Shiny black, bark-eating spruce beetles that kill trees are spreading northward through Colorado’s compromised forests, infesting another , acres this past year — worsening damage. Ips typographus the European spruce bark beetle has caused many problems in Europe and Asia. It is a pest that mostly infects damaged spruce trees, but can also damage healthy trees as well. The effects of this pest have caused a great deal of economic loss as well as ecosystem change.
The spruce beetle usually has a 2-year life cycle in Alberta. Adults Stout dark brown adults (about mm long) overwinter in the tree, then emerge and attack new hosts from late May through June. The female beetle tunnels egg galleries along the wood grain in logs, stumps or standing trees. The female beetle mates with a male in the. Apparently, the pine beetle has a one year life cycle as opposed to the spruce beetle which has a two year cycle. The beetles fly sometime in the late spring, find a tree or trees (they look for larger ones), lay their eggs, and the larvae overwinter and feed on the tree.
The spruce bark beetle (Dendroctonus rufipennis) outbreak in southcentral Alaska has affected 2 to 3 million acres in the past 10 years. In heavily affected stands, often all spruce trees greater than 10 cm are killed. The area affected by tree death is one of the largest ever documented from an insect outbreak in North America (Werner ). Mountain pine, spruce, piñon ips, and other kinds of bark beetles have chomped 46 million of the country’s million acres of forested land, from the Yukon down the spine of the Rocky Author: Maddie Oatman.

However, the effects of canopy reduction by bark beetles and/or salvage logging on wildlife are poorly documented. Spruce beetles primarily attack white spruce by boring through the bark, feeding, and breeding in the phloem.
Their entry through the bark introduces a bluestain fungus (Ceratocystis) that causes tree mortality. STUDY TITLE: Spruce Beetle Effects on Wildlife AUTHORS: William B. Collins, Deanna Williams, and Todd Trapp PERIOD: 1 July –30 June SUMMARY A total of point counts of breeding birds were conducted in Kenai lowland forests during the season, using the variable circular plot method.

Ott, Christopher J. Fettig, Darrell W. Ross, A. Steven. Munson. The spruce beetle,Dendroctonus rufipennis (Kirby), is the most significant natural mortality agent of mature spruce.
Outbreaks of this beetle have caused extensive spruce mortality from Alaska to Arizona and have occurred in every forest with substantial spruce stands. Spruce beetle damage results in the loss of to million board feet of spruce saw timber annually. A spruce tree, dead from a spruce bark beetle attack, stands at the side of the Seward Highway a few miles south of Turnagain Pass, Sept.
7, (Marc Lester/ADN archive ) Share on Facebook. A current epidemic of spruce bark beetle (Dendroctonus rufipennis) has killed white spruce (Picea glauca) on more than million acres in Alaska.
Approximatelyacres of new and ongoing infestation is present on the Kenia Peninsula. This scale of infestation has not occurred in more than years, and the level of salvage logging associated with it is unprecedented.
Spruce beetles (Dendroctonus rufipennis) are native bark beetles that infest Engelmann spruce (Picea engelmannii) and occasionally Colorado blue spruce (P. pungens) in high elevation forests in spruce beetle typically completes a generation in one to three years, with a two-year life cycle being the most common in spruce trees growing above 9, feet.
Spruce Beetle in the Rockies J. Schmid and R. Frye Preface This report summarizes the available literature on the spruce beetle, Dendroctonus rufipennis (Kirby) (Coleoptera:Scolytidae), in western North America.
While it is primarily concerned with the beetle in the central and southern Rockies, recent work in Cited by: QUICK GUIDE SERIES FM Spruce Beetle An Agent of Subalpine Change The spruce beetle is a native species in Colorado’s spruce forest ecosystem.
Endemic populations are always present, and epidemics are a natural part of the changing forest. There usually are long intervals between such events as insect and diseaseFile Size: KB. Dendroctonus rufipennis, the spruce beetle, is a species of bark beetle native to British Columbia, Newfoundland and Labrador, Nova Scotia, Ontario, Quebec, Northern Manitoba, the Yukon, Colorado, Wyoming, Montana, and are known to destroy forests of spruce trees including Engelmann, White, Sitka, and Colorado blue spruce.
Adults average 4 to 7 mm in : Curculionidae. Effects: The direct effect of spruce beetle attack is tree mortality or in some cases strip kill, when only a vertical section of the bole is attacked.
Strip attacked trees often die in subsequent years. Spruce beetle epidemics can have both immediate and long-term effects on spruce-fir forests. Spruce Beetle Infestation Control. A spruce beetle infestation is damaging to your spruce trees. It is deadly to the trees in the majority of cases, as the feeding galleries the beetles create prevent the trees from gaining nutrition.
You will need the help of a professional tree surgeon to help with spruce beetle control and management. The spruce bark beetles have developed not just a resistance to terpenes, but in some cases terpenes are an attractant to the spruce bark beetle. The spruce bark beetle has developed a means of sensing some of the terpenes and using it as a homing beacon to find trees that are under attack or under stress.

1– Page [>]. A bark beetle is one of about 6, species in genera of beetles in the subfamily Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be specialized clade of the "true weevil" family (Curculionidae).Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many Class: Insecta.
The most damaging bark beetle species attacking Minnesota's pines are native engraver beetles (Ips species), also known as pine bark (Norway) and jack pine are the most common victims of pine bark beetles, although white pine and spruce can also be infested. Finally, Engelmann spruce in this region of Colorado has undergone extensive mortality as a result of spruce beetle in recent years (Andrus et al., ; Harris, ;Hart et al., ) which may.
Stand and landscape level effects of a major outbreak of spruce beetles on forest vegetation in the Copper River Basin, Alaska Article in Forest Ecology and Management (3) June The brown spruce longhorn beetle (Tetropium fuscum) is native to northern and central Europe, Russia and Canada, it infests spruce trees, such as red, white, black and Norway.
Except for a small population near Calhoun, New Brunswick, the brown spruce longhorn beetle has only been found in Nova Scotia. Consequently, young (Cited by: 6. Spruce beetle outbreaks have been reported in the Rocky Mountains of western North America since the late s. In their classic paper, Spruce Beetle in the Rockies, Schmid and Frye reviewed the literature that emerged from the extensive outbreaks in Colorado in the s.
A new wave of outbreaks has affected Rocky Mountain subalpine spruce-fir forests beginning in the mids and Cited by: The spruce beetle, Dendroctonus rufipennis, is the most destructive pest of mature spruce trees in British Columbia. Outbreaks usually last years, and these may severely deplete the large-diameter spruce (Picea spp.) component of forest stands.Spruce beetle effects on wildlife William Brian Collins Not In Library.
