    The Douglas-fir tussock moth is a native insect in the low-lying, dry belt Douglas-fir regions of southern British Columbia. This insect is both a private land and public forest issue. Outbreaks of tussock moth occur every years and cause significant damage and mortality to Douglas-fir stands in these areas. If the tops of your Douglas-fir trees are looking a little bare and brown, there’s a possibility the Douglas-fir tussock moth has moved into your neighborhood. The caterpillars can come in and destroy parts of a forest in what residents claim to feel like just a day or so.

Defoliation by the tussock moth. Tussock Moth caterpillars (from the family Lymantriidae) are voracious eaters capable of defoliating entire forests.

The best-known member of this family is the beautiful but highly detrimental Gypsy Moth which is not native to North America. After its introduction, the potential for destruction these critters could wreak became all too clear.

The sex pheromone of the Douglass-fir tussock moth Orgyia pseudotsugata (McDunnough) has been isolated and identified as (Z)heneicosenone. This compound and its E isomer have been synthesized and are highly potent in laboratory bioassays and field trials. Douglas-fir Tussock Moth Orgyia pseudotsugata Key Wildlife Value: The Douglas-fir tussock moth creates snags and down wood by severely defoliating and causing the death of all sizes of true fir and Douglas-fir trees.

It also interacts with other disturbance agents, especially bark beetles, to. 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 regularity.

Fluctuations in density on warm, dry sites where populations have a high intrinsic rate of increase are more likely to periodically reach outbreak. Service during the Burns Tussock Moth Control Project (2, 3).

In early fallas soon as it became evident that aerial insecticide applications might be necessary to control the insect outbreak, meetings were organized to plan monitoring programs.

All interested persons, organizations, and agencies were notified of the proposed control. The Forest Entomologist with the Thompson Okanagan Region, Ministry of Forests, Lands and Natural Resource Operations (MFLNRO) states we are experiencing the start of a Douglas-fir tussock moth outbreak throughout the region.

She checked out our area a week ago and found evidence of the natural virus in the population. If private land owners want.

The Boise National Forest is experiencing another outbreak of Douglas-fir Tussock moths/caterpillars, which damage trees and can be harmful to some individuals. The U. Forest Service wants to remind forest visitors not to touch or pick them up.

The moth’s tree-damaging caterpillar has long bristly hairs that may cause allergic-like reactions for some individuals. Douglas-fir Tussock moth virus (TM Biocontrol-1) Wild populations of the Douglas-fir tussock moth have several naturally-occurring diseases that cause mortality to certain life stages of the insect during the course of an outbreak.

The agentsnucleopolyhedrosis virus (NPV) that cause these diseases are bacteria, fungi, and viruses, among others.
