Abstract

Different categories of logging residuals were evaluated from the standpoint of attack density and brood production. The bottom surfaces of cull logs and tops generally had higher attack and brood densities than the upper surfaces. Stumps had considerable variation in attacks and brood between the north and south side. General guidelines for minimizing beetle production from logging residuals are developed form the results.
