scope Submit manuscript


The triglyceride content ofEphestia cautella pupae exposed to increased carbon dioxide atmospheres at low relative humidity was not markedly affected. There was a significant increase in weight loss of pupae exposed to low relative humidity. Results indicate that forE. cautella, metabolic water formation by fat utilization can hardly regulate water exigencies for the pupae and cannot fully compensate for water losses in high carbon dioxide atmospheres.
