SURVIVAL OF EUROPEAN PINE SHOOT MOTH, RHYACIONIA BUOLIAINA (LEPIDOPTERA: OLETHREUTIDAE), UNDER CAGED CONDITIONS IN A PONDEROSA PINE FOREST
Published online by Cambridge University Press: 31 May 2012
Abstract
The European pine shoot moth developed successfully on native lodgepole and ponderosa pines at central Oregon locations. Lodgepole and slow-growing ponderosa pine less than 6 ft in height were most susceptible to damage. Largely because of low winter temperatures, interior British Columbia, northern Washington, northeastern Oregon, Idaho, Montana, Wyoming, Nebraska, and the Dakotas are not likely to experience Rhyacionia buoliana (Schiff.) damage. In contrast, southern Oregon and northern California pine stands are highly susceptible.
