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....
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...
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.
