Enhancement of biological control with beneficial insectary plantings

Creator:: Colley, Micaela Ruth
Abstract:: Five field experiments were conducted to evaluate the relative attractiveness of potential beneficial insectary plants to aphidophagous hover flies and parasitic Hymenoptera and the effectiveness of interplanting selected flowering plants in a broccoli field to enhance biocontrol of the cabbage aphid and green peach aphid. In 1996 we established a...

Development of a Multiplex PCR for Identification of Vineyard Mealybugs

Creator:: Daane, Kent M., Middleton, Mathew C., Sforza, Rene, Cooper, Monica L., Walton, Vaughn M., Walsh, Douglas B., Zaviezo, Tania, and Almeida, Rodrigo P. P.
Abstract:: A simple molecular tool was developed and tested to identify seven mealybug species found in North American vineyards: Pseudococcus maritimus Ehrhorn, Pseudococcus viburni (Signoret), Pseudococcus longispinus (Targioni-Tozzeti), Pseudococcus calceolariae (Maskell), Planococcus fleas (Signoret), Planococcus citri (Risso), and Ferrisia gilli Gullan. The developed multiplex PCR is based on the mitochondrial cytochrome...

Strategies for machine harvesting of mature coffee (Coffea arabica L.) fruits

Creator:: Tongumpai, Peeradet
Abstract:: Greenhouse and field grown coffee plants were used to study the synchronization of flowering and fruiting. The purpose of these studies was to develop methods of improving the selective harvesting of mature coffee fruits by machine. The studies were divided into 4 parts: 1) Synchronization of flowering, 2) Synchronization of...

Evaluation of methyl salicylate lures on populations of Typhlodromus pyri (Acari: Phytoseiidae) and other natural enemies in western Oregon vineyards

Creator:: Gadino, Angela N., Walton, Vaughn M., and Lee, Jana C.
Abstract:: Methyl salicylate (MeSA), a herbivore-induced plant volatile, can elicit control of pests through attraction of beneficial arthropods. This study evaluates the effect of synthetic MeSA lures (PredaLure) on arthropod populations during the 2009 and 2010 seasons in two Oregon vineyards (Dayton and Salem). MeSA lures were deployed at a low...

Nitrogen fertigation practices to optimize growth and yield of northern highbush blueberry (Vaccinium corymbosum L.)

Creator:: Vargas, Oscar L.
Abstract:: Northern highbush blueberry is a long-lived perennial crop that is well adapted to low soil pH conditions. The plants are often shallow rooted and absorb primarily the ammonium (NH₄) form of nitrogen (N) rather than nitrate-N (NO₃-N). Traditionally, commercial blueberry fields have been irrigated with overhead sprinklers and fertilized using...

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...

The inheritance of pod detachment force in green beans (Phaseolus vulgaris L.)

Creator:: McCluskey, Rebecca L.
Abstract:: The easy picking characteristic, expressed as low pod detachment force (PDF), offers a way to decrease pod damage in bush green beans mechanically harvested for processing and fresh market, and makes hand picking easier and faster. This study was undertaken to examine inheritance in a cross of two green bean...
