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)...

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...

Sampling and management of garden symphylans (Scutigerella immaculata Newport) in western Oregon

Creator:: Umble, Jon R.
Abstract:: Garden symphylans (Scutigerella immaculata Newport) are increasingly important pests of below-ground parts of over 100 crops in Oregon. The focus of our work was to improve S. immaculata management through 1) development of a bait sampling method, 2) examination of the susceptibility of selected crops to S. immaculata feeding in...

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...

Ascorbylation- the biological relevance of covalently bound ascorbic acid

Creator:: Kesinger, Nicholas G.
Abstract:: Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'. The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...

Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

Creator:: Zhang, Yong
Abstract:: Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...

Enhancing the predatory potential of hoverflies on aphids in Oregon broccoli fields with floral resources

Creator:: Ambrosino, Mario D.
Abstract:: Four key aspects of the relationship between predatory hoverflies and the aphid pest Brevicoryne brassicae L. on broccoli were investigated in the Willamette Valley, Oregon USA: 1) the relationship between aphid density and hoverfly oviposition, 2) the larval voracity of key hoverfly species, 3) the preferences of hoverflies and broccoli...
