Abstract
AbstractLaboratory experiments were conducted to determine the effects of bark moisture content on the survival and development of Polygraphus rufipennis (Kirby). Adults and immature stages were reared in white spruce bark of five different moisture contents for 20, 40, and 60 days. Adult activity and brood success were related to the moisture content of the bark with the adverse effects of the drier bark becoming more pronounced with time. After 40 days factors associated with high bark moisture levels, such as fungus and rate of decomposition, may have been responsible for a decrease in survival and rate of development in the moister bark.
