Triglyceride metabolism in Ephestia cautella pupae exposed to carbon dioxide

The triglyceride content of Ephestia 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 for E. 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.
