This dataset contains records of identified benthic and aquatic emergent invertebrates from pre-timber harvest, post-timber harvest, and reference (no harvest) collection sites in the Hinkle Creek watershed. A variety of fish-bearing tributaries, fishless tributaries, and mainstem creek sites were sampled. Benthic invertebrates were collected using Serber nets and emergent adults...
Beneficial insects could provide valuable pest control services on Oregon Christmas tree farms, but a limited amount of data exist that quantifies the type and abundance of beneficial insects on farms. This study surveyed beneficial insects on two farms that differed in their management strategies as well as other abiotic...

Potato (Solanum tuberosum L.) is the fourth largest food crop in the world following rice (Oryza sativa L.), wheat (Triticum spp.), and maize (Zea mays subs. mays). Potatoes arrived in the United States in the early 1600s and over the following centuries, the crop was subsequently cultivated across the country...
Rivers impacted by human activities often have multiple stressors present. The effects of multiple stressors on biological communities can often be difficult to predict, due to the potential for complex interactions between stressors and communities. This thesis explores the impacts of two stressors often associated with agricultural land use, increased...
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...
A pheromone lure baited with the sex pheromone of grape mealybug is the most reliable way to confirm the presence or absence of this important vector of grapevine leafroll-associated viruses.
Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in...
Dalmatian toadflax (Linaria dalmatica) has become a prolific invasive plant of rangelands in Oregon since its arrival in the early 20th century. In 2001, the Oregon Department of Agriculture initiated a release program promoting the distribution of the stem-boring weevil, Mecinus janthinus as classical biological control agent to reduce densities...
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...
