This paper presents information collected to date on the tussock moth (Orgyia pseudotsugata) population in northern Idaho, reviews management options available, and discusses strategies for dealing with this insect on the Clearwater National Forest through future outbreaks. The major tree species affected in this area are Pseudotsuga menziesii, Abies grandis and A. lasiocarpa. + Image Credits.

BOISE Against the backdrop of the worst recorded forest pest epidemic in southern Idaho, the Boise National Forest has discovered yet another insect problem the tussock moth. The Douglas-fir tussock moth is a moth that feeds on fir trees, "They eat the needles on the tree, and they also eat the new buds when it, you know, buds,” said Bob Pietras, with the Idaho.
Abstract: The Douglas-fir tussock moth is a major defoliator of Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, and true firs, Abies spp., in western North America. Defoliation can often be severe and cause tree mortality during the first year of defoliation. The number of O. pseudotsugata adults caught in delta-shaped sticky traps.

Douglas-fir tussock moth populations are monitored annually in northern Idaho and western Montana to insure early detection of changes from endemic to outbreak population levels. Adult moth trapping in was intensified and expanded into additional areas from because of concern that with each passing year the probability of a tussock.
The Douglas-fir tussock moth is native to Idaho, and outbreaks happen on roughly a year cycle. An outbreak usually lasts for about four years, with the third and fourth years being particularly noticeable for defoliation. The outbreaks are cyclical, and they tend to peter out on their own.

DOUGLAS-FIR TUSSOCK MOTH ADULT MALE SURVEY NORTH IDAHO AND WESTERN MONTANA, by J. Dewey -/, R. Livingston 2./, and S. Kohler 2/ INTRODUCTION • Douglas-fir tussock moth 4/ populations are monitored annually in northern Idaho and western Montana to insure early detection of changes • from endemic to outbreak population levels.
The Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), is an important defoliator of spruce, Douglas-fir, true fir and other conifers in the Rocky Mountain region. Feeding by the larvae can cause complete defoliation of heavily infested trees. Damage usually appears first in the tops of trees and progresses downward, sometimes over several years.
Survey plots for monitoring adult male moth populations were located at 33 areas in western Montana, 61 in Idaho north of Moscow, and 64 in Idaho south of Moscow and north of Biggins.
An additional plot was added in Idaho north of Moscow duringand three plots north of Moscow and two south of Moscow were dropped from the survey. The Forest Service reports the Douglas-fir tussock moth “can be one of the most damaging of western defoliators.” The agency says the moth has a.
Idaho land managers set two major timber sales to salvage thousands of dead or dying evergreen trees killed or damaged by a Douglas-fir tussock moth infestation in Packer John State Forest north. The Douglas-fir tussock moth caterpillars recently left several campers in the Sage Hen recreation area with allergic reactions and skin irritation.
Author: Shirah Matsuzawa Published:. The objective of this report is to describe a recent () increase in Douglas fir (Pseudotsuga menziesii) tussock moth (Orgyia pseudotsugata) activity in northern Idaho and Montana, USA.
The report also relates current conditions to historical and future trends and, at a wider scale, increasing tussock moth activity in surrounding western states. BOISE () — A moth infestation in the Packer John State Forest near Smiths Ferry is killing trees and forcing the Idaho Department of Lands to conduct salvage timber Douglas-fir tussock.
The Douglas-fir tussock moth is one of the most destructive forest defoliators in western North America. Densities of most tussock-moth populations fluctuate over time with considerable regular- ity.
Fluctuations in density on warm, dry sites where populations have a high intrinsic rate of increase are more likely to periodically reach outbreak. Idaho and western Montana. Current Tussock Moth Activity Numbers of adult male tussock moths caught in pheromone traps in northern Idaho and western Montana have been increasing since At approximately 95 trapping sites in northern Idaho, ab moths were caught incompared to 6, moths in The Montana S.
Douglas-fir tussock moth (DFTM) population increases were first detected through traps set in cooperation with West-wide DFTM Early Warning Pheromone Detection Survey in By the USDA Forest Service Forest Entomologist in Sonora observed defoliation around Crane Flat.
The Boise National Forest is reporting an outbreak of the Douglas-fir tussock moths in and around Sage Hen Reservoir, a popular recreation area located 5 miles west of Smiths Ferry. Moth insects found in the state of Idaho. There are a total of [ ] Idaho Moths in the database. Consider contributing an image at the email address showcased at the bottom of this page.
The Idaho Department of Lands is dealing with a big problem caused by a small creature. The tussock moth has infested Douglas-fir in the Packer John State Forest.
The outbreak means the trees are more susceptible to wildfires. Now, IDL is planning to cut down some of the infested trees in an effort to contain the problem.
