Biology and Management of Pacific Flatheaded Borer, Chrysobothris mali, in Hazelnut

Creator:: Mugica, Anthony R.
Abstract:: Pacific flatheaded borer (PFB), Chrysobothris mali Horn (Coleoptera: Buprestidae), has recently become a serious pest in newly planted European hazelnut, Corylus avellana L. (Betulaceae) in Oregon. Larvae feeding on the inner bark can lead to girdling, loss of transpiration, and ultimately can cause dieback or death of the tree. Although...

Characterization and Cultivar Susceptibility Assessment of Bacterial Blight in Hazelnut Caused by Xanthomonas arboricola pv. corylina

Creator:: Webber, John B., III
Abstract:: Bacterial blight (Xanthomonas arboricola pv. corylina) (Xac) of hazelnut (Corylus avellana L.) was described first in Oregon in 1915 and is now recognized as a damaging disease of young hazelnut trees worldwide. Stressed hazelnut trees in conditions such as planting on marginal sites, and trees between 1 and 4-years-old are...

Determining the Impacts of Dormant Pruning Methods and Nitrogen Fertilization on Vitis vinifera 'Pinot noir' Bud Fruitfulness and Yield

Creator:: Ulmer, Miranda R.
Abstract:: The majority of grapes grown in Oregon are produced in Western Oregon’s Willamette Valley, where two-thirds of the acreage is planted to Pinot noir. The production of Pinot noir in the Willamette Valley comes at a high cost, and growers are seeking ways to increase profits while maintaining quality fruit...

Nutrient Profile and Nursery Feeding Damage of Halyomorpha halys (Hempitera: Pentatomidae)

Creator:: Skillman, Victoria P.
Abstract:: Halyomorpha halys Stål, brown marmorated stink bug or BMSB, is now present in 43 US states. A native of eastern Asia, this pest can feed on ~200 different plant species damaging bark, leaves, buds, stems, and fruits. Many of these plant species include wild plants, ornamentals, and agricultural crops. BMSB...

The Impact of Temperature on Halyomorpha halys (Hemiptera: Pentatomidae) Life Table Parameters and Feeding Pressure

Creator:: Maslen, Erika A.
Abstract:: Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive insect pest that has become established and problematic in the Pacific Northwest. Known colloquially as the brown marmorated stink bug (BMSB), H. halys causes direct damage through feeding activity on a wide range of agronomic and horticultural crops. The objectives of this...

The Role of Diurnal Light, Temperature, and Forced Egg Retention on Spotted Wing Drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae) Survival and Ovipositional Rates

Creator:: York, Riki M.
Abstract:: Drosophila suzukii (Diptera: Drosophilidae) is a devastating pest that attacks thin-skinned stone and small fruit in all major production regions of the United States and worldwide. D. suzukii first appeared in the United States in 2008 and is believed to be native to Southeast Asia. This vinegar fly has a...

Biotic and abiotic factors impacting development, behavior, phenology, and reproductive biology of Drosophila suzukii

Creator:: Hamby, Kelly A., Bellamy, David E., Chiu, Joanna C., Lee, Jana C., Walton, Vaughn M., Wiman, Nik G., York, Riki M., and Biondi, Antonio
Abstract:: Spotted wing drosophila, Drosophila suzukii, is a devastating invasive pest of small and stone fruits in the Americas and Europe. To better understand the population dynamics of D. suzukii, we reviewed recent work on juvenile development, adult reproduction, and seasonal variation in life history parameters including the abiotic/biotic factors that...

Breeding, Production, and Morphophysiology Among Cytotypes of Common and Portuguese Cherrylaurel

Creator:: Schulze, Justin A.
Abstract:: The common cherrylaurel (Prunus laurocerasus) and Portuguese cherrylaurel (P. lusitanica) are economically important landscape shrubs across the United States. To gain a better understanding of physiology and morphology in these higher level polyploids (P. lusitanica, 2n = 8x; P. laurocerasus, 2n =22x), a variety of breeding experiments were performed. The...
