A taxonomic study of Mononchidae (Enoplida : Nemata) inhabiting cultivated areas of Thailand

Creator:: Buangsuwon, Dara Kanhasuwon
Abstract:: Eleven species of Mononchidae Chitwood, 1937 were found among the nematodes separated from 48 soil samples in Thailand and sent to Oregon State University. Six species are newly described and illustrated including Iotonchus bangkokensis, Iotopchus ainostomos, Iotonchus chantabunensis, Iotonchus ravonqensis, fotonchus thai-Iandensis, and Miconchus triodontus. Also reported is a description...

Laboratory studies of bacteriophagous nematodes as potential vectors of insect pathogens

Creator:: Wright, Billie Dean
Abstract:: Three species of bacteriophagous nematodes, Pristionchus lheritieri (Maupas) Paramanov, Pelodera chitwoodi (Bassen) Dougherty and Rhabditis sp. were studied to determine their potential roles as vectors of selected insect pathogens, Bacillus thuringiensis Berliner, Beauveria bassiana (Balsamo) Vuillemin, Metarrhizium anisopliae (Metchnikoff) Sorokin and a nuclear polyhedrosis virus of Trichoplusia ni Hubner. Chlorine...

The biology and pathogenicity of a sheath nematode Hemicycliophora similis Thorne, 1955

Creator:: McKewan, Jeanette Anne
Abstract:: A study, using greenhouse and laboratory experiments, was made of Hemicycliophora similis from Bandon, Oregon to determine: identity and morphometrics, time and development of a life cycle, host plant preferences and optimum environmental conditions for reproduction and pathogenicity. Morphometric investigations revealed discrepancies between the measurements of this nematode species and...

Efficacy of morantel sustained release bolus against gastrointestinal nematodes in first season grazing Holstein calves

Creator:: Syhre, Danny R.
Abstract:: The efficacy of the morantel sustained release bolus (MSRB) in reducing gastrointestinal parasitism in first season grazing calves was evaluated during the summer-fall grazing seasons of 1982 and 1983 in western Oregon. Thirty-eight calves (1982) and 40 calves (1983) were randomly assigned to a control and treatment group each season....

Excretion of viable salmonellae by Salmonella-fed, chlorine-treated nematodes

Creator:: Smerda, Susan Mae
Abstract:: The role of nematodes (Diplogaster lheritieri Maupas 1919) as excretors of pathogenic organisms was studied. Salmonella typhi and Salmonella wichita were fed to nematodes for two days. The nematodes were surface sterilized with free chlorine. The activity of the chlorine was stopped by the addition of sodium thiosulfate followed by...

Transmission of plant pathogenic bacteria and a bacteriophage of Agrobacterium tumefaciens (Smith and Townsend) Conn by a saprozoic nematode, Diplogaster lheriteiri Maupas

Creator:: Chantanao, Aroon
Abstract:: A saprozoic nematode, Diplogaster lheriteiri Maupas 1919, was studied to determine its relationship to the plant pathogenic bacteria, Agrobacterium tumefaciens (Smith and Townsend) Conn., Erwinia amylovora (Burrill) Winslow et al., Erwinia carotovora (Jones) Holland, Pseudomonas phaseolicola (Burk. ) Dows., Xanthomonas campestris (Pam. ) Dows. and to a phage of A....

The Epizootiology of gastrointestinal nematodes of cattle in selected areas of Oregon

Creator:: Rickard, Lora G.
Abstract:: A study was initiated to 1) determine which species of gastrointestinal nematodes are present in cattle in selected areas of Oregon, 2) examine the seasonal abundance of these nematodes as an indicator of periods of transmission and 3) determine at what season developmental inhibition occurs in the major genera of...

Entomopathogenic nematodes for biological control of the Colorado potato beetle, Leptinotarsa decemlineata (Say)

Creator:: Armer, Christine Andrea
Abstract:: The Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), is the most devastating foliage-feeding pest of potatoes in the United States. Potential biological control agents include the nematodes Heterorhabditis marelatus Liu & Berry and Steinernema riobrave Cabanillas, Poinar & Raulston, which provided nearly 100% CPB control in previous laboratory trials. In...

Acari, insecta and nematoda of watershed 10, H. J. Andrews experimental forest

Creator:: Krantz, G. W., Wernz, J. G., Jensen, Harold J. (Harold James), 1921-, Shimabukaro, R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Populations of mites and.nematodes were monitored on Watershed 10, H. J. Andrews Forest. A minimum of 50 families and 60 genera of mites are present, the majority being Cryptostgmata. Population estimates vary from 5000-350,000 per square meter. Nine categories of nematodes are present, most belonging to the saprozoic, dorylaimoid, aquatic...
