Western Hemlock Looper Biology & History The western hemlock looper is periodically destructive in coastal and interior forests, reaching outbreak proportions every 11 and plus years, respectively.

Outbreaks usually last about three years, after which they are generally brought under control by the action of parasites, predators, and diseases. Other information. The western hemlock looper is one of the most destructive forest defoliators in British Columbia. Major outbreaks have occurred on the coast (on Vancouver Island and adjacent south coast in ) and in the interior wetbelt (upper Fraser River; North Thompson-Wells Gray Park and ; Arrow Lakes ; Shuswap Lake 1971 book Horsefly Lake.

Western Hemlock Looper The western hemlock looper is a native defoliator of western hemlock, western redcedar, interior spruce and Douglas-fir. This insect periodically reaches outbreak levels, causing severe damage to forests in both Interior and coastal stands in British Columbia.

Hemlock looper outbreaks develop and subside very suddenly. They spread quickly and can cause the death of balsam firs in the first year that damage is detected.

The wasteful feeding of this species and its rapid population growth make it a serious defoliator. There are four or five larval stages, depending on the region of Canada.

The last outbreak was from near Baker Lake, the City of Everett Watershed surrounding Lake Chaplain, and near Arlington. There also are indications that hemlock looper populations are rising in north Idaho and possibly northeastern Washington.

Western hemlock stands provide cover and habitat for many wildlife species and small mammals. It is also used for nest trees by cavity nesting birds. This species is browsed by elk and deer.

The seedlings are eaten by snowshoe hares and rabbits. Agroforestry: Western hemlock is used in forested. The culprit is the Hemlock Looper.

They feed voraciously and defoliate the upper crown; by the time you notice the dieback it's too late. Apparently, you can have Bacillus Thuringiensis vr. kustaki (a microbial insecticide, specific to the looper larvae) sprayed on your Hemlocks during the first year, and this will help protect the tree.

Missoula, MT.: Forest Environmental Protection, USDA, Forest Service, Northern Region, State & Private Forestry, The Eastern and the Western Hemlock Looper are closely related and are now recognized as a single native species by many scientists.

The Eastern Hemlock Looper prefers fir as a host tree but it is also a defoliator of Spruce, Larch and occasionally deciduous trees like Maple, Birch and Poplar while the Western Hemlock Looper attacks Western Hemlock, Red Cedar, Spruce and Douglas-fir.

Pilot test results of Sevin, Phosphamidon, and DDT on the western hemlock looper: Lambdina fiscellaria lugubrosa Hulst, in southwest Washington in View Metadata By: Buffam, Paul E. Growth: Western Hemlock typically grows feet (m). The tallest Western Hemlock is over feet (73m) tall.

The oldest are over years old. Habitat: Seedlings of Western Hemlock often begin life on the decaying wood of “nurse logs.” or stumps in the shade of Douglas Firs. They usually start out growing slowly in the shade, much faster in full sunlight when an event occurs.

My dissertation examines western hemlock looper (Lambdina fiscellaria lugubrosa Hulst) as an agent of disturbance in coastal forests of British Columbia.

Western hemlock looper populations along coastal British Columbia have undergone seven episodes of outbreak from toleading to visible defoliation of western hemlock (Tsuga heterophylla (Raf) Sarg.)-dominated forests.

My research. supply of western hemlock wood. A rapidly increasing proportion of the lumber manufactured in the United States is cut from western hemlock. In the species ranked twenty-fifth in lumber production, furnishing only per cent of the total output. Inas shown by Figure 2, the cut of western hemlock began to increase rapidly.

during the adult and larval periods.$ The western hemlock looper, Lambdina fisceZZaria Zugubrosa (Hulst.), found only in the southern part of southeast Alaska, occurs primarily south of 56 degrees latitude in British Columbia (Jardine ).

The western hemlock looper (Lambdina fiscellaria lugubrosa Hulst) is a defoliating Lepidoptera native to western North America that has significant impacts on timber management and forest ecology (Parfett et al. Western hemlock looper's distribution corresponds with the range of its preferred host, western hemlock (Tsuga heterophylla [Raf.

Outbreaks of Lambdina fiscellaria lugubrosa in British Columbia have always been preceded by a rapid population growth. Sampling methods and population prediction models are needed to provide forest managers with the capability of monitoring and predicting populations of the insect.

I sampled eggs, larvae, pupae and adults of Lambdina fiscellaria lugubrosa at various locations in the province. Abstract: Western hemlock looper, Lambdina fiscellaria lugubrosa (Hulst), is an important defoliator of western hemlock, Tsuga heterophylla (Raf.) Sarg., and other conifers in the United States and Canada.

Periodical damage generally occurs in mature or senescing stands, where defoliation results in growth reduction, top kill.
