Onion Thrips (Thysanoptera: Thripidae) and Their Management in the Treasure Valley of the Pacific Northwest

Creator:: Reitz, Stuart R.
Abstract:: Onion thrips, Thrips tabaci Lindeman and thrips-transmitted Iris yellow spot virus are the most significant pest complex affecting onion production in the Treasure Valley of eastern Oregon and southwestern Idaho. Thrips feeding damage and virus infection significantly reduce onion bulb size and economic returns for this high value crop. The...

Parametric manifolds. II. Intrinsic approach

Creator:: Boersma, Stuart and Dray, Tevian
Abstract:: A parametric manifold is a manifold on which all tensor fields depend on an additional parameter, such as time, together with a parametric structure, namely a given (parametric) one‐form field. Such a manifold admits natural generalizations of Lie differentiation, exterior differentiation, and covariant differentiation, all based on a nonstandard action...

Parametric manifolds. I. Extrinsic approach

Creator:: Boersma, Stuart and Dray, Tevian
Abstract:: A parametric manifold can be viewed as the manifold of orbits of a (regular) foliation of a manifold by means of a family of curves. If the foliation is hypersurface orthogonal, the parametric manifold is equivalent to the one‐parameter family of hypersurfaces orthogonal to the curves, each of which inherits...

Metabolism of Nonesterified and Esterified Hydroxycinnamic Acids in Red Wines by Brettanomyces bruxellensis

Creator:: Schopp, Lauren M., Lee, Jungmin, Osborne, James P., Chescheir, Stuart C., and Edwards, Charles G.
Abstract:: While Brettanomyces can metabolize nonesterified hydroxycinnamic acids found in grape musts/wines (caffeic, p-coumaric, and ferulic acids), it was not known whether this yeast could utilize the corresponding tartaric acid esters (caftaric, p-coutaric, and fertaric acids, respectively). Red wines from Washington and Oregon were inoculated with B. bruxellensis, while hydroxycinnamic acids...

Production of microsclerotia of the fungal entomopathogen Lecanicillium lecanii (Hypocreales: Cordycipitaceae) as a biological control agent against soil-dwelling stages of Frankliniella occidentalis (Thysanoptera: Thripidae)

Creator:: Wang, Haihong, Lei, Zhongren, Reitz, Stuart, Li, Yinping, and Xu, Xuenong
Abstract:: Microsclerotia (MS) production by two isolates of Lecanicillium lecanii on various culture media is described, and the efficacy of MS against western flower thrips is evaluated. High concentrations of MS (2.9-3.1×10⁵•mL⁻¹) were produced in media with C: N ratios of 7.4:1 and 10.3:1 by isolate SN21. Bioassays using soil-incorporated MS...

Impacts on Natural Enemies and Competitor Thrips of Insecticides against the Western Flower Thrips (Thysanoptera: Thripidae) in Fruiting Vegetables

Creator:: Srivastava, Mrittunjai, Funderburk, Joe, Olson, Steve, Demirozer, Ozan, and Reitz, Stuart
Abstract:: Newer, selective insecticides with few negative impacts on natural enemies and competitor species are needed for effective, sustainable management of the western flower thrips, Frankliniella occidentalis (Pergande). The purpose of this study was to evaluate the impacts on natural enemies and competitor thrips species of insecticides used for control of...

Predicting branch diameters on second-growth Douglas-fir from tree-level descriptors

Creator:: Maguire, Douglas A., Johnston, Stuart R., and Cahill, James M.
Abstract:: The quality of lumber and veneer recovered from logs of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is directly influenced by the maximum limb size attained on the crop tree. Because limb sizes are influenced by standdensity regimes, a need has arisen for quantitative tools that link a wide array of silvicultural...

Molecular Survey for the Invasive Leafminer Pest Liriomyza huidobrensis (Diptera: Agromyzidae) in California Uncovers Only the Native Pest Liriomyza langei

Creator:: Scheffer, Sonja J., Lewis, Matthew L., Gaimari, Stephen D., and Reitz, Stuart R.
Abstract:: Liriomyza huidobrensis (Blanchard) is a highly destructive invasive leafminer pest currently causing extensive damage to vegetable and horticultural crops around the world. Liriomyza langei Frick is a leafminer pest native to California that cannot currently be morphologically distinguished from L. huidobrensis. We used a DNA-barcoding approach, a published PCR-RFLP method,...

A Dimensionless Invariant for Relative Size at Sex Change in Animals: Explanation and Implications

Creator:: Gardner, Andy, Allsop, David J., Charnov, Eric L., and West, Stuart A.
Abstract:: Recent comparative studies across sex-changing animals have found that the relative size and age at sex change are strikingly invariant. In particular, 91%–97% of the variation in size at sex change across species can be explained by the simple rule that individuals change sex when they reach 72% of their...

Stratigraphy and age of the Eocene Igtertivâ Formation basalts, alkaline pebbles and sediments of the Kap Dalton Group in the graben at Kap Dalton, East Greenland

Creator:: Larsen, Lotte M., Pedersen, Asger K., Sorensen, Erik Vest, Watt, W. Stuart, and Duncan, Robert A.
Abstract:: A NE–SW-trending graben at Kap Dalton on the Blosseville Kyst contains an at least 600 m thick succession of Eocene basalt lavas and sediments. The succession has been investigated by new field work, geochemical analysis and radiometric dating by the ⁴⁰Ar-³⁹Ar incremental heating method. The results show that the volcanic...
