Mountain pine beetle (Dendroctonus ponderosae) (MPB) outbreaks are increasingly prevalent in western North America, causing considerable ecological change in pine (Pinus spp.) forests with important implications for wildlife. We reviewed studies examining wildlife responses to MPB outbreaks and postoutbreak salvage logging to. The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), has an obligatory dispersal phase before selection of a suitable host for brood production. Flight during the dispersal phase is affected by both beetle physiology and environmental : Asha N Wijerathna. Jordan L. Burke, Allan L.

The range of many Holarctic forest insects does not comprise the entire range of their hosts, as they are often limited to more southern latitudes by the adverse effects of cold temperatures.

The effects of mountain pine beetle are greatest in climax lodgepole pine forests where lodgepole pine is self-perpetuating or in even-aged stands where shade-tolerant species are not abundant enough to replace lodgepole pine. These even-aged forests are usually created by a stand-replacement fire. Forest management decisions regarding the mountain pine beetle (Dendroctonus ponderosae Hopk.) are generally driven by the location, size, and impact of the beetle population. ponderosa, limber, and Rocky Mountain bristlecone pines. All of these species of pines are acceptable and suitable host trees for the mountain pine beetle. Examination of the available evidence provides support for the continued spread of mountain pine beetle throughout lodgepole pine forests and into ponderosa pine forests. Mountain pine beetle (MPB) is an insect native to the forests of western North America and is also known as the Black Hills beetle or the Rocky Mountain pine beetle. MPB primarily develop in pines such as lodgepole, ponderosa, Scotch and limber pines, and less commonly affect bristlecone and piñon pines.

Mountain pine beetles, like other bark beetles, are intimately asso-ciated with their ority ofthelife cycle of the beetle, with the exception of a brief dispersal flight period among adults, is spent under the bark and within the tissues of host trees (Wood ). Female mountain pine beetles are the host-selecting sex.   Bark beetles range from Canada to Mexico and can be found at elevations from sea level to 11, feet. The effects of bark beetles are especially evident in recent years on Colorado's western slope, including Rocky Mountain National Park (RMNP) with a severe epidemic of mountain pine beetle occurring in Grand County.   Mountain pine beetle and fire interactions with blister rust spread. For sugar pine, the presence of MPB was associated with blister rust infections. The link between MPB and blister rust is a common pattern found in montane regions (Campbell and Antos , Schwandt and Kegley, , Larson , Bockino and Tinker ).   To reflect the impact of high temperatures on mountain pine beetle emergence and dispersal (Safranyik and Carroll, ), we included the maximum temperature over the spring and e mountain pine beetle larvae are very sensitive to sudden changes in minimum temperatures in the fall, winter, and spring (Safranyik, ), we included the cold tolerance metric .
