0An assessment of the oviposition behavior of spotted-wing drosophila (Drosophila suzukii) in the presence of a novel management tool in Pinot noir grapes

Creator:: Blood, Rachel A.
Abstract:: Spotted-wing drosophila (SWD, Drosophila suzukii) is an invasive fruit fly species native of Southeast Asia. In vineyards, SWD lays eggs in damaged and intact fruit of the most soft-skinned varieties, and feeds on damaged fruits during the harvest period. Feeding and oviposition activities increase the likelihood of vectoring spoilage bacteria,...

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....

Evaluating Leucopis species (Diptera: Chamaemyiidae) from the Pacific Northwest as potential biological control agents of the hemlock woolly adelgid (Hemiptera: Adelgidae)

Creator:: Grubin, Sarah M.
Abstract:: Hemlock woolly adelgid, Adelges tsugae Annand, is a destructive introduced pest of hemlock trees in eastern North America, and management has focused on the use of natural enemies through classical biological control. Two species of chamaemyiid flies, Leucopis argenticollis Zetterstedt and Leucopis atrifacies (Aldrich) have been collected previously from western...

The Role of Diurnal Light, Temperature, and Forced Egg Retention on Spotted Wing Drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae) Survival and Ovipositional Rates

Creator:: York, Riki M.
Abstract:: Drosophila suzukii (Diptera: Drosophilidae) is a devastating pest that attacks thin-skinned stone and small fruit in all major production regions of the United States and worldwide. D. suzukii first appeared in the United States in 2008 and is believed to be native to Southeast Asia. This vinegar fly has a...

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...

Enhancing pest mite biological control by Typhlodromus pyri (Acari: Phytoseiidae) in Pacific Northwest vineyards

Creator:: Gadino, Angela Noelle
Abstract:: The predatory mite Typhlodromus pyri (Acari: Phytoseiidae) is the predominant species in cool climate Pacific Northwest vineyards and a principal predator of pest mites including the grapevine rust mite Calepitrimerus vitis (Acari: Eriophyidae). In recent years vineyards have been experiencing C. vitis population outbreaks leading to increased economic damage from...

The Impact of Temperature on Halyomorpha halys (Hemiptera: Pentatomidae) Life Table Parameters and Feeding Pressure

Creator:: Maslen, Erika A.
Abstract:: Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive insect pest that has become established and problematic in the Pacific Northwest. Known colloquially as the brown marmorated stink bug (BMSB), H. halys causes direct damage through feeding activity on a wide range of agronomic and horticultural crops. The objectives of this...

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...

Alternative Controls for Stephanitis pyrioides in the Pacific Northwest.

Creator:: Graham, Katerina V.
Abstract:: The azalea lace bug (Stephanitis pyrioides Scott) is a global pest of rhododendrons and azaleas (Rhododendron spp.). It is originally from Asia, has been established in the eastern U.S. for the past century, and was recently detected in the Pacific Northwest in 2008-2009. Stephanitis pyrioides feeds on the underside of...

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...
