Population dynamics of the Douglas-fir cone moth, Barbara colfaciana (Kft.) (Lepidoptera:Olethreutidae)

Creator:: Nebeker, T. Evan
Abstract:: A population of the Douglas-fir cone moth, Barbara colfaxiana (Kft. ), was studied on the Buckhead Seed Production Area, Oakridge, Oregon, during 1971 and 1972. A method of estimating cone and insect populations is presented. Factors contributing to the mortality of B. colfaxiana are discussed, with resinosis being the critical...

Insects associated with black stain root disease of Douglas-fir in western Oregon

Creator:: Witcosky, Jeffrey John
Abstract:: The root systems of Douglas-fir trees infected with Verticicladiella wagenerii and assigned by crown color and terminal growth characteristics to several stages of decline were excavated at three widely separated sites in the Coast Range of Oregon. Data were gathered on insect species present, extent of colonization of the root...

Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...

Pathogenesis and intertree transmission of Verticicladiella wageneri in Douglas-fir (Pseudotsuga menziesii)

Creator:: Hessburg, Paul F.
Abstract:: Verticicladiella wageneri Kendr. is a vascular wilt pathogen of Douglas-fir in the Pacific Northwest, The disease is characterized by black staining of colonized sapwood; crown symptoms are those typical of a wilting syndrome. Histopathological studies revealed that the pathogen is limited to the xylem but causes vascular dysfunction in both...

The root insect-- black-stain root disease association in Douglas-fir : vector relationships and implications for forest management

Creator:: Witcosky, Jeffrey John
Abstract:: Verticicladiella wageneri Kendrick is a vascular wilt pathogen of conifers, causing a black staining of colonized sapwood of roots and lower stem. In Douglas-fir, V. wageneri is intimately associated with insects. Hylastes nigrinus, Pissodes fasciatus, and Steremnuis carinatus are commonly associated with diseased hosts, carry inoculum of V. wageneri in...

Some silvicultural impacts of Phellinus weirii on a managed forest in the interior Coast Range of Oregon

Creator:: Lawson, Thomas Taylor
Abstract:: Phellinus weirii, the cause of laminated root rot, is considered the most destructive root rot of Douglas-fir, but little is known about the damage it causes, to a forest. The objective of this study was to determine silvicultural impacts of P. weirii on a managed forest. A survey located and...

The role of ethylene in ectomycorrhiza formation and Fusarium infection of Douglas fir roots

Creator:: Graham, James Herbert
Abstract:: The ectomycorrhizal fungi Cenococcum geophilum, Hebeloma crustuliniforme and Laccaria laccata produced ethylene in vitro in modified Melin-Norkrans liquid medium only if amended with 2.5 to 10 mM methionine; Pisolithus tinctorius failed to produce ethylene unless the cultures were renewed with fresh methionine-amended medium prior to ethylene assay. An additional 19...

Biology and control of Fusarium spp. on Douglas-fir (Pseudotsuga menziesii)

Creator:: Hoefnagels, Mariëlle Henriette, 1965-
Abstract:: Fusarium spp. are among the most important pathogens of Douglas-fir (Pseudotsuga menziesii) seedlings in bareroot nurseries. Currently the most effective disease control method is soil fumigation with methyl bromide. As methyl bromide is phased out, however, other disease management strategies may become more important. We explored two alternative approaches to...
