The influence of canopy type and seasons on adult aquatic insect emergence and riparian spiders in the Oregon Coast Range

Creator:: Premdas, Sharmila
Abstract:: The objective of my study was to examine differences in riparian tree and shrub composition associated with adult aquatic emergence and implications for terrestrial spiders in these sites. Seasonal abundance and biomass of adult emergent aquatic insects, riparian arthropod abundances and spider densities were compared between conifer- and hardwood-dominated sites...

Population and production ecology of Lipsothrix spp. (Diptera:Tipulidae)

Creator:: Dudley, Thomas L.
Abstract:: Craneflies of the genus Lipsothrix inhabit decomposing wood in streams. The life cycles and ecological relationships of L. nigrilinea (Doane) and L. fenderi Alexander were investigated to determine how they exploit and respond to the wood habitat and their role in degradation of woody debris in western Oregon. Surveys of...

Seasonal occurrence and abundance of insect pests and natural enemies in the Columbia Basin

Creator:: Klein, Matthew L.
Abstract:: 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...

Structuring habitat to conserve ground beetles (Coleoptera: Carabidae) and reduce summer annual weeds in agroecosystems

Creator:: Green, Jessica M.
Abstract:: Weed management in sustainable farming systems often requires the integration of several different pest management techniques. Cultural, biological, and chemical pest control efforts can be utilized to contribute to the common goal of reducing weeds in vegetable row crop systems. This research addresses how common disturbances such as tillage and...

Using stable isotopes and visual gut examination to determine the diet composition of Pterostichus melanarius (Coleoptera: Carabidae) in western Oregon vegetable row crops

Creator:: Moulton, Laurel A.
Abstract:: The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...

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®)...

Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Creator:: Madson, Stephanie Lee
Abstract:: The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to...

Population and community ecology of the red alga Rhodomela larix (Turner) C. Agardh, on the central Oregon coast

Creator:: D'Antonio, Carla Marie, 1956-
Abstract:: Aspects of the life history and ecology of the intertidal turf-forming alga Rhodomela larix (Turner) C. Agardh were examined over a two year period at several sites on the Oregon coast. Rhodomela occurred over a broad tidal range and exhibited different growth and morphology characteristics with respect to tidal height....

Toward a continuous culture of bumble bees (Bombus Latr.)

Creator:: Seibert, Thomas Floyd
Abstract:: Out of 53 queens captured for initiating colonies in the laboratory, 33 laid eggs (62 percent), 29 of these produced colonies (55 percent), and 14 produced queens (26 percent). A behavioral model depicts the activities of queens from spring emergence through colony development. A discussion of its application to bumble...
