Status, distribution and seasonal variation of filbert aphid resistance to selected insecticides in the Willamette Valley, Oregon

Creator:

Katundu, Juma

Abstract:

Levels of resistance to six selected insecticides of eleven field populations of the filbert aphid Mvzocallis coryli (Goetze) were determined by using the leaf-dip residue technique. Test insecticides included compounds widely used in commercial filbert orchards, namely, carbaryl, diazinon, endosulfan, phosalone, fenvalerate and oxydemetonmethyl. Aphid samples were collected within a...

DNA markers linked to novel sources of resistance to eastern filbert blight in European hazelnut (Corylus avellana L.)

Creator:

Sathuvalli, Vidyasagar R.

Abstract:

The hundred-year history of the hazelnut industry in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. Marker-assisted selection (MAS) has been extensively used for ‘Gasaway’ resistance in the hazelnut breeding program at Oregon State University. Concern over breakdown of...

Classical biological control of the filbert aphid, Myzocallis coryli (Goetze) (Homoptera:Aphididae) in western Oregon

Creator:

Messing, Russell H.

Abstract:

A classical biological control project was undertaken against the filbert aphid, Myzocallis coryli (Goetze), in western Oregon. Hazelnut orchards in Spain, France, and Italy were searched for natural enemies of the aphid, and a parasitic wasp, Trioxys pallidus Haliday, was imported, quarantined, mass-reared, and released in Oregon orchards. The wasp...

The biology and seasonality of the parasitiod Trioxys pallidus Haliday in western Oregon

Creator:

Cohn, Judy L.

Abstract:

Seasonal synchrony between the filbert aphid, Myzocallis coryli (Goetze) and its newly introduced parasitoid Trioxys pallidus Haliday was examined in the field to evaluate the effectiveness of parasitoid based biological control in filbert orchards of Oregon. Fieldemergence observations showed that 50% eclosion of the aphid occurred 14 days before that...

Structure, function, and analysis of Coleoptera and Heteroptera assemblages on two species of hazelnut in Oregon

Creator:

Wetherill, Karen R.

Abstract:

The European hazelnut, Corylus avellana L., was imported into the U.S. in the late 1800's and is now grown throughout the Willamette Valley in Oregon. A native species of hazelnut, C. cornuta Marshall, is a common shrub found in forested areas of the Pacific Northwest. Foliage of both C. avellana...

Toxicity of some commonly used pesticides to Trioxys Pallidus and its establishment in filbert orchards of Willamette Valley

Creator:

Saeed, Mohammad

Abstract:

A parasitic wasp, Trioxys pallidus Haliday (Hymenoptera: Aphidiidae) was imported from Europe and initially released against the filbert aphid Mvzocallis coryli (Goetze) in hazelnut (filbert) orchards of the Willamette Valley, Oregon beginning in 1984. In the present study, I investigated the establishment rates of this parasitoid. A total of 13...

DNA markers and characterization of novel sources of eastern filbert blight resistance in European hazelnut (Corylus avellana L.)

Creator:

Peterschmidt, Brooke C.

Abstract:

European hazelnut is a significant crop in the Pacific Northwest, and the US ranks 4th internationally for hazelnut production. Production in the Pacific Northwest is threatened, however, by the disease eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. To meet the challenges faced by the...

Creator:

Mulvey, Robin L.

Abstract:

The primary objective of this research was to determine if native species within the genera Castilleja and Pedicularis are naturally infected by white pine blister rust (Cronartium ribicola) in whitebark pine ecosystems of the Oregon and Washington Cascade Range. Secondary objectives were to monitor the phenology of aecial and telial...

Biology of sweet cherry powdery mildew

Creator:

Calabro, Jill M.

Abstract:

The Pacific Northwest has become one of the nation’s premier sweet cherry, Prunus avium, production areas. As production of sweet cherries has flourished in Oregon and Washington, so has powdery mildew, caused by the fungus Podosphaera clandestina, which infects both foliage and fruit causing severe economic damage to growers. Sweet...

Facilitating plant-parasitic nematode management decisions for Washington Vitis vinifera growers : determining the spatial distribution of plant-parasitic nematodes and the host status of Vitis spp. to Meloidogyne hapla

Creator:

Howland, Amanda D.

Abstract:

A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...
