Abstract: All stages of a strain of Tribolium castaneum (Herbst) selected for resistance in the adult stage to a high carbon-dioxide-content atmosphere and of an unselected strain were exposed to the high carbon-dioxide-content atmosphere. Similarly, all stages of a strain selected for resistance to a low-oxygen-content-atmosphere in the adult stage, and all stages from an unselected strain, were exposed to the low-oxygen-content atmosphere. For both selected strains, partial resistance was displayed by the eggs and larvae.

Key Words: Insect. Tribolium castaneum, controlled atmospheres, resistance
