Importance of timber-related revenues to local governments in Oregon and the effects of forests in Oregon on property tax rates

Creator:: Hackworth, Kevin
Abstract:: Local governments in Oregon receive money from the forestry sector in a number of ways. This paper briefly describes public and private forestry sector sources and the relative importance of their payments to five forms of local governments by county for fiscal year 1982-83 to 1985-86. An analysis of the...

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,...

Application of laser spectroscopy to structure and dynamics of small molecular systems

Creator:: Bozlee, Brian J.
Abstract:: A variety of laser spectroscopic methods are employed in this thesis research for studies of CF₃NO, an interesting model photodissociative system, and for investigation of low energy rotations and vibrations of small molecules and low molecular weight clusters in free jet expansions. Nonradiative energy decay for electronically excited CF₃NO is...

Effects of irrigation frequency on yields of winter wheat

Creator:: Nakamura, Brian Clifford
Abstract:: Deliberately underirrigating a crop may yield economic benefits. The optimal use of water by an irrigator should be achieved under a deficit irrigation regime. It is important to know how water deficits affect yields and the interaction of the deficits with the scheduling of irrigations. A field experiment was conducted...

Ion-pair high pressure liquid chromatography techniques for the determination of quaternary ammonium compounds

Creator:: Starbuck, Brian J.
Abstract:: Quaternary Ammonium Compounds, Qams, are an important class of chemicals which present interesting challenges to analysts. This thesis reports results of investigations on uses of ion-pairing techniques for separations and detection of Qams. Special apparatus for post-column solvent extraction of liquid chromatographic eluates was developed as part of this work....

The influence of map complexity on interpolation accuracy.pdf

Creator:: Young, Brian K.
Abstract:: In this paper "map complexity" refers to the inherent intricacy of a mapped geographic pattern. Map complexity and sample size are two variables shown to influence the accuracy of interpolated dasymetric maps. An automated experiment was designed to investigate the precise relationship among map complexity, sample size, and the accuracy...

The SELCTV database : the susceptibility of arthropod natural enemies to agricultural pests to pesticides

Creator:: Theiling, Karen M.
Abstract:: Documentation of the side effects of pesticides on arthropod natural enemies has expanded rapidly since the 1950's as part of an increase in non-target side effects literature. Most reviews have been based on empirical analysis of selected literature. The SELCTV database was developed to make a larger information base accessible...

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,...

Chemotherapeutic and nontarget side-effects of benomyl to the orange tortrix (Argyrotaenia citrana) and the braconid endoparasite Apanteles aristotelia

Creator:: Sewall, David K.
Abstract:: Benomyl, a systemic benzimidazole fungicide was incorporated into artificial diet and evaluated for its oral toxicity to nonparasitized and parasitized third instar orange tortrix larvae, Argyrotaeniae citrana (Fernald) and its food chain toxicity via the host to the solitary braconid endoparasite Apanteles aristoteliae Vierek. Concentrations of benomyl ≤ 300 ppm...
