Abstract

Comparative studies on breeding and survival of Polygraphus rufipennis (Kirby) in black spruce, Picea mariana (Mill.) BSP., red spruce, P. rubens Sarg, and white spruce, P. glauca (Moench) Voss, indicate that red spruce is the most favourable host. The thicker, more scaly bark of red spruce and the less frequent occurrence of competition for bark space and food by other organisms are considered as contributory to the success of beetles in this host tree.
