Accuracy of determining mountain Pine beetle attacks in Ponderosa Pine utilizing pitch tubes, frass and entrance holes


, : Accuracy of determining mountain Pine beetle attacks in Ponderosa Pine utilizing pitch tubes, frass and entrance holes. USDA Forest Service Research Note, Rocky Mountain Forest and Range Experiment Station (RM-222): 2

In a study in Colorado in 1971, counts of external indicators of attack by Dendroctonus ponderosae, throughout the infested length of five sampled stems of Pinus ponderosa on two sites, agreed closely with the actual number of attacks (counted after barking).
