Abstract
The pales weevil (Hy-lobius pales) sometimes causes serious losses among young pines in the south. The beetles are attracted to freshly cut stumps and dying pines and they feed on reproduction in the vicinity of such material. In cutting areas in the Duke Forest, 50% mortality of the advanced reproduction of loblolly pine (Pinus taeda) and shortleaf pine (P. echinata) is not uncommon. Similar damage also occurs in the vicinity of pines killed by the southern pine beetle (Dendroc-tonus frontalis) and Ips. In the south there appears to be one complete generation and a partial 2d overlapping generation annually and it breeds only in the roots of dying pines and stumps. Regression analysis demonstrated that the average number of killed pine seedlings varies directly with the number of available seedlings and inversely with the distance from the source of attraction.
