Book excerpt: Infestations of the western pine shoot borer (Eucosma sonomana Kearfott) in young stands of ponderosa pine (Pinusponderosa Lawson), were surveyed on the Deschutes National Forest. Elevation, slope, aspect, tree height, tree diameter, number of shoots in the terminal whorl, stand density, stand age and plant association for each stand were used in general multiple regression and logistic regression analyses to predict the percentage of infested terminal shoots. Using general multiple regression, taking the arcsin(square root(proportion of infested trees)), the models that were selected as the best predictors included (1) diameter, trees/hectare and elevation (R2= 0.62) and (2) number of shoots in the terminal whorl and stand age (R2= 0.62). Using logistic regression, the best model included number of shoots in the terminal whorl and stand age. Values for these stand characteristics can be used with the appropriate equation to estimate the percentage of terminal whorls damaged by shoot borer in a given stand. A companion study performed in six progeny test sites on the Ochoco National Forest found significant differences in shoot borer infestations among 29 ponderosa pine families (P-value = 0.001, R2=O.62).
