Inducing and Evaluating Phenotypic and Cytometric Variation in Landscape Plants : Observations from Acer, Ornithogalum, and Penstemon

Creator:: Lattier, Kim Shearer
Abstract:: Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....

Evaluation of grapevine red blotch virus epidemiology with reference to potential insect vectors

Creator:: Dalton, Daniel T.
Abstract:: Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....

Behavior of Drosophila suzukii in Relation to Abiotic, Biotic, and Nutrient Factors

Creator:: Park, Kyoo Rok
Abstract:: Drosophila suzukii (Diptera: Drosophilidae), is a serious pest in soft and stone fruit industries worldwide. The unique serrated ovipositor of female Drosophila suzukii allowed the species to reproduce in intact, ripening fruit before the harvest. Current control methods rely heavily on insecticide application, only becoming less profitable due to the...

Effects of Diet and Humidity on Drosophila suzukii Flight Performance

Creator:: Wong, Jessica S.
Abstract:: Drosophila suzukii is a global and economically significant pest of berries and other soft fruits. This insect can survive and reproduce under a wide variety of environmental conditions and with a substantial number of cultivated and wild hosts. Management of D. suzukii is commonly done with chemical control strategies. However,...

Physiological effects of non-nutritive sugars on the survivorship and fecundity of Drosophila suzukii (Diptera: Drosophilidae)

Creator:: Tang, Siew Bee
Abstract:: Spotted wing drosophila (SWD), Drosophila suzukii, is an economically damaging pest on small fruits. The estimated economic impact is hundreds of millions of dollars annually in the U.S. alone, and increasing every year. Current control of SWD relies heavily on chemical insecticides which have many negative impacts on environmental and...

Influence of abiotic and biotic factors on developmental parameters of Drosophila suzukii (Diptera: Drosophilidae)

Creator:: Tochen, Samantha
Abstract:: Drosophila suzukii (Diptera: Drosophilidae), a pest of thin-skinned fruits, has been detected worldwide recently, with new locations of establishment determined annually since it first became a concern on continental North America in 2008. Drosophila suzukii females are different from most other drosophilids as being one of two known species capable...

Comparison of baits for monitoring the spotted wing Drosophila, Drosophila suzukii

Creator:: Kleiber, Joseph R.
Abstract:: Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...

Marking, movement, and management of Drosophila suzukii in Oregon berry crops

Creator:: Klick, Jimmy
Abstract:: Drosophila suzukii Matsumura (Diptera: Drosophilidae) are small invasive flies that in the past five years (2009-2014) invaded berry and stone fruit production regions in Europe and the Americas. Evolutionary adaptations, biological traits, and anthropogenic factors have contributed to its current status as a global pest. Females oviposit eggs into ripe...

Effect of several apple rootstocks on growth, yield components and leaf area estimates on "Starkspur Supreme Delicious" trees

Creator:: Siller-Cepeda, Jorge H.
Abstract:: Growth, yield components and leaf area were evaluated on 'Starkspur Supreme Delicious' apple on nine rootstocks: MAC 24, EMLA 7, EMLA 26, OAR 1, MAC 9, 0.3, EMLA 9, M 9, and EMLA 27. Estimates of planting density based on growth, estimates of leaf area based on four independent variables...
