This book was released on 1967 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The boles of 71 mature ponderosa pine trees killed by Dendroctonus brevicomis LeConte (Coleoptera: Scolytidae) were analyzed to determine the distribution of the attacks by endemic populations of this bark beetle and those of several phloem -feeding associates. The longitudinal -circumferential distribution of the attacks fitted dia- grammatically into four distinguishable bole infestation patterns. The characteristics of the patterns and similarities with comparable ?attacks of D. brevicomis in northeastern California are discussed.

Book Synopsis Biology and Control of the Western Pine Beetle by : John Martin Miller
Download or read book Biology and Control of the Western Pine Beetle written by John Martin Miller and published by . This book was released on 1960 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication reviews the results of research on the western pine beetle up to July 1, 1952. It shows the progress that has been made in over a half-century of study of this one bark beetle. It also records the trials and errors--the research that ran into blind alleys. The record of this pioneer effort in the field of forest entomology in the United States should be of great help to research workers who are faced with similar problems.

Book Synopsis Using Indicator Plants to Assess Susceptibility of California Red Fir and White Fir to the Fir Engraver Beetle by : George T. Ferrell
Download or read book Using Indicator Plants to Assess Susceptibility of California Red Fir and White Fir to the Fir Engraver Beetle written by George T. Ferrell and published by . This book was released on 1986 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using a Vegetation Drought Index (VDI) for estimating the susceptibility of California red and white firs to the fir engraver beetle (Scolytus ventralis) was evaluated in northern California forests where these true firs (Abies species) occur in mixed conifer and true fir stands. Midway through the summer drought, true fir moisture stress-a known predisposing factor-was highest on sites with highest VDI values (most xeric). In mixed conifer stands, the susceptibility of white firs-as indicated by the mean percentage of their basal area killed annually-was highest on sites with highest VDI values. But in true fir stands, the susceptibility of mixed red and white firs was highest on sites with the lowest VDI values. Regression models with VDI, stand basal area, and percentage of true fir as regressors lacked the required predictive range and precision, suggesting that VDI will likely have to be used in combination with predictors other than, or in addition to, those analyzed.
