Sound production in Scolytidae: Rivalry behavior of male Dendroctonus
beetles select trees ripe for infestation, drill through the bark, dig a gallery in the cambium layer, and lay eggs.
Central British Columbia is currently subject to the largest recorded outbreak of mountain pine beetle (MPB; Dendroctonus
Researchers in the Sawtooths measuring phloem temperatures, where Dendroctonus
eggs over-winter, found that annual minimum phloem temperatures had "increased significantly" between 1980 and 2006.
In the mountain pine beetle, Dendroctonus
ponderosae Hopkins, a lack of diapause makes it less dependent on hormonal controls than in diapausing insects (Merivee 1978; Somme 1982; Hodkova & Hodek 1994).
Effect of silhouette color on trap catches of Dendroctonus
frontalis (Coleoptera: Scolytidae).
Among the bark beetles, there are major forest pests which have been well studied, including the southern pine beetle, Dendroctonus
frontalis Zimmerman (Chellman & Wilkinson 1980), the western pine engraver, Ips pini (Say) (Kegley et al.
Nutrient-mediated germination of Beauveria bassiana conidia on the integument of the bark beetle Dendroctonus
ponderosae (Coleoptera: Scolytidae).
Catches of 2 common bark beetles, Dendroctonus
terebrans (Olivier) and Ips grandicollis (Eichhoff), were unaffected by trap length.
Whereas we could not find reports of this genus as a predator of Scolytinae, it is important to note that other Monotomidae (Rhizophagus grandis Gyllenhal) have been reported as specific predators of the great spruce bark beetle, Dendroctonus
micans Erichson (Coleoptera: Curculionidae) (Meurisse et al.
Abstract--The red turpentine beetle (RTB), Dendroctonus
valens LeConte (Coleoptera: Curculionidae), which is native to North America, is an invasive wood-boring insect species in China with disastrous consequences.
While there are many species of bark beetles in our forests, including many species of pine beetles, the one that is currently causing widespread mortality of pines across the west is the mountain pine beetle, Dendroctonus
Carta's recent SEM-aided collaborations include working with a team of researchers led by Cetin Yuceer from Mississippi State University and including scientists from the University of Chicago, Davidson College, Hendrix College, and the USDA Forest Service to identify a new nematode species that's associated with the southern pine beetle, Dendroctonus
However, the southern pine beetle, Dendroctonus
frontalis, has been very detrimental.
Studies on avian predators of Dendroctonus
brevicomis LeConte (Coleoptera: Scolytidae) with special reference to Picidae.
