Abstract
The European pine shoot moth, Rhyacionia buoliana (Schiff.), has been recognized as a pest of pine plantations since it was described in 1776. Neugebauer (1952) stated that 32 susceptible pine species were known and that scarcely any species were rejected by the insect. Following its accidental introduction into North America about 50 years ago (Busck, 1914) the shoot moth became a serious pest of red pine, Pinus resinosa Ait., which appears to be the most susceptible species (Heikkenen and Miller, 1959). Watson (1947) described the shoot moth as “the most destructive insect affecting hard pines in southern Ontario, and the most difficult to control”. Plantations have been damaged so severely that the planting of red pine has been virtually discontinued within the pest's range.
