  • The economic value of native pollinators in regard to Oregon blueberry production

    Creator:
    Ritter, Daniel J.
    Abstract:
    Blueberry production in Oregon is highly reliant upon the ecosystem services of native pollinators, which provide as much as a quarter of the total pollination services received by Blueberry growers. However, the health of these pollinator populations may be affected in yet unforeseen ways as growers adopt new pest management...

  • Grape Powdery Mildew Management: The Interaction Between Inflorescence Stage and Fungicide Chemistry

    Creator:
    Warneke, Brent W.
    Abstract:
    Grape powdery mildew (GPM, causal agent Erysiphe necator) is the most economically important disease of grapevine in the Western U.S. Low levels of GPM infection on clusters (1-5%) can negatively affect wine sensory quality, so intensive fungicide programs are common. This may lead to problems like excessive fungicide use and...

  • Comparison of baits for monitoring the spotted wing Drosophila, Drosophila suzukii

    Creator:
    Kleiber, Joseph R.
    Abstract:
    Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...

  • Marking, movement, and management of Drosophila suzukii in Oregon berry crops

    Creator:
    Klick, Jimmy
    Abstract:
    Drosophila suzukii Matsumura (Diptera: Drosophilidae) are small invasive flies that in the past five years (2009-2014) invaded berry and stone fruit production regions in Europe and the Americas. Evolutionary adaptations, biological traits, and anthropogenic factors have contributed to its current status as a global pest. Females oviposit eggs into ripe...
