Documentation of the side effects of pesticides on
arthropod natural enemies has expanded rapidly since the
1950's as part of an increase in non-target side effects
literature. Most reviews have been based on empirical
analysis of selected literature. The SELCTV database was
developed to make a larger information base accessible...
During summer of 1998 and 1999, 34 and 10 vineyard sites, respectively, were sampled to assess spider mite pests and associated biological control by phytoseiid mites. Vineyards studied spanned five major valleys in western Oregon where grape production occurs. Leaf samples were taken from site perimeters and centers. One leaf...
Brook trout (Salvelinus fontinalis) populations currently exist in less than half of their historic range in the state of New Jersey. The remaining populations are confined to the northwestern part of the state in the Highlands, Appalachian Ridge and Valley, and Piedmont physiographic provinces, with the exception of Mason's Run,...
The diamondback moth (Plutella xylostella L.) is a major
pest of crucifer crops worldwide. It is a particularly
important problem in Southeast Asia where climatic
conditions favor a short generation time and rapid
proliferation. In countries such as Thailand, the
diamondback moth has apparently become resistant to all
classes of...
An outbreak of western spruce budworm Choristoneura
occidentalis in the Blue Mountains of eastern Oregon in
1983 was treated with helicopter applied carbaryl. Effects
of the spraying on forest ants were determined from pre- and
postspray samples taken from two carbaryl sprayed and
two unsprayed plots. In each 0.75-ha plot,...
Humpback whale populations in Antarctica are recovering after intensecommercial whaling in the 20th century. Along the Western Antarctic Peninsula (WAP)this recovery is occurring in an environment that is experiencing the fastest warming ofany region on the planet. To begin to understand the dynamics of this recovery undersuch dramatic climate change,...
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...
Using bulked segregant analysis, five RAPD markers were identified that were
linked in coupling to a gene conferring complete resistance to eastern filbert blight caused
by Anisogramma anomala (Peck) E. Muller in hazelnut (Corylus avellana L.). Two
modified backcross populations were inoculated and scored for resistance to the pathogen
and...
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...
Viability and dispersal of ascospores of Anisogramma anomala, the cause of eastern filbert blight (EFB) on European hazelnut, from diseased branches pruned from trees were measured. In each of two years, branches bearing stromata of A. anomala were cut in mid-December and compared to branches cut near budbreak in March,...
