Abstract
Site preparation prior to planting slash pines significantly influenced subsequent attacks by the pine webworm, Tetralopha robustella Zeller, at the end of the slash pines' 2nd growing season (in one of 3 studies). Numbers of trees infested followed a site preparation intensity gradient with the most trees being attacked on the burn-harrow plots and the fewest trees being attacked on the burn-harrow-high bed plots. In all three studies, tip moth ( Rhyacionia spp.) infestation followed a site preparation intensity gradient with significantly more pines attacked on the most intensively prepared plots. This attack pattern occurred by the end of the pines' 2nd growing season.
