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...

EXE, an expert system shell for agricutural applications

Creator:: Currans, Kevin
Abstract:: This paper discusses the design, construction, and use of a prototype expert system shell, EXE. EXE is non-conventional in that it does not provide a traditional forward or backward chaining inference mechanism. Instead, it allows the domain expert to control the logic flow of the system in a dynamic fashion....

Overwintering survival of stem rust on perennial ryegrass : construction of a simulation model, and effects of the mycoparasite Sphaerellopisis filum

Creator:: Gordon, Tyler C.
Abstract:: Stem rust, caused by the fungus Puccinia graminis subsp. graminicola, can cause yield reductions exceeding 90% on perennial ryegrass (Lolium perenne L.) crops grown for seed if not treated with fungicide in the spring. There is evidence that late-spring stem rust epidemics are initiated by populations that survived the winter....

Comparative emigration, immigration, and colonization of apple by Metaseiulus occidentalis Nesbitt and Typhlodromus pyri Scheuten (Acarina: Phytoseiidae)

Creator:: Dunley, John E.
Abstract:: Dispersal and colonization of young potted apple trees by the spider-mite predators Metaseiulus occidentalis Nesbitt and Typhlodromus pyri Scheuten were studied in the Hood River Valley of Oregon. Experimental mini-orchards of 10 four-year old potted apple trees were established at distances of 0, 10, and 100 m downwind from commercial...

Structure, function, and analysis of Coleoptera and Heteroptera assemblages on two species of hazelnut in Oregon

Creator:: Wetherill, Karen R.
Abstract:: The European hazelnut, Corylus avellana L., was imported into the U.S. in the late 1800's and is now grown throughout the Willamette Valley in Oregon. A native species of hazelnut, C. cornuta Marshall, is a common shrub found in forested areas of the Pacific Northwest. Foliage of both C. avellana...

Effect of in-servicing teachers on student achievement in integrated pest management

Creator:: Doerner, Robert W.
Abstract:: The primary purpose of this study was to determine if inservicing Agriculture Science and Technology (AST) teachers over a new curriculum, resulted in increased student achievement. Specific objectives were to: 1) determine the subject areas (lessons) for a curriculum for teaching Integrated Pest Management (IPM); 2) develop a curriculum for...

Tactics for enhancing conservation biological control of twospotted spider mites, Tetranychus urticae Koch, in Pacific Northwest hop yards

Creator:: Woods, Joanna L.
Abstract:: The twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a worldwide pest of numerous agronomic and horticultural plants. Conservation biological control of this pest can be unreliable due to asynchrony of natural enemies and certain horticultural practices that have a direct or indirect affect on natural enemies and the...

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...

Assessing landscape complexity using remotely sensed and field based measurements : does landscape complexity drive leafroller parasitism rates on Oregon caneberry farms?

Creator:: Winfield, Tammy L.
Abstract:: Landscape heterogeneity is thought to differ among farm management types (i.e. organic and conventional), and this difference is hypothesized to result in variations in pest control by natural enemies. However, it is unclear if these variations in pest control are driven by landscape structure or by farm management practices themselves....
