Plant-Parasitic Nematodes and Their Management: a Review
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by International Institute for Science, Technology and Education (IISTE): E-Journals Journal of Biology, Agriculture and Healthcare www.iiste.org ISSN 2224-3208 (Paper) ISSN 2225-093X (Online) Vol.8, No.1, 2018 Plant-Parasitic Nematodes and Their Management: A Review Misgana Mitiku Department of Plant Pathology, Southern Agricultural Research Institute, Jinka, Agricultural Research Center, Jinka, Ethiopia Abstract Nowhere will the need to sustainably increase agricultural productivity in line with increasing demand be more pertinent than in resource poor areas of the world, especially Africa, where populations are most rapidly expanding. 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. -
Summary Paratrichodorus Minor Is a Highly Polyphagous Plant Pest, Generally Found in Tropical Or Subtropical Soils
CSL Pest Risk Analysis for Paratrichodorus minor copyright CSL, 2008 CSL PEST RISK ANALYSIS FOR Paratrichodorus minor Abstract/ Summary Paratrichodorus minor is a highly polyphagous plant pest, generally found in tropical or subtropical soils. It has entered the UK in growing media associated with palm trees and is most likely to establish on ornamental plants grown under protection. There is a moderate likelihood of the pest establishing outdoors in the UK through the planting of imported plants in gardens or amenity areas. However there is a low likelihood of the nematode spreading from such areas to commercial food crops, to which it presents a small risk of economic impact. P. minor is known to vector the Tobacco rattle virus (TRV), which affects potatoes, possibly strains that are not already present in the UK, but the risk of the nematode entering in association with seed potatoes is low. Overall the risk of P. minor to the UK is rated as low. STAGE 1: PRA INITIATION 1. What is the name of the pest?

Xiphinema Japonicum N. Sp. (Nematoda: Longidorinae) from the Rhizosphere of Japanese Podocarpus Macrophyllus (Thunb.), a Cryptic
Journal of Nematology 49(4):404–417. 2017. Ó The Society of Nematologists 2017. Xiphinema japonicum n. sp. (Nematoda: Longidorinae) from the Rhizosphere of Japanese Podocarpus macrophyllus (Thunb.), a Cryptic Species Related to Xiphinema bakeri Williams, 1961 1 2 3 4 5 LIRONG ZHAO, WEIMIN YE, MUNAWAR MARIA, MAJID PEDRAM, AND JIANFENG GU Abstract: Xiphinema japonicum n. sp., isolated in Ningbo, China, from the rhizosphere of Podocarpus macrophyllus (Thunb.) imported from Japan is described. The new species belongs to Xiphinema non-americanum group 7 and is characterized by medium body length (3.0–3.7 mm), total stylet length 190–201 mm, vulva located anteriorly (V = 30.5%–35.3%), two equally developed female genital branches without uterine differentiation (no Z or pseudo-Z organ and/or spines in the uteri), short tail, convex-conoid with subdigitate peg in terminus, and absence of males. The species has four juvenile developmental stages (J1 was not found). The polytomous identification codes of the new species are (codes in parentheses are exceptions) A4-B4-C4-D5(4)-E2(3)-F3(4)-G2(3)- H2-I3-J4-K?-L1. Morphologically, the new species is mainly characterized by combination of the codes C4 and E2(3), making the species unique and different from other species in the genus. It is most similar to the North American species Xiphinema bakeri, herein considered as its cryptic species by the nature of high morphological similarity, but with significant differences in DNA sequences in nearly full length 18S, ITS1, 28S D2/D3, and cytochrome c oxidase subunit 1 sequences. -

Box 7062, Kampala Uganda Section Objectives Going through this section will enrich you with skill to be able to: diagnose nematode problems in the field considering all aspects involved in sampling, extraction and counting of nematodes from soil and plant parts, make permanent mounts, set up and maintain nematode cultures, design experimental set-ups for tests with nematodes Section Content sampling and quantification of nematodes extraction methods for plant-parasitic nematodes, free-living nematodes from soil and plant parts mounting of nematodes, drawing and measuring of nematodes, preparation of nematode inoculum and culturing nematodes, set-up of tests for research with plant-parasitic nematodes, A. Nematode sampling Unlike some pests and diseases, nematodes cannot be monitored by observation in the field. Nematodes must be extracted for microscopic examination in the laboratory. Nematodes can be collected by sampling soil and plant materials. There is no problem in finding nematodes, but getting the species and numbers you want may be trickier. In general, natural and undisturbed habitats will yield greater diversity and more slow-growing nematode species, while temporary and/or disturbed habitats will yield fewer and fast- multiplying species. Sampling considerations Getting nematodes in a sample that truly represent the underlying population at a given time requires due attention to sample size and depth, time and pattern of sampling, and handling and storage of samples. -
