Monitoring pesticide resistance in Psylla pyricola Foerster from western Oregon pear orchards

Creator:: Follett, Peter A.
Abstract:: A modified slide-dip bioassay was used to survey and establish baseline resistance levels in Psylla pyricola Foerster from western Oregon orchards to four pesticides. Orchards selected in the Hood River, Rogue River and Willamette Valleys spanned a wide range of environmental and management conditions. During the study period of 1982-1983,...

Steady-State Diffusion in a Spatially Varying Porous Medium

Creator:: Ferrero, Peter T.
Abstract:: Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...

Experimental and theoretical analysis of radial porosity in a monodisperse sphere packing

Creator:: Nakamoto, Nathan
Abstract:: This thesis presents an experimental study of radial porosity in a manually filled cylindrical container with glass spheres. The symmetric distribution of bead diameter allowed for normalization of container properties and porosity models. The aspect ratio of the container was approximately 3.9, with tube-to-particle-diameter ratio λ ≈ 24.6 and height-to-particle-diameter...

Natural circulation scaling of a pressurized conduction cooldown event in the upper plenum of the modular high temperature gas reactor

Creator:: King, Brian M.
Abstract:: In a Modular High Temperature Gas Reactor (MHGTR), the Pressurized Conduction Cooldown (PCC) event is an accident scenario in which there is a loss of forced convection of the coolant through the system but the pressure boundary remains intact. When the PCC event occurs, natural circulation onsets which results in...

Biological control of spider mites (Acari: Tetranychidae) on grape emphasizing regional aspects

Creator:: Prischmann, Deirdre A.
Abstract:: During summer of 1998 and 1999, 34 and 10 vineyard sites, respectively, were sampled to assess spider mite pests and associated biological control by phytoseiid mites. Vineyards studied spanned five major valleys in western Oregon where grape production occurs. Leaf samples were taken from site perimeters and centers. One leaf...

Jerking behavior among phytoseiid mite species (Acari: Phytoseiidae)

Creator:: Blackwood, J. Scott
Abstract:: Jerking, which we defined as a pronounced and often repeated lunging of the entire body, was studied in larvae among seven species of phytoseiid mites, and in the nymphal stages of Neoseiulus fallacis (Garman). This behavior was observed in all active immature stages of N. fallacis, and in larvae of...

Within and between plant dispersal and distributions of adult females and immatures of Neoseiulus californicus and N. fallacis (Acari: Phytoseiidae) in bean and apple plant systems

Creator:: Pratt, Paul D. (Paul David), 1970-
Abstract:: Intra- and interplant movement and dispersal of the predator mites Neoseiulus californicus (McGregor) and Neoseiulus fallacis (Garman) were studied on both lima bean (Phaseolus lunatus L.) and apple (Malus pumila Miller) branch plant systems that were seeded with excess numbers of the spider mite Tetranychus urticae Koch. Individuals of either...

Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...
