Etiology and pathogenesis of chalkbrood in the alfalfa leafcutting bee, Megachile rotundata

Creator:: Vandenberg, J. D. (John Donald)
Abstract:: Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee, Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed growers in western North America who use populations of this bee for pollination. Basic studies were conducted to determine the etiology of this disease and the course of...

Characteristics of NADPH-cytochrome P-450 reductase in the house fly (Musca domestica, L.) and the blow fly (Phormia regina, Meigen)

Creator:: Vincent, Daniel R.
Abstract:: NADPH-cytochrome P-450 reductase, an important enzyme in the cytochrome P-450-dependent microsomal monooxygenase system, was purified from insecticide-resistant (R) and -susceptible (S) house flies (Musca domestica, L.) and from the black blow fly (Phormia regina, Weigen). Proteolytic degradation to a P-450 - inactive form of the reductase was reduced during the...

Molybdenum status of subclover (Trifolium subterraneum) as affected by Mo and S fertilization and soil type

Creator:: Jarrell, Wesley M.
Abstract:: Field studies designed to study residual effects from fertilizer molybdenum were initiated in September 1971 on established grass-clover pastures at ten sites in Western Oregon. Treatments were 0.0 and 1.12 kg molybdenum /ha on plots receiving 0-35-0-20S fertilizer (elemental sulfur-S) and 0.0, 0.56, 1.12 and 2.24 kg molybdenum /ha on...

Biological studies on Saldula palustris (Douglas) with emphasis on factors influencing wing pigmentation (Heteroptera:Saldidae)

Creator:: Stock, Mary Wilford
Abstract:: The life history and wing pattern variation of the intertidal shore bug, Saldula palustris (Douglas), were studied in field and experimental populations from June 1970 until February 1972. The study site was an estuarine salt marsh on Yaquina Bay near Toledo, Oregon. The insects live below mean high water level...

John Wesley Powell : science and reform in a positive context

Creator:: Zernel, John Joseph, 1945-
Abstract:: John Wesley Powell worked actively for public land system reform while a director of geographical and geological surveys in the West from 1869 to 1894. Although this has won him acclaim as a conservationist, the basis of Powell's linkage of reform with scientific work is poorly understood. A study of...

Paleomagnetic inclination shallowing in deep-sea sediments

Creator:: Arason, Pórdur
Abstract:: In this thesis anomalous downcore shallowing of paleomagnetic inclinations is interpreted to be caused by sediment compaction. Thus, compaction-induced inclination shallowing may influence tectonic reconstructions that are based on inclinations from deep-sea sediment cores. Progressive downcore shallowing of the remanent inclination was observed in a 120-m section of Plio- Pleistocene...

Evaluation of grapevine red blotch virus epidemiology with reference to potential insect vectors

Creator:: Dalton, Daniel T.
Abstract:: Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....

Combustion Characteristics of a Jet Fuel and its Surrogate in MILD Conditions

Creator:: Weide, Parker D.
Abstract:: This research seeks to identify how changes in temperature and oxygen concentration in the reaction zone affects liftoff heights for moderate or intense low-oxygen dilution (MILD) combustion of a jet fuel and a surrogate fuel. MILD combustion offers a method of burning fuels with reduced CO and NOx production by...
