<p>Aphelenchoides besseyi is a seed-borne nematode that causes white-tip disease in rice. Yield losses due to this infection reach 30-50% various countries. This research aimed investigate the effectiveness of consortium rhizobacteria and endophytic bacteria controlling white tip while promoting growth rice seeds infected by A. besseyi. The experiments conducted were bacterial compatibili...

Spicules of 9 Meloidogyne, 2 Heterodera, 3 Globodera, and 12 other plant-parasitic, insect-parasitic, and free-living nematodes were excised and examined using scanning electron microscopy (SEM). Gubernacula of some of the species were also excised, and their structure was determined. The two spicules of all species examined were symmetrically identical in morphology. The spicule typically cons...

Fatty acid profiles of fungal-feeding nematodes, Aphelenchus avenae and Aphelenchoides composticola, and selected fungi were determined in microcosm cultures of agar, broth, or sand amended with organic matter. Fatty acids of A. avenae and A. composticola included 16:0 18:0, 18:1omega7, 18:1omega9, 18:2, 20:0, 20:1, 20:2, 20:3 and 20:4 phospholipid fatty acids (PLFAs) and neutral lipid fatty ac...

The foliar nematode Aphelenchoides besseyi causes white tip disease in rice (Oryza sativa L.) and floral malady in tuberose (Polianthes tuberosa L.). This nematode is widely distributed in the rice fields of many states of India, including West Bengal (WB), Andhra Pradesh (AP), Madhya Pradesh (MP) and Gujarat (GT). In order to generate information on intraspecific variations of A. besseyi as we...

Summary At the time of description, morphology Ptychaphelenchus eucalypticola Hodda, 2009 indicated it could be assigned to either Aphelenchoididae Skarbilovich, 1947 (Paramonov, 1953) or Parasitaphelenchidae Ruehm, 1956 (Siddiqi, 1980) within Aphelenchoidoidea 1980). Although P. was, tentatively, and remains Aphelenchoididae, its relationships with other aphelenchoids have not been reassessed,...

Saltwater intrusion is a potential risk damaging crop diversity and productivity due to degraded soil physicochemical properties. However, little known about how salinity affects the structure function of nematodes community in intensive rice cultivated area. This study aimed (1) assess impacts saltwater on nematode alluvial acid sulfate soils; (2) evaluate its relation with conditions. reduced...
