Status, distribution and seasonal variation of filbert aphid resistance to selected insecticides in the Willamette Valley, Oregon

Creator:: Katundu, Juma
Abstract:: Levels of resistance to six selected insecticides of eleven field populations of the filbert aphid Mvzocallis coryli (Goetze) were determined by using the leaf-dip residue technique. Test insecticides included compounds widely used in commercial filbert orchards, namely, carbaryl, diazinon, endosulfan, phosalone, fenvalerate and oxydemetonmethyl. Aphid samples were collected within a...

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...

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...

Sampling methods, biology and management of the mint flea beetle in central Oregon peppermint

Creator:: Morris, Mark A.
Abstract:: Sampling techniques were evaluated to quantify immature mint flea beetle (MFB), Longitrsus waterhousei Kutschera (Coleoptera: Chrysomelidae), on peppermint (Mentha piperita L.), in central Oregon. During the study period, 1985-1988, soil samples of 350 cm³ were effective for collecting immature MFB. Sifting soil samples through screens was effective for estimating post-feeding...

Biology and management of a mushroom-infesting sciarid fly (Diptera: Sciaridae) in relation to room-to-room dispersal

Creator:: Mehelis, Christopher N.
Abstract:: The purpose of this research is two fold. First to improve pest management of the sciarid fly (Diptera: Sciaridae) by better defining its relation to mushroom production. Secondly, to explore some of the factors and aspects of the biology of the fly which may increase room to room dispersal rates...
