SUMMARY
| 1. | Diseased pupae of P. cecropia undergo a 20-fold increase in oxygen uptake as a result of parasitism by A. flavus; a substantial part of this increase is due to the metabolism of the host alone. | ||||
| 2. | Weight loss of diseased pupae roughly parallels the respiratory increase and is due mostly to evaporation of water from the spiracles. | ||||
| 3. | The rate of weight loss is directly proportional to the temperature up to 28° C. | ||||
