Phenology and monitoring of the cabbage maggot, Delia radicum (L.), in brassica root crops

Creator:: Dreves, Amy J.
Abstract:: In Oregon’s northern Willamette Valley, cabbage maggot (CM), Delia radicum (L.) (Diptera: Anthomyiidae) often renders Brassica root crops unmarketable. Scheduled insecticides are the only current control. Studies were conducted to: 1) describe and characterize spring emergence of CM flies and their seasonal flight activity relative to degree-day (DD) accumulations; 2)...

Orange tortrix : parasitoid complex and thermal constants for egg hatch

Creator:: Coop, Leonard Bryan
Abstract:: An investigation was conducted in 1980 and 1981 on the larval parasitoid complex of the orange tortrix, Argyrotaenia citrana (Fern.), a major contaminant in cane fruits (Rubus spp.) in the Pacific Northwest. A total of 13 parasitoid species were reared from 1,350 larvae predominantly collected from red raspberries in western...

Distribution of Oligonychus (Oligonychus) ununguis (Jacobi) (Acari: Tetranychidae) and predator mite species (Acair: Phytoseiidae) on field-grown Douglas-fir (Pseudotsuga menziesii [Mirb] Franco) Christmas trees

Creator:: Calkin, James D.
Abstract:: The shake and wash technique (samples placed in a jar with alcohol added and shaken to remove the mites) was effective in removing 100% of the predator mites, and adult spruce spider mites from Douglas-fir foliage and 98% of the spruce spider mite nymphs. Eighty-eight percent of the spruce spider...

Use of a geographical information system to modify pheromone trap-based predictions of Helicoverpa zea (Boddie) damage

Creator:: Drapek, Raymond James
Abstract:: The GRASS (V. 4.0) geographical information system (GIS) was used to test the hypothesis that pheromone trap based predictions of Helicoverpa zea (Boddie) damage in processed sweet corn could be improved by considering spatial patterns of corn plantings and wind blocking features around the trap. Wind blocking features include: tree...

Cereal stem moth, Ochsenheimeria vacculella Fischer von Röslerstamm (Lepidoptera : Ochsenheimeriidae) : field biology and larval development on selected grasses and cereals in Western Oregon

Creator:: Panasahatham, Sarote
Abstract:: The seasonal life history of the cereal stem moth (CSM), Ochsenheimeria vacculella Fischer von Roslerstamm, (Lepidoptera : Ochsenheimeriidae) was investigated in a commercial field of annual ryegrass in the Willamette Valley, OR from January 1993 to August 1994. Phenology of life stages, effect of temperature on eclosion, and development of...

Attractivity of plant volatiles and a semichemical-based bait to the western spotted cucumber beetle, Diabrotica undecimpunctata Mannerheim (Coleoptera: Chrysomelidae)

Creator:: Hongtrakul, Tawatchai
Abstract:: The adult western spotted cucumber beetle (WSCB), Diabrotica undecimpunctata undecimpunctata Mannerheim is considered a major pest of snap beans grown for processing in Western Oregon. Control consists of 1 or 2 insecticide sprays prior to harvest. A commercial semiochemical-based insecticide bait, Adios TIC®, 1.3% carbaryl + 5% buffalo gourd root...

Biology, ecology and management of Scaptomyza apicalis Hardy (Diptera : Drosophilidae) on meadowfoam, Limnanthes alba benth in western Oregon

Creator:: Panasahatham, Sarote
Abstract:: Biology of Scaptomyza apicalis Hardy (Diptera: Drosophilidae) was studied in relation to its host, meadowfoam, Limnanthes alba, a recent oil seed crop grown in the Willamette Valley, Oregon. Populations of flies and larvae were monitored weekly over three consecutive crop-years beginning in 1996. Yellow sticky traps gave relative population estimates...

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...

Field and greenhouse studies with Acalymma and Diabrotica : protection of cucurbits with a kaolin-based particle film : feeding damage to cucumbers with and without cucurbitacin

Creator:: Reich, Joel A.
Abstract:: Research was conducted in the field and greenhouse to determine if a kaolinite-based particle film, Surround®, would reduce colonization and early season feeding damage in cucurbits by the Western Striped Cucumber Beetle, Acalymma trivitattum (Mannerheim). Greenhouse studies were designed to determine effect of particle film on cucumber dry weight production...
