Although a 35% population increase is projected by 2050. Significant improvements are consequently necessary in terms of resource use efficiency. In moving crop yields towards an efficiency frontier, optimal pest and disease management will be essential, especially as the proportional production of some commodities steadily shifts. With this in mind, it is essential that the full spectrums of crop production limitations are considered appropriately, including the often overlooked nematode constraints about half of all nematode species are marine nematodes, 25% are free-living, soil inhabiting nematodes, I5% are animal and human parasites and l0% are plant parasites. Today, even with modern technology, 5-l0% of crop production is lost due to nematodes in developed countries. So, the aim of this work was to review some agricultural nematodes genera, species they contain and their management methods. In this review work the species, feeding habit, morphology, host and symptoms they show on the effected plant and management of eleven nematode genera was reviewed.

Surveys were conducted in Idaho, USA during the 2000-2006 cropping seasons to study the occurrence, population density, host association and distribution of plant-parasitic nematodes associated with major crops, grasses and weeds. Eighty-four species and 43 genera of plant-parasitic nematodes were recorded in soil samples from 29 crops in 20 counties in Idaho. Among them, 36 species are new records in this region. The highest number of species belonged to the genus Pratylenchus; P. neglectus was the predominant species among all species of the identified genera. Among the endoparasitic nematodes, the highest percentage of occurrence was Pratylenchus (29.7) followed by Meloidogyne (4.4) and Heterodera (3.4). Among the ectoparasitic nematodes, Helicotylenchus was predominant (8.3) followed by Mesocriconema (5.0) and Tylenchorhynchus (4.8). Keywords.

Nemalol., 1998,21 (6), 655-666 PCR-RFLP and sequencing analysis of ribosomal DNA of Bursaphelenchus nematodes related to pine wilt disease(l) Hideaki IvVAHORI, Kaku TSUDA, Natsumi KANZAKl, Katsura IZUI and Kazuyoshi FUTAI Cmduate School ofAgriculture, Kyoto University, Sakyo-ku, Kyoto 606-8502, Japan. Accepted for publication 23 December 1997. Summary -A polymerase chain reaction - restriction fragment polymorphism (PCR-RFLP) analysis was used for the discri­ mination of isolates of Bursaphelenchus nematode. The isolares of B. xylophilus examined originared from Japan, the United Stares, China, and Canada and the B. mucronatus isolates from Japan, China, and France. Ribosomal DNA containing the 5.8S gene, the internai transcribed spacer region 1 and 2, and partial regions of 18S and 28S gene were amplified by PCR. Digestion of the amplified products of each nematode isolate with twelve restriction endonucleases and examination of resulting RFLP data by cluster analysis revealed a significant gap between B. xylophllus and B. mucronatus. Among the B. xylophilus isolares examined, Japanese pathogenic, Chinese and US isolates were ail identical, whereas Japanese non-pathogenic isolares were slightly distinct and Canadian isolates formed a separate cluster. Among the B. mucronalUS isolates, two Japanese isolares were very similar to each other and another Japanèse and one Chinese isolare were identical to each other. The DNA sequence data revealed 98 differences (nucleotide substitutions or gaps) in 884 bp investigated between B. xylophilus isolare and B. mucronmus isolate; DNA sequence data of Aphelenchus avenae and Aphelenchoides fragariae differed not only from those of Bursaphelenchus nematodes, but also from each other.

ZooKeys 574: 43–55. doi: 10.3897/zookeys.574.7222 Abstract The dataset of free-living marine nematodes of San Antonio Bay is based on sediment samples collected in February 2009 during doctoral theses funded by CONICET grants. A total of 36 samples has been taken at three locations in the San Antonio Bay, Santa Cruz Province, Argentina on the coastal littoral at three tidal levels. This presents a unique and important collection for benthic biodiversity assessment of Patagonian nematodes as this area remains one of the least known regions.
