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...

Bionomics of the hop cyst nematode, Heterodera humuli Filipjev, 1934 (Nematoda : Heteroderidae)

Creator:: Sen, Arun Kumar
Abstract:: The hop cyst nematode, Heterodera humuli Filipjev, 1934 was first reported from Europe in 1894, however, very little is known with respect to the biology and economic importance of this pest. Abundant material from Oregon hop yards provided an excellent opportunity to add additional details concerning the bionomics of this...

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....

Studies of northern root-knot nematode (Meloidogyne hapla, Chitwood 1949) biotypes and some factors associated with their biology and pathogenicity

Creator:: Ogbuji, Rufus Omez, 1941-
Abstract:: Root-knot nematodes were among the earliest plant-parasitic nematodes to be recognized. Before 1949, they were considered as the one species Heterodera marioni (Cornu 1887) Goodey 1932. In 1949 Chitwood completed a taxonomic study of the root-knot nematodes and placed them in a separate genus Meloidogyne. Economically they are one of...

Interrelationships of Meloidogyne hapla Chitwood, 1949 with Heterodera schachtii Schmidt, 1871 on Beta vulgaris L.

Creator:: Jatala, Parviz
Abstract:: Self-interactions (effects of reinoculation with the same nematode) in Meloidogyne hapla and Heterodera schachtii on Beta vulpris at different levels of inocula with various population combinations were studied. In M. hapla, the only significant increase of galls was noted in treatments when 250+250 larvae were inoculated at 10-day intervals. Longevity...

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...
