Biology, ecology and management of Scaptomyza apicalis Hardy (Diptera : Drosophilidae) on meadowfoam, Limnanthes alba benth in western Oregon

Creator:: Panasahatham, Sarote
Abstract:: Biology of Scaptomyza apicalis Hardy (Diptera: Drosophilidae) was studied in relation to its host, meadowfoam, Limnanthes alba, a recent oil seed crop grown in the Willamette Valley, Oregon. Populations of flies and larvae were monitored weekly over three consecutive crop-years beginning in 1996. Yellow sticky traps gave relative population estimates...

Nutritional ecology of millipedes in Pacific Northwest conifer forests

Creator:: Baumeister, Nancy C.
Abstract:: Comminution of forest leaf litter by millipedes affects litter decomposition and nutrient cycling. The millipede Harpaphe haydeniana Wood (Polydesmida: Xystodesmidae) is common in low to mid-elevation forests on the Pacific Coast of North America. In a series of experiments, the suitability of broadleaf and conifer tree litters for growth of...

The ecology of Chironomidae associated with stabilization lagoons

Creator:: Sturgess, Brian Thomas
Abstract:: Chironomidae occurring in stabilization lagoons were studied from 1964 to 1966 in Oregon. Observations of other insects and their impact on the lagoon environment are included. Quantitative data were obtained from two lagoons near Corvallis and qualitative observations from preliminary work on two other lagoons are reported. The objectives of...

The ecology and production dynamics of four black fly species (Diptera:simuliidae) in western Oregon streams

Creator:: Speir, Jon A.
Abstract:: Ecological and production studies of Prosimulium caudatum Shewell, P. dicum Dyar and Shannon, Simulium arcticum Malloch and S. canadense Hearle (Diptera: Simuliidae) were made in 1971 and 1972 in three streams near Corvallis, Oregon. The purpose of the study was to characterize the biology and population dynamics of larvae, and...

Ecology of mites on pomaceous fruit trees and related wild hosts in Hood River Valley

Creator:: Jorgensen, Clive Darrel
Abstract:: The ecological interrelationships of mites occurring in and near the Hood River Valley, Oregon, pome fruit orchards were investigated to determine the possibility of an integrated control program using the species already present. Survey sampling methods were used to study mites on wild hosts (Crataegus douglasii Lindl., Crataegus columbiana Howell,...

Foraging ecology of pollinators in the early stages of secondary succession in the western hemlock (Tsuga heteropohylla (Raf.) Sarg.) zone of the Oregon Coast Range

Creator:: Burikam, Intawat
Abstract:: The early stages of secondary succession of the McDonald and Paul Dunn State Forests, Corvallis, Oregon, were grouped into three stages; herb, herb-shrub, and shrub, based on vegetation types. Flowers of herbaceous species and residual shrubs dominated in the early years after clear-cutting. Woody plants became increasing abundant in 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...
