Western pine-shoot borer by Robert E. Stevens Download PDF EPUB FB2
Abstract: The western pine shoot borer, Eucosma sonomana Kearfott, is a pest of ponderosa pine, Pinus ponderosa Dougl. ex Laws., and can infest other pines in the western USA, by mining the pith of terminal shoots.
This feeding causes an average 25% growth. Western pine-shoot borer: a threat to intensive management of ponderosa pine in the Rocky Mountain area and southwest.
[Robert E Stevens; Daniel T Jennings; Rocky Mountain Forest and Range Experiment Station (Fort Collins, Colo.); United States. The objective of this project is to minimize the influence, to the extent possible, of the western pine shoot borer in these plantations so the trees' actual growth capabilities can be assessed.
This was an operational suppression program aimed at reducing impacts. Thus, no attempt was made to select plantations with similar infestation levels. No other pest produces the shortened, compacted appearance of affected terminals, without killing, as does the western pine shoot borer.
Lateral shoots also may be killed by Diplodia, comandra, or other canker diseases. Look for evidence of shoot borer mining in the pith. References.

The western pine shoot borer is a moth larva feeding in the pith tissue of new terminal or lateral shoots (Figure 1). The reddening and wilting of annual shoots in the upper part of the tree are symptoms of attack by eastern pine shoot borers.
The larvae tunnel into the terminal leader or lateral shoots. The damaged current-year shoots tend to be more easily broken off by the wind. Severe attacks of the insect do not cause tree mortality.
