Management of variegated cutworm in peppermint

Creator:: Coop, Leonard Bryan
Abstract:: A pest management program for variegated cutworm (VC), Peridroma saucia (Hubner), in Oregon peppermint was developed based on studies of pheromone trapping, sampling methods, and economic thresholds. Pheromone traps effectively trapped VC males and were used to reflect development and oviposition trends. Trap height was linearly correlated to moth catch...

Decomposition of Basamid in Douglas-fir heartwood

Creator:: Forsyth, Paul Griffin
Abstract:: Basamid^R (3,5-dimethy1-1,3,5,2H-tetrahydrothiadiazine- 2-thione) is a crystalline powder used as a soil sterilant. This fumigant acts in soil by decomposing to methylisothiocyanate (MITC), the primary active ingredient, as well as hydrogen sulfide, methylamine, and formaldehyde. In wood, Basamid decomposes too slowly to be efficacious against decay fungi unless amended with various...

Studies on the etiology and epidemiology of bull's eye rot of pears

Creator:: Henriquez, Jose Luis, 1961-
Abstract:: The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Classical biological control of the filbert aphid, Myzocallis coryli (Goetze) (Homoptera:Aphididae) in western Oregon

Creator:: Messing, Russell H.
Abstract:: A classical biological control project was undertaken against the filbert aphid, Myzocallis coryli (Goetze), in western Oregon. Hazelnut orchards in Spain, France, and Italy were searched for natural enemies of the aphid, and a parasitic wasp, Trioxys pallidus Haliday, was imported, quarantined, mass-reared, and released in Oregon orchards. The wasp...

Management of powder-post beetles, Dinoderus minutus F. in freshly cut bamboo

Creator:: Garcia, Carlos Manalo
Abstract:: The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and ftmgi associated with beetles were investigated. Finally, the...

Plant hormone-induced defense responses against Botrytis cinerea

Creator:: Akagi, Aya
Abstract:: Several plant hormones, including ethylene and jasmonates, are known to mediate responses against biotic and abiotic stress. The first and second objectives of this thesis were (i) to elucidate the role of ethylene in defense responses against Botrytis cinerea and specifically (ii) to determine the potential contribution of ethylene response...

The potential of endemic natural enemies to suppress pear psylla, Cacopsylla pyricola Förster, in the Hood River Valley, Oregon

Creator:: Booth, Steven R.
Abstract:: This thesis addressed the potential of endemic predaceous and parasitic arthropods of the Hood River Valley, Oregon to suppress the pear psylla, Cacopsylla pyricola F8rster. Natural enemies adequately suppressed psylla in three of seven unsprayed orchards of differing vegetational settings, orchard age, and size. Relatively few psylla natural enemies dispersed...

Biosynthesis of blasticidin S : mechanistic and stereochemical investigations

Creator:: Prabhakaran, P. C.
Abstract:: Feeding of [3-¹³C, 2-¹⁵N]arginine, 38a, unequivocally established that the β- arginine moiety of blasticidin S, 1, was formed from α-arginine by an intramolecular migration of the α-amino group to the β- position. Further feedings using chirally deuteriated arginines 38e and 38f revealed that the aminomutase process occurred with inversion of...
