Rhythm of Oxygen Uptake in Diapausing Larvae of the Codling Moth at Several Temperatures1

Abstract
The oxygen uptake of larvae of the codling moth, Laspeyresia pomonella (L.) (Lepidoptera: Olethreutidae), in diapause, decreased from an average of 0.2 to loss than 0.05 microliters/milligram wet weight per hour at 26.6 and 11°C, respectively. At 20 and 23°C, a circadian rhythm of consumption was observed, but none was apparent at 11, 14, 17, or 26.6° C. About an 8-hour rhythm was determined for insects kept at 26.6°C, but this rhythm could not be validated statistically at the other test temperatures.
