Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

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...

Efficacy of entomopathogenic fungi for control of the cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae)

Creator:: Snelling, Jane E.
Abstract:: The cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae) is a serious pest of cruciferous crops (i.e. broccoli, cabbage, turnip, rutabaga) in North America and Europe (Coaker and Finch, 1971; Whistlecraft et al., 1985). The adult flies lay eggs around the base and in cracks at the soil surface around wild...

An evaluation of factors influencing the management of Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae)

Creator:: Kepler, Ryan M.
Abstract:: The black vine weevil (BVW), Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae) is a persistent pest of nursery operations in the United States, feeding on over 140 species of plants. The goals of this research were to 1) assess the behavioral response of BVW to a commonly employed insecticide bifenthrin (Talstar 0.2G®)...

Survey of rhizosphere associated entomopathogenic fungi on small fruits and Christmas trees in the Willamette Valley, OR

Creator:: Fisher, Joanna J.
Abstract:: The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are commercially available as microbial control agents for the black vine weevil, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), the key root-feeding insect pest in Pacific Northwest small fruits and ornamentals. Understanding habitat selection is critical to improve the efficacy, persistence and cost of...

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...

Modeling the Economic Potential of Silvopasture in Eastern North Carolina and Northeastern Oregon and Exploring Eligibility of Silvopasture to Enroll in Carbon Markets in the United States

Creator:: Bruck, Sonia Rose
Abstract:: Silvopasture is the planned and managed agroforestry system in which forage, livestock, and trees or shrubs are integrated in order to enhance individual components. Silvopasture has been identified as the most promising agroforestry system for the Pacific Northwest and Southeast United States. However, there have been few studies describing the...

Who Benefits from Development Aid? Exploring Agroforestry Technology Adoption, Food Security, and Path Dependence in Rural Tanzania

Creator:: Bruck, Sonia R.
Abstract:: Rural farmers in Tanzania depend on subsistence agriculture for their livelihood. Poor soil conditions, and the danger of drought, increases the risk of cyclical poverty conditions. Aid organizations, including the World Agroforestry Centre (ICRAF) and the Millennium Development Projects (MDP), as well as industrial tobacco industry, have provided development programs...

Assessment of black vine weevil larval damage to cranberries and development of alternative control strategies

Creator:: Miller, Elizabeth A. (Elizabeth Ann)
Abstract:: Black vine weevil (BVW), Otiorhynchus sulcatus Fabricius, is a serious pest in cranberry, Vaccinium macrocarpon. Larvae feeding below the soil surface cause damage to the roots and underground stems. Knowledge is sparse in regard to the damage potential of BVW in Pacific Northwest cranberry beds. Control with insecticides is limited...
