Healthy lodgepole pine trees (Pinuscontorta Dougl. var. latifolia Engelm.) were girdled on the lower trunk in patterns designed to selectively eliminate the influence of materials transported from the roots, lateral tissues, and crown. Titres of soluble sugars and starch observed in areas isolated by girdling were significantly lower than those observed in areas open to the upper bole and crown. Corresponding decreases were observed in the numbers of Dendroctonusponderosae Hopkins attacking those areas.

New Formulation

Abstract A large-scale field experiment was conducted on the Flathead National Forest, Montana, to evaluate the efficacy of 0.5%, 1.0%, and 2.0% formulations of Sevimol® and Sevin brand XLR® for protecting individual lodgepole pines (Pinus contorta var. latifolia Engelm.) from attack by mountain pine beetles (Dendroctonus ponderosae Hopk.). All concentrations and formulations were highly effective (>95%) in protecting lodgepole pine trees from lethal attack by mountain pine beetle for 1 year, and the 1% and 2% concentrations were effective (>90%) for 2 years.

Variance Estimates

AbstractA method was developed for estimating attack and brood totals of the mountain pine beetle in part or all of the infested bole of individual lodgepole pine trees. The method requires measurement of tree height, tree diameter at 1.37 m, and maximum height of attack, and tallying of brood and attacks on paired 20 cm by 30 cm samples centered at 1.22 m on the bole. Attack and brood totals are estimated in two ways: (1) as a product of the variables (a) total bole surface area, (b) proportion of bole surface area infested, and (c) mean attack/brood density; and (2) regression on the combined variables of tree diameter, infested height, and attack/brood density at 1.22 m on the bole. An approach to developing variance estimates for brood and attack totals is discussed.
