The western pine beetle, Dendroctonus brevicomis LeConte, begins the attack of its host, ponderosa pine (Pinusponderosa Doug. ex. Laws.), when a female penetrates the bark and excavates a gallery in the phloem. The attractive pheromone component, exo-brevicomin, is produced in females.

Pseudopityophthorus pubipennis, the western oak bark beetle, is a species of typical bark beetle in the family Curculionidae. It is found in North America.

Mielke,USDA Forest. 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.

Diagnosis. Pseudopityophthorus is distinguished from the similar Pityophthorus Eichhoff by the reduced or absent striae and the more abundant and sometimes scale-like elytral can also be differentiated by the more elaborate frontal vestiture present on the male.

The rows of pronotal asperities are similarly arranged but are separated and do not form contiguous bands. bark and ambrosia beetles: Hylesinini: Tomicina: Dendroctonus terebrans (Olivier, ) western ash bark beetle: Hylesinini: Hylesinina: Hylesinus crenatus (Fabricius, ) small oak bark beetle: Scolytini: Pityophthorina: Pseudopityophthorus pruinosus (Eichhoff, ).

Developed by the University of Georgia Bugwood Network in cooperation with USDA Forest Service - Forest Health Protection, USDA APHIS PPQ, Georgia Forestry Commission, Texas Forest Service. At each location 1 tree was felled, 1 was given the West Virginia oak Pseudopityophthorus pubinpennis book control treatment (deep girdle with bark stripped off below the girdle to the ground level), and 1 tree was not treated.

About 1/4 of the boles and 2/3 of the branches of the test trees were attacked by the bark beetle Pseudopityophthorus pruinosus (Eichoff).Cited by: 6. western oak bark beetle (Pseudopityophthorus pubipennis) and ambrosia beetle (Monarthrum spp.) feed respectively on the bark (phloem) and sapwood of host trees.

Their feed-ing activity results in barely visible tunnels on the tree bark and in the production of finely ground frass (chewed phloem or sapwood) that ac-cumulates, often in large. Type species.

Atkinson Bark and Ambrosia beetle pages: Home Bark and Ambrosia Beetles. Life Cycle: The female beetle enters the bark and constructs a short entrance tunnel and an oblique nuptial chamber cut in the phloem. After mating in this chamber, the female constructs a single, long egg gallery.

The gallery may wander and even double back on itself, but generally follows the wood grain and may be over a meterFile Size: KB. Evidence supports the existence of both high consumption and diet modification strategies in bark beetles.

Ayres et al. [] compared nitrogen budgets of two co-occurring bark beetles, Ips grandicollis and D. frontalis, which have different feeding strategies. Ips grandicollis is a non-mycangial beetle that constructs long feeding galleries in phloem.
