Abstract:
The effects on mortality and loss in weight caused by 21, 51 and 88% carbon dioxide in combination with relative humidities of 20-22, 54-55, and 95-96% were tested on 0-24 hr old Ephestia cautella pupae, at 26°C. Exposure times ranged from 1 to 6 days. At 54-55%, and 20-22% r.h. pupal mortality was high for all carbon dioxide concentrations used, while at 95% r.h. total mortality was obtained only at the highest carbon dioxide concentration tested. At carbon dioxide concentrations of 51 and 88% a 9-11% concentration of oxygen was present. At 20-22% and 54-55% r.h. loss in weight of pupae exposed to carbon dioxide concentrations of 21% and higher was very pronounced. At 95-96% r.h., none of the treatments resulted in loss in weight exceeding 16% after six days of exposure. A 95% mortality curve represents the interrelated effect of carbon dioxide and relative humidity on the moth pupae. The fumigant effect of carbon dioxide is discussed. © 1974.
