Transmission variation and loss of aphid transmissibility of bean yellow mosaic virus

Creator:: Kamm, James A.
Abstract:: Several bean yellow mosaic virus (BYMV) strains, presumably not transmissible by aphids, were studied to determine the biological and environmental conditions which would possibly result in aphid transmission of these strains. Investigations were made to study the effect of different aphid rearing conditions on the transmission frequency of BYMV. Also,...

Reduction of salmonid predators by chemical treatment

Creator:: Reeher, James A., Hewkin, James A., West, Duane C., and Oregon. State Game Commission. Fishery Division
Abstract:: The upper drainage of the John Day River system produces summer steelhead and spring chinook salmon. The fish are generally confined to the main stem and its tributaries above Prairie City.

Habitat improvement to enhance anadromous fish production [Tex Creek]

Creator:: West, Duane C., Reeher, James A., Hewkin, James A., and Oregon. State Game Commission. Fishery Division
Abstract:: The project objectives were to determine the possibility of raising the subterranean water in adequate amounts by installation of an underground weir; to determine what type of structure would be most feasible; and to formulate a biological evaluation program if the first two objectives were accomplished. Tex Creek, tributary to...
