The SELCTV database : the susceptibility of arthropod natural enemies to agricultural pests to pesticides

Creator:: Theiling, Karen M.
Abstract:: Documentation of the side effects of pesticides on arthropod natural enemies has expanded rapidly since the 1950's as part of an increase in non-target side effects literature. Most reviews have been based on empirical analysis of selected literature. The SELCTV database was developed to make a larger information base accessible...

Organotin resistance in tetranychus urticae koch on pear : components and their integration for resistance management

Creator:: Flexner, J. Lindsey
Abstract:: Reversion of resistance to the organotin (OT) acaricide cyhexatin was documented for the twospotted spider mite, Tetranychus urticae (Koch), by laboratory isolation of a field resistant colony. After 22 generations of no selection the colony reverted back to susceptible. Studies were conducted in 1985 and 1986 on susceptible and resistant...

Laboratory Bioassays to Estimate the Lethal and Sublethal Effects of Various Insecticides and Fungicides on Deraeocoris brevis (Uhler) (Hemiptera: Miridae)

Creator:: Amarasekare, K. G. and Shearer, P. W.
Abstract:: This laboratory bioassay focused on lethal and sublethal effects of five insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin) and two fungicide treatments (sulfur and a mixture of copper hydroxide and mancozeb) on the predatory mired bug Deraeocoris brevis (Uhler) (Hemiptera: Miridae) using second instars and adult males and females. Formulated...

Integration of microbial and chemical controls against codling moth, Cydia pomonella (L.) : laboratory and field evaluation

Creator:: Bajwa, Waheed Ibrahim
Abstract:: The feasibility of managing codling moth, Cydia pomonella (L.), with mixtures of Bacillus thuringiensis-based microbial and selected chemical insecticides was studied under laboratory and field conditions. Joint actions (synergism, additivity and antagonism) of these mixtures were determined for both egg and larval stages. Higher rates of microbial control agents (MCAs),...

Identification and development of PCR-based markers linked to eastern filbert blight resistance in hazelnut

Creator:: Davis, Joel W.
Abstract:: Using bulked segregant analysis, five RAPD markers were identified that were linked in coupling to a gene conferring complete resistance to eastern filbert blight caused by Anisogramma anomala (Peck) E. Muller in hazelnut (Corylus avellana L.). Two modified backcross populations were inoculated and scored for resistance to the pathogen and...

Genetics and gene flow of organophosphate resistance in three predatory mites, Amblyseius andersoni Chant, Typhlodromus pyri Scheuten and Metaseiulus occidentalis Nesbitt (Acarina: Phytoseiidae), in Oregon

Creator:: Dunley, John E.
Abstract:: Genetics, gene flow, and distribution of pesticide resistance traits were examined for organophosphate (OP) resistance in three beneficial phytoseiid mites. Levels and genetics of OP resistance in Amblyseius andersoni were examined first. Laboratory strains from Italy and Oregon, USA, were compared in susceptibility to insecticides used in western Oregon fruit...

Genetic variability in the eastern filbert blight pathosystem

Creator:: Osterbauer, Nancy K.
Abstract:: The heritability of resistance to eastern filbert blight, caused by Anisogramma anomala, in European hazelnut (Corylus avellana) was evaluated in the progeny of seven cultivars crossed in 12 combinations. Progeny produced by crossing 'VR6-28' with three susceptible cultivars segregated 1:1 for complete resistance to eastern filbert blight. Histograms of disease...

Genetic resistance to eastern filbert blight

Creator:: Coyne, Clarice Jean
Abstract:: Eastern filbert blight, caused by Anisogramma anomala (Peck) E. Muller, is a serious threat to hazelnut (Corylus avellana L.) production. Resistant cultivars offer the best control. Screening systems were needed to reliably identify disease, particularly in immune progeny derived from 'Gasaway'. An indirect enzyme-linked immunosorbant assay (ELISA) was developed using...

Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...
