    Description

    Studies to evaluate the impact of insects on the establishment of advance oak regeneration in Pennsylvania were initiated in 1989. The populations and species of insects feeding on germinating acorns and new seedlings, their activity periods, and the damage caused by these insects were studied in relation to overstory-density (40, 60, and 100 percent relative density) and understory vegetation control (herbicided and unherbicided) at three sites in the unglaciated Allegheny Pleteau in Clearfield County.
