Multipartite Symbioses Among Fungi, Mites, Nematodes, and the Spruce Beetle, Dendroctonus rufipennis (2008)

Yasmin J. Cardoza, John C. Moser, Kier D. Klepzig, Kenneth F. Raffa

The spruce beetle, Dendroctonus rufipennis, is an eruptive forest pest of significant economic and ecological importance. D. rufipennis has symbiotic associations with a number of microorganisms,...

Seasonal Dynamics of Mites and Fungi and Their Interaction with Southern Pine Beetle (2006)

Richard W. Hofstetter, Kier D. Klepzig, John C. Moser, Matthew P. Ayres

We evaluated whether Dendroctonus frontalis Zimmermann populations were influenced by nontrophic interactions involving commensal mites, their mutualistic bluestain fungus Ophiostoma minus (Hedgc.)...

Effects of Diterpene Acids on Components of a Conifer Bark Beetle–Fungal Interaction: Tolerance by Ips pini and Sensitivity by Its Associate Ophiostoma ips (2005)

Brian J. Kopper, Barbara L. Illman, Philip J. Kersten, Kier D. Klepzig, Kenneth F. Raffa

Conifer resin and phloem tissue contain several phytochemical groups, composed primarily of monoterpenes, diterpene acids, and stilbene phenolics. The effects of monoterpenes and phenolics on...

Interactions of Hylastes Species (Coleoptera: Scolytidae) with Leptographium Species Associated with Loblolly Pine Decline (2004)

Lori G. Eckhardt, Richard A. Goyer, Kier D. Klepzig, John P. Jones

Hylastes spp. (Coleoptera: Scolytidae) were evaluated as potential vectors of Leptographium spp. fungi. Bark beetles were trapped from stands of loblolly pine, Pinus taeda L., exhibiting a range of...

Components of Antagonism and Mutualism in Ips pini–Fungal Interactions: Relationship to a Life History of Colonizing Highly Stressed and Dead Trees (2004)

Brian J. Kopper, Kier D. Klepzig, Kenneth F. Raffa

Efforts to describe the complex relationships between bark beetles and the ophiostomatoid (stain) fungi they transport have largely resulted in a dichotomous classification. These symbioses have been...

Relative Suitability of Virginia Pine and Loblolly Pine as Host Species for Dendroctonus frontalis (Coleoptera: Scolytidae) (2003)

Jessica S. Veysey, Matthew P. Ayres, María J. Lombardero, Richard W. Hofstetter, Kier D. Klepzig

Dendroctonus frontalis Zimmerman is a major disturbance agent in American pine forests, but attack preferences for various host species, and their relative suitability for reproduction, are poorly...
