Determining novel control methods for cabbage maggot (Delia radicum) in the Pacific Northwest

Creator:: Dugger, Chloe D.
Abstract:: Cabbage maggot, Delia radicum (Diptera: Anthomyiidae) impacts the production of Brassicaceae crops worldwide. The larva feed on the roots of crops causing reductions in yields due to impaired root function and unmarketability of crops. Chemical and cultural management programs are commonly used to control cabbage maggot with varying rates of...

Naphthalene resistance in a house fly strain : its inheritance and characteristics

Creator:: Schafer, James Arnold
Abstract:: A combination of genetical and biochemical methods were utilized in investigating house fly resistance to naphthalene. The inheritance of resistance was determined by crossing a naphthalene resistant strain of Musca domestica L. with a susceptible mutant marker strain. Biochemical comparisons were made on substrains isolated from the progeny of these...

Induction of microsomal oxidases by dieldrin in house flies

Creator:: Walker, Charles Robert
Abstract:: Previous investigations have shown that exposure to DDT results in increased activity in soluble and microsomal enzyme in insects. These responses in DDT-resistant Triatoma infestans nymphs and in adults of DDT-resistant Musca domestica (the common house fly) are accompanied by increased RNA and protein synthesis. The phenomenon has been termed...

Epichloë typhina (fungus) - Botanophila lobata (fly) interaction : an invasive "pollinator" system in its introduced range in western Oregon

Creator:: Kaser, Joseph M.
Abstract:: Epichloë typhina (Ascomycetes: Clavicipitaceae) is an endophytic fungus that infects perennial Pooid grasses and is the causal agent of choke disease. It is endemic to Europe and was inadvertently introduced into orchardgrass seed production fields in western Oregon. Choke disease, which was first recorded in Oregon in 1996, currently infects...

Exploring the biology and monitoring techniques of two economically impactful Chrysobothris species in Oregon hazelnuts

Creator:: Rudolph, Erica
Abstract:: Chrysobothris mali Horn and C. femorata Olivier (Coleoptera : Buprestidae) are two flatheaded wood boring beetle species that have become economically impactful pests in North American high value tree cropping systems. Both species are native to North America, with C. femorata occurring across the continent (Wellso and Manley 2007), whereas...

Biological studies of Eriosoma pyricola with particlar emphasis on morph production

Creator:: Mikesell, Janet May Smith
Abstract:: Various aspects of the biology of the woolly pear aphid Eriosoma pyricola were studied in order to further understand its annual cycle. It was already known that. E. pyricola produces alate sexuparae in response to the onset of dormancy in its secondary host, a pear. This study of E. pyricola...

Population development of Scutigerella immaculata (Newport), in laboratory and greenhouse cultures

Creator:: Ramsey, Henry Lee
Abstract:: Population development of the symphylan, Scutigerella immaculata (Newport), was studied in laboratory cultures. Also symphylan injury to greenhouse plants was investigated. Plastic polyethylene containers partly filled with damp ground hemlock bark were used to culture symphylan in the laboratory. Fresh lettuce food was supplied to the cultures weekly. Factors which...

Plant architectural barriers to feeding site selection by the meadow spittlebug, Philaenus spumarius (L.)

Creator:: Hoffman, George D.
Abstract:: While current theories describing the insect-plant interaction have emphasized the biochemical aspects of the relationship, morphological components can also play a significant role in determining which plants or tissues are susceptible to insect attack. Xylem sap on which spittlebugs feed may lack many of the plant compounds responsible for host...

Nutrient Profile and Nursery Feeding Damage of Halyomorpha halys (Hempitera: Pentatomidae)

Creator:: Skillman, Victoria P.
Abstract:: Halyomorpha halys Stål, brown marmorated stink bug or BMSB, is now present in 43 US states. A native of eastern Asia, this pest can feed on ~200 different plant species damaging bark, leaves, buds, stems, and fruits. Many of these plant species include wild plants, ornamentals, and agricultural crops. BMSB...
