Résumé :

The population densities of four species of root-lesion nematodes (Pratylenchus) were examined in two cultivars of oat (Avena sativa L.) grown in greenhouse pots. The cultivar Saia harbored fewer P. neglectus and P. penetrans than the cultivar OAC Woodstock, while both cultivars were similar hosts for P. sensillatus. Pratylenchus crenatus did not develop in either cultivar.Key words: Oat, population density, Pratylenchus crenatus, Pratylenchus neglectus, Pratylenchus penetrans, Pratylenchus sensillatus

Root-lesion nematode species rank third only to root-knot and cyst nematodes as having the greatest economic impact on crops worldwide. A survey of plant-parasitic nematodes associated with decaying raspberries (Rubus sp.) in northern Italy revealed that root-lesion nematodes were the most frequently occurring species among other phytonematodes. Several Pratylenchus species have been associated with Rubus sp. in Canada (Quebec, British Columbia) and USA (North Carolina, Maryland, New Jersey) including P. penetrans and P. crenatus.

Résumé :

Root-lesion nematodes (Pratylenchus spp.) of the genus Pratylenchus Filipjev, 1936, are among the most important nematode pests on soybean (Glycine max (L.) Merr.), along with soybean cyst and root-knot nematodes. In May 2015 and 2016, a total of six soil samples were collected from a soybean field in Walcott, Richland County, ND and submitted to the Mycology and Nematology Genetic Diversity and Biology Laboratory (MNGDBL), USDA, ARS, MD for analysis. Later, in 2019, additional nematodes recovered from a greenhouse culture on soybean originally from the same field were submitted for further an

AbstractThe distribution and diversity of Pratylenchus species associated with Ammophila arenaria was investigated in its natural range of distribution. Twelve localities with vigorous stands of A. arenaria along the European Atlantic and Mediterranean coasts were sampled. The populations were identified based on morphology and morphometrics, and further characterised based on sequences of the rDNA D2D3 region. Pratylenchus spp. were present in all of the sampled sites. A total of 19 populations were detected belonging to Pratylenchus dunensis, P. brzeskii, P. pratensis or P. penetrans. Pratyl

Résumé :

Due to Israel’s successful agricultural production and diverse climatic conditions, plant-parasitic nematodes are flourishing. The occurrence of new, previously unidentified species in Israel or of suggested new species worldwide is a consequence of the continuous withdrawal of efficient nematicides. Among plant-parasitic nematodes, migratory endoparasitic species of the genus Pratylenchus are widely distributed in vegetable and crop fields in Israel and are associated with major reductions in quality and yield. This review focuses on the occurrence, distribution, diagnosis, pathogenicity, and

Plant parasitic nematodes (PPN) are important pests of corn (Zea mays L.) Globally, while corn production has recently expanded in Sri Lanka. The population abundance, distribution, and pathological effects of nematodes that adversely affect corn production in Sri Lanka are poorly understood. This study was conducted to identify the prevalence of major PPN genera, population abundance, and their reproduction associated with corn fields in the Anuradhapura district. Over 92% of the corn fields were positive for PPN from the fields sampled in February 2021. Major PPN genera identified were Praty

Plant-parasitic nematodes devastate a wide range of plant species across the world including many economically important crops such as coffee. Determining the mechanisms that underpin nematode entry and parasitism of the root is of great interest for the design of control strategies. The first aspect of crop protection is to accurately and reliably diagnose the nematode species of concern. A molecular pipeline is described in this thesis that utilises PCR to rapidly detect and quantify the major Meloidogyne and Pratylenchus nematode species that are capable of parasitising coffee.

Résumé :

Potatoes is the fourth important food crop worldwide after maize, wheat, and rice and are grown in more than 100 countries worldwide under temperate, subtropical and tropical conditions, however, they are considered as cool temperature crop. Potato is one of the most important food crops in Georgia and potato growing has always been the subject of great importance for settlement of food supply problems in country. Potato crops are severely affected by approximately forty soil borne diseases worldwide including those caused by soil inhabiting fungi, bacteria and nematodes. Plant-parasitic nemat

Résumé :

Two experiments were carried out to verify the susceptibility of olive plantlets of the Xylella fastidiosa - resistant cultivar Favolosa to the root-knot nematode Meloidogyne javanica and the root lesion nematode Pratylenchus vulnus. In the first experiment the relationship between the nematode population density and the olive plants growth was assessed. Plant growth parameters, main shoot length and diameter and number of nodes, were analysed by the SeinFit program in order to calculate the tolerance limit (T) to the nematode attack and the minimum relative per cent growth (m) of the plants.

Résumé :

Abstract Soil-borne plant-parasitic nematodes are microscopic, eellike roundworms. The root-knot nematodes (Meloidogyne spp.) and root-lesion nematodes (Pratylenchus vulnus) are among the most damaging in California, which are difficult to control and can spread easily in soil on tools, boots, and infested plants. Root-knot nematodes can attack many different crops, including nut and fruit trees, usually cause unusual swellings, called galls, on affected plants’ roots. It is not easy to recognize the infestations of these nematodes. For instance, researchers need to dig up walnut trees with sy

Résumé :

Verticillium dahliae is an economically important pathogen causing vascular wilt on over 160 plant species. In North America, potato early dying is a significant disease of potato, especially in the midwest and Pacific northwest states. This disease is caused by the fungus Verticillium dahliae and in some cases involves a synergistic interaction with root-lesion nematodes, primarily Pratylenchus penetrans. In Israel, Verticillium wilt occurs in many regions and inflicts serious losses in potato, cotton, and other crops. Objectives of this project were to establish a large collection of isolate
