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 phylogeny of all Pratylenchus species recorded over the last few decades on different crops grown throughout Israel—covering early information from nematologists to recent reports involving the use of molecular phylogenetic methodologies. We explore the accepted distinction between Pratylenchus thornei and Pratylenchus mediterraneus isolated from Israel’s northern Negev region, and address the confusion concerning the findings related to these Pratylenchus species. Our recent sampling from the northern Negev revealed the occurrence of both P. thornei and P. mediterraneus on the basis of molecular identification, indicating P. mediterraneus as a sister species of P. thornei and their potential occurrence in a mixed infection. Finally, the efficiencies of common control measures taken to reduce Pratylenchus’ devastating damage in protected crops and field crops is discussed.

Summary The distribution and community structure of plant-parasitic nematodes associated with betel (Piper betle) vine and their relationship with soil chemical properties were investigated in four major growing regions of West Bengal, India. Ordinary kriging method was applied to infer the patterns of spatial distribution of major plant-parasitic nematodes across the growing regions. Meloidogyne and Rotylenchulus were found to be the most abundant genera in betel vine crops in all growing regions. Co-inertia analysis between soil properties and nematode abundance indicated that soil chemical characters significantly affect abundances of plant-parasitic nematodes. The type of betel vine crop (sweet and bitter) also has a significant effect on the abundance of plant-parasitic nematodes, with the highest abundance of Meloidogyne reported from the bitter type of betel crop. Spatial distribution depicted a higher abundance of Meloidogyne throughout the North Bengal growing region. Root-knot and reniform nematodes are two important plant-parasitic nematodes of betel vine that might cause economic yield loss to the growers in West Bengal.

Awl nematodes were first described in 1914 from specimens collected at Silver Springs, Florida, and Douglas Lake, Michigan. Species of Dolichodorus are found worldwide, but two species, D. heterocephalus and D. miradvulvus, are the most common in Florida. Usually, awl nematodes are found in moist to wet soil, low areas of fields, and near irrigation ditches and other bodies of fresh water. Because these nematodes prefer moist to wet soils they rarely occur in agricultural fields and are not as well studied as many other plant-parasitic nematodes. This document is EENY-241, one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

The occurrence of soil nematodes from groundnut and chilli crop fields were investigated during the period from November 2013 to February 2014. From the collected soil samples, 13 genera belonging to seven families of three orders under two classes were recorded. Among the observed genera, Meloidogyene, was found to be the predominant on the soil samples of both groundnut and chilli crop fields. Moreover, Meloidogyene, Heterodera and Helicotylenchus were found with prominent values of 138, 92 and 85, respectively and occurred in 16%, 11% and 10% of all soil samples, respectively. Paratrichodorus was found to be the lowest in numbers 27 (3%). The data from recent study indicated that the soil samples of groundnut crop field showed higher incidence of nematodes (57%) than that of chilli crop field (43%).

ABSTRACTCharacteristic of  Nematodes Community at PGS Golf Course Bandar Lampung. Golf course is a unique ecosystem where plant parasitic nematodes inhabit and become  important pest because they reduce the quality of the grass.  The pest problems on golf course can be indicated by its characteristics of nematode community.  Survey on nematodes community at PGS Golf Course Bandar Lampung was conducted from March to December 2004.  The objective was to study the characteristics of nematode community in the part of golf courses hole (green, collar, apron, and fairway).  Soil samples were taken from five holes each of it consists of green, collar, apron, and fairway, respectiveley.  Nematodes extraction was done in Laboratory of Arthropod Pest, Department of Plant Protection University of Lampung.   The result showed that at least 50 nematodes genera of 28 families inhabit PGS. The number of plant parasitic nematode genera was higher than the free-living one.  The characteristic of nematodes community on green and collar was different than on faiway. Nematode abundance and diversity on green and collar were higher than on fairway.  Based on abundance of nematode feeding group, maturity index of free-living nematodes (MI) and that of plant parasitic nematodes (PPI), green and collar part seemed to be more favorable to plant parasitic nematodes than free-living nematodes. The contrary happened for fairway.  Four most dominant genera of plant parasitic nematodes on PGS golf course were Helicotylenchus, Hoplolaimus, Criconemella, and Xiphinema.

Objective: This study in the Senegal River Basin evaluated the effect of three types of compost, made from manure combined with straw, Calotropis procera (Sodom Apple) or Crotalaria juncea (Indian Hemp) , on plant-parasitic as well as free-living nematodes and on the growth of tomato plants. Methodology and results: This study was performed in a greenhouse where a Mongal tomato was grown during 3 months in a soil that had been abandoned due to infestation by nematodes. The treatments were composts of straw, Calotropis procera Crotalaria juncea and control without compost. The soils amended with compost had significantly higher nematode abundances than the unamended. The compost with Crotalaria juncea gave the highest abundance. The soils with compost also had a much lower proportion of plant-parasitic nematodes than the control soil and much higher proportion of bacterivorous nematodes. The height of the plants was positively correlated with the proportion of bacterivorous nematodes and negatively correlated with the proportion of plant-parasitic nematodes. Conclusions and application of the results: The influence on the soil nematode community of compost materials is associated more with their phenol content than the total organic carbon. The Calotropis procera and Crotalaria juncea encourage the growth of the bacterivorous nematode community, which plays an important role in maintaining soil fertility, and the growth of omnivorous and predatory nematodes while limiting the growth of the plant-parasitic nematode community. The results suggested that the compost with Crotalaria juncea seems to be worthwhile pursuing as it maintained the equilibrium between nematode feeding guilds while suppressing plant-parasitic nematodes. Keywords: Compost, Crotalaria, Calotropis, Straw, Nematode, sandy soil.

The purpose of this study was to determine the pH and electrical conductivity in soil of different villages of   barnala district (Punjab,India ) and their harmful effects on human health. Samples of soil were collected from agricultural fields of four different villages of barnala region such as Rure ke kalan, Gunas, Handiaya and cheema from five different layers(0-10 cm; 10-20 cm; 20-30 cm; 30-40 cm and 40-50 cm depth).There are three industrial sites in barnala district and these four villages are located near to these industial sites. In this study, adverse effect of different industries on fields of these four villages were investigated. Handiaya village has high values of pH and electrical conductivity while Gunas and Cheema villages have lowest value of electrical conductivity and pH respectively. when textile effluent reaches the soil or underground water it causes bad effect on human health such as people may suffer from alkalosis which is due to high pH and can lead to arrhythmia which means irregular heartbeat. Alkalosis can induce a coma, it may cause seizures and malfunctioning of kidneys. Due to large value of Electrical conductivity activity of soil micro-organism declines so, the important microbial processes, such as nitrogen cycling, production of nitrous and other N oxide gases, respiration, and decomposition; populations of plant-parasitic nematodes can increase; and increased nitrogen losses.
