Differential transmission of strawberry mottle virus by Chaetosiphon thomas Hille Ris Lambers and Chaetosiphon fragaefolii (Cockerell)

Creator:: Eulensen, Gustav Egon
Abstract:: The transmission of strawberry mottle virus (SMV) to Fragaria vesca L. by Chaetosiphon thomasi and C. fragaefolii was studied to determine differences between the two species. Acquisition, inoculation, and retention phases of transmission were described. In all phases, C. fragaefolii was found to be the more efficient vector. Mean transmission...

Ion exchange membranes and agronomic responses as tools for assessing nutrient availability

Creator:: Salisbury, Steven Earl
Abstract:: Winter wheat is commonly grown in rotation with leguminous and non-leguminous crops in the Willamette Valley. For agronomic, economic, and environmental reasons it is important to understand the influence of previous crops on availability of N and other nutrients. Objectives of this study were: (1) to evaluate the effects of...

Assessment of black vine weevil larval damage to cranberries and development of alternative control strategies

Creator:: Miller, Elizabeth A. (Elizabeth Ann)
Abstract:: Black vine weevil (BVW), Otiorhynchus sulcatus Fabricius, is a serious pest in cranberry, Vaccinium macrocarpon. Larvae feeding below the soil surface cause damage to the roots and underground stems. Knowledge is sparse in regard to the damage potential of BVW in Pacific Northwest cranberry beds. Control with insecticides is limited...

Effects of tillage on emergence of mint root borer, Fumibotys fumalis Guenée, and on other agronomic factors in peppermint, Mentha piperita L.

Creator:: Talkington, Michael Lee
Abstract:: Studies were conducted in the Willamette Valley of western Oregon to evaluate the effects of plowing (7.5-15 cm deep) and disking (5-10 cm deep) in peppermint, Mentha piperita L., on the following factors: 1) emergence of adult "mint root borer", Fumibotys fumalis Guenée; 2) suppression of common groundsel, Senecio vulgaris...
Resource Type:: Masters Thesis
Full Text:: quality and maturity. Plowing and disking significantly reduced emergence of adult r. fusalis. In all

Applications of radiotelemetry to studies of California quail in western Oregon

Creator:: Kilbride, Kevin M.
Abstract:: A partially automated radio-tracking system with semi-continuous azimuth data collection and XYLOG5 and MAP computer programs for azimuth data analysis was used for studies of California quail (Callipepla californica) at the E.E. Wilson Wildlife Area, Oregon, in 1988 and 1989. Movements of 58 hens were monitored daily to determine nest...

Biology and management of the obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), in sweet cherry

Creator:: Omeg, Michael Kent
Abstract:: The seasonal biology of the obliquebanded leafroller, Choristoneura rosaceana (Harris), was studied to improve its management in Mid-Columbia area sweet cherry orchards. Overwintering OBLR larvae began to emerge from hibernacula at bud stage 2 (side green). Most overwintering larvae emerged from hibernacula within three weeks of first bud swell and...
