  • Management of powder-post beetles, Dinoderus minutus F. in freshly cut bamboo

    Creator:
    Garcia, Carlos Manalo
    Abstract:
    The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and ftmgi associated with beetles were investigated. Finally, the...

  • Fungal colonization of Douglas-fir sapwood

    Creator:
    Kang, Sung-Mo
    Abstract:
    The fungi that cause mold and stain of freshly sawn lumber result in millions of dollars in losses to the forest products industry. Stain and mold are typically prevented by either kiln drying or by application of a topical fungicide. While these treatments are effective, kiln drying is costly and...

  • The role of lytic enzymes in biocontrol of sapstain fungi

    Creator:
    Liu, Jiajian
    Abstract:
    The biocontrol potential of Trichoderma harzianum strains B-2A, B-8A, B-4B, B-15B, and B-41 and Serratia plymuthica was evaluated using agar plates and wood wafers of unseasoned ponderosa pine (Pinus ponderosa laws). All five isolates of Trichoderma harzianum and Serratia plymuthica could inhibit stain fungi growth in agar plates and exhibited...

  • Bioprotection of unseasoned Ponderosa pine lumber from microbial discoloration

    Creator:
    Kreber, Bernhard
    Abstract:
    The potential of 9 bacterial and 6 fungal isolates to protect wood against wood staining microorganisms was studied using small sapwood samples of unseasoned Ponderosa pine [Pinus ponderosa Laws] sapwood. Bacillus subtilis Cohn, isolate 733 A , Gliocladium virens J.H. Miller, J.E. Giddens & A.A. Foster isolate H 3 and...

  • Extraction of proteins from wood samples colonized by bioprotectants and/or stain fungi

    Creator:
    Cui, Li
    Abstract:
    Biological stain (blue stain) reduces wood value and prevents its use in many structural applications. Increasing environmental concerns have restricted the chemicals available for controlling this damage. As a result, biological control has received more interest. The application of these systems to wood has been limited due to their inability...
