Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Fir Engraver Beetle: A Serious Enemy of White Fir and Red Fir Attacks are made along the main trunk, usually in roughened bark surrounding the bases of branches. When a suitable spot has been selected for an entrance hole, the female rotates about it and cuts bits of bark away. Within from 36 to 48 hours the hole is ex tended at an upward slant to the cambium layer. The surfaces of the sapwood and inner bark are then deeply grooved to form a nuptial chamber large enough to accommodate two beetles.

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.
