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

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...
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....
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.

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...
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....
