Temperature-dependent development of strawberry root weevil Otiorhynchus ovatus (L.)

Creator:: Umble, Jon R.
Abstract:: The temperature-dependent development of pupae and adults of strawberry root weevil (SRW) Otiorhynchus ovatus (L.) was studied in strawberry (Fragaria x ananassa Duch. var. 'Totem'). The development of pupae and adults was investigated at constant temperatures from 3-33°C at 3°C intervals. Major emphasis was on the development of a weighted...

Soil arthropods in the Central Cascades : slash burning effects and biology of some species

Creator:: Estrada-Venegas, Edith G
Abstract:: Despite the recognized role of soil arthropod fauna on nutrient cycling and decomposition processes, many aspects of the effects of sylvicultural methods in forest ecosystems upon their biology remain poorly understood. The long term effects of prescribed fires on soil arthropods in forest ecosystems in the Pacific Northwest have never...

Effects of stream restoration on macroinvertebrate communities in an Oregon Coast Range system

Creator:: Christensen, M. Jo
Abstract:: Stream-restoration projects are usually designed to improve habitat quality for fishes. These projects manipulate flow patterns, substrate distribution, and amount and placement of large woody debris. Consequently, they also affect the size and composition of the aquatic macroinvertebrate community. This research evaluates two types of fish habitat restoration: off-channel structures...

Aspects of the bionomics of the parasitic honey bee brood mite, Varroa jacobsoni Oudemans

Creator:: Principal de D'Aubeterre, Judith
Abstract:: Aspects concerning the bionomics of the parasitic honey bee brood mite, Varroa jacobsoni Oudemans were investigated. Mite mortality is great during the winter season when the host colony is not rearing brood, appearing to be independent of the mortality of its host. In winter period, no significant association between the...

Abundance and community composition of arboreal spiders : the relative importance of habitat structure, prey availability and competition

Creator:: Halaj, Juraj
Abstract:: This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed...

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...

Effects of wood species and prior fungal exposure on the feeding habits of the dampwood termite Zootermopsis angusticollis

Creator:: Mankowski, Mark Edward
Abstract:: The effects of natural preconditioning (source wood), wood species, and previous exposure of wood to two types of fungi on the feeding rates and protozoa survival in the Pacific dampwood termite Zootermopsis angusticollis (Isoptera: Termospidae) were examined under laboratory conditions. Termites were exposed to four wood species that had been...
