Mark record


The life-span of Swaine jack-pine sawfly adults was studied under various constant and alternating temperatures and at four different values of relative humidity. Temperature significantly influenced the life-span of both sexes according to a non-linear equation, and relative humidity according to a linear regression. The influence of temperature varied with relative humidity in the case of males but not in the case of females. The life-span of both sexes was shorter at alternating temperatures than at constant temperatures.
