Download or read book A Case Study of a Douglas-fir Tussock Moth Outbreak and Stand Conditions 10 Years Later written by Boyd E. Wickman and published by . This book was released on 1978 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree damage occurring immediately after an outbreak of Douglas-fir tussock moth, Orgyia Pseudotsugata McD., and stand conditions 10 years later are described. Because of increased radial growth and ingrowth in the 10-year postoutbreak period, good evidence indicates that tree damage caused by the tussock moth may not be as severe in the overall stand dynamics as previously pictured. The insect probably plays a key role as a phytophagous regulator of primary production in some second-growth white fir stands in California and elsewhere.

Download or read book Growth of White Firs Defoliated by Modoc Budworm in Northeastern California written by George T. Ferrell and published by . This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Open-grown, pole-sized white firs defoliated by Modoc budworm (Choristoneura viridis) in northeastern California in the years 1959-62 and 1973-75 suffered only minor growth reductions and topkilling compared with the effects that more protracted budworm outbreaks have had elsewhere on their conifer hosts. Growth index analysis indicated that the firs averaged a cumulative height growth deficit of 14.5 percent, or 34 cm (1.1 ft), over both outbreaks. Firs heavily defoliated during the 1973-75 outbreak were more frequently topkilled and consequently suffered larger height growth deficits. Topkilling during both outbreaks, however, was limited to the terminal shoot, resulting in slight crooks or forks, but no decay, in the stems. Radial growth deficits attributable to the outbreaks were not found and, unless future outbreaks are more protracted or otherwise intensify, the Modoc budworm can be considered only a marginal economic pest of firs in California.
