Plant colonization of gopher mounds in adjacent pasture and prairie communities

Creator:: Macdonald, Catherine A.
Abstract:: I used field experiments to study how plants in two grassland communities colonized soil mounds made by the Camas pocket gopher, Thomomys bulbivorus (Richardson). I identified potential mound colonizers in each source of colonization (buried propagule bank, seed rain, and established vegetation) and then measured species specific rates of colonization...

Transmission efficiency and life table parameters of western flower thrips, Frankliniella occidentalis (Pergande) exposed to tomato spotted wilt virus-impatiens serotype

Creator:: Sether, Diane M.
Abstract:: Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint, initially observed in a research greenhouse (Corvallis, OR), included stunting and downward curling of leaves accompanied by bronzing, and occasionally tip necrosis. Young leaves appeared either symptomless, deformed, or...

Within and between plant dispersal and distributions of adult females and immatures of Neoseiulus californicus and N. fallacis (Acari: Phytoseiidae) in bean and apple plant systems

Creator:: Pratt, Paul D. (Paul David), 1970-
Abstract:: Intra- and interplant movement and dispersal of the predator mites Neoseiulus californicus (McGregor) and Neoseiulus fallacis (Garman) were studied on both lima bean (Phaseolus lunatus L.) and apple (Malus pumila Miller) branch plant systems that were seeded with excess numbers of the spider mite Tetranychus urticae Koch. Individuals of either...

Ambulatory and aerial dispersal among specialist and generalist phytoseiid mites

Creator:: Jung, Chuleui
Abstract:: Specialist and generalist phytoseiid mites are widely used for biological control of spider mites. Understanding dispersal attributes of these mites is important to implementing more stable, cost-efficient integrated pest management. In this regard, we studied dispersal of phytoseiid mites from a local ambulatory phase of movement within a prey patch...

Ecological relationships among western Ephemerellidae : growth, life cycles, food habits, and habitat relationships

Creator:: Hawkins, Charles Patrick
Abstract:: The purpose of this study was to describe the life cycles, feeding ecology, and habitat use of western species in the mayfly family Ephemerellidae. Data were used to compare the ecological relationships and strategies among species and to examine patterns of adaptive radiation within the family. Data were further used...

Distribution of Oligonychus (Oligonychus) ununguis (Jacobi) (Acari: Tetranychidae) and predator mite species (Acair: Phytoseiidae) on field-grown Douglas-fir (Pseudotsuga menziesii [Mirb] Franco) Christmas trees

Creator:: Calkin, James D.
Abstract:: The shake and wash technique (samples placed in a jar with alcohol added and shaken to remove the mites) was effective in removing 100% of the predator mites, and adult spruce spider mites from Douglas-fir foliage and 98% of the spruce spider mite nymphs. Eighty-eight percent of the spruce spider...

Sound production in Leperisinus oregonous Blackman and L. californicus Swaine (Coleoptera:Scolytidae)

Creator:: Vernoff, Suellen
Abstract:: Both Leperisinus oregonus and L. californicus are bark beetle species which emerge from Fraxinus latifolia brood logs as sexually immature adults and disperse to living ash. Occasional field observations suggest that, for overwintering and maturation feeding, L. oregonus enter trunks and branches, whereas L.; californicus enter twig crotches, buds and...
