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...

Diamondback moth (Plutella xylostella L.) ; toxicological database, resistance monitoring techniques, and intraplant distribution

Creator:: Fongsmut, Anuthep
Abstract:: The diamondback moth (Plutella xylostella L.) is a major pest of crucifer crops worldwide. It is a particularly important problem in Southeast Asia where climatic conditions favor a short generation time and rapid proliferation. In countries such as Thailand, the diamondback moth has apparently become resistant to all classes of...

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...

AppleMgr, a prototype decision aid for apple pest management

Creator:: Haley, Sue
Abstract:: Computer decision aids can help integrate and apply diverse sources of information and expertise to problems of integrated pest management (IPM) in agriculture and forestry. AppleMgr combines a rule-based expert system with databases and spreadsheets in a prototype decision aid intended to be expanded and modified for use by extension...

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...

Biological control of spider mites by the predatory mite Neoseiulus fallacis (Acari: Phytoseiidae) in ornamental nursery systems

Creator:: Pratt, Paul D.
Abstract:: We identified and evaluated a phytoseiid predator as a biological control agent of multiple spider mites pests that occur in ornamental nurseries. When comparing species, Neoseiulus fallacis (Garman) had a wider prey range than Galendromus occidentalis (Nesbitt), a higher probability of overwintering than Neoseiulus califomicus McGregor and was equally or...

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...
