Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Creator:: Madson, Stephanie Lee
Abstract:: The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to...

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...

Regional population dynamics of Argyrotaenia citrana in Northwest caneberry : phenology, overwintering survivorship, and movement as measured by pheromone traps and larval sampling

Creator:: Knight, Alan Lee
Abstract:: Developmental requirements were determined for both larva and pupa as 503 and 176 degree-days (dd) above a lower threshold of 5°C. Adult emergence occurred from 300 to 700 dd accumulated from January 1st. Cumulative male emergence preceded female's by 50 - 80 dd. A PETE phenology model modified to include...

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...

Biological control of spider mites (Acari: Tetranychidae) on grape emphasizing regional aspects

Creator:: Prischmann, Deirdre A.
Abstract:: 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...

Evaluating benthic macroinvertebrates as bio-indicators of freshwater habitat quality in an eastern Oregon agro-ecosystem

Creator:: Scherr, Melissa A.
Abstract:: The effect of anthropogenic disturbance on river systems is gaining attention, and concerns about the state of freshwater natural resources are increasing globally, as are efforts to restore habitat that has been degraded by disturbance. In rivers, non-point source pollution affects the physical characteristics of the habitat and the endemic...

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...
