      X. americanum is a common species and is found widely in agricultural and forest soils of the United States (1). X. index, which is a vector for Grapevine fanleaf virus, is seen worldwide, commonly associated with grapevine (63). Xiphinema spp. occur in a wide range of soils but mostly prefer loam soils (24). Microbial consortia confer important benefits to animal and plant hosts, and model associations are necessary to examine these types of host/microbe interactions. The accessory nidamental gland (ANG) is a female reproductive organ found among cephalopod mollusks that contains a consortium of bacteria, the exact function of which is unknown. To begin to understand the role of this organ, the.

    As a first step in assessing the importance of plant-parasitic nematodes to California forestry, soil and root samples were taken from 32 kinds of trees in the major forested areas of California. Ninety-seven percent of the samples were from conifers, and 82 percent were from trees important in the lumber industry, mainly ponderosa and Jeffrey pines, coast redwood, Douglas fir, and red fir. THE PATHOLOGICAL EFFECT OF REPRESENTATIVE XIPHINEMA AND LONGIDORUS SPECIES ON SELECTED HOST PLANTS1) BY E. COHN and D. ORION The Volcani Institute of Agricultural Research, Bet Dagan, Israel The effect of representative Longidorus and Xiphinema species on plant growth under controlled conditions, and their histopathology, were investigated. L. africallus, X. .

    To address Objective 1 and assess the effectiveness of cultural management tactics for plant parasitic nematodes based on host tolerance, Fuchs monitored virus inection rates in own-rooted or grafted vines of Vidal in a vineyard naturally infected with Xiphinema americanum and tomato ringspot virus (TRSV) in the Finger Lakes region of New York.

Xiphinema americanum (American dagger nematode) is a species of plant pathogenic is one of many species that belongs to the genus was first described by N. Cobb inwho found it on both sides of the United States on the roots of grass, corn, and citrus trees.

Not only is Xiphinema americanum known to vector plant viruses, but also X. americanum has been Class: Enoplea.

In addition to causing direct damage, certain species of this nematode group are capable of transmitting certain economically important plant viruses such as TRSV, ToRSV, PRMV and by: 2.

Abstract approved The influence of host nutrition on the development of Xiphinema arnericanum Cobb,was investigated by culturing the nematode on alfalfa plants, (Medicago sativa Var. Moapa) in sand containing variations of minerals in Hoaglands ' nutrient solu-tion.

Two Xiphinema americanum-group species from Senegal were successfully cultured on plants in the laboratory and the effects of host plant, temperature and soil moisture were evaluated. Tobacco ringspot virus was transmitted to cucumber seedlings from naturally infected or inoculated Eupatorium capilifolium, Plantago lanceolata, Rumexobtusifolius and Xanthium strumarium plants by hand-picked Xiphinema americanum.

indicates author's summary. J.E.P. The Panel on Plant Health performed a pest categorisation of Xiphinema californicum (Nematoda: Longidoridae) for the EU. The nematode is a well‐defined taxon belonging to a group of morphologically similar species called Xiphinema americanum sensu lato.

The nematode was described from the USA and is present in some North and South American countries. D.J.F. Brown's research works with 2, citations and 3, reads, including: Longidoridae and nepoviruses in Bulgaria and Slovenia. The dagger nematode, Xiphinema americanum, is an efficient vector of TRSV to some host species such as Cucumis sativus.

However, transmission efficiency to soybean is low (McGuire & Douthit, ). Observational reports, based upon rapid downwind directional spread, suggest the potential of efficient natural transmission by arthropod vectors.

Soil samples taken in eastern Kenya contained Xiphinema brevicolle, X. oxycaudatum and X. simile. These species are reported for the first time from Kenya, and X.

oxycaudatum is reported for the first time outside of Nigeria, from where it was originally described and X. simile is reported for the first time outside Europe. The Kenyan specimens have been compared with topotypes (X. brevicolle.

TEMPERATURE Temperature affects nematode activities such as hatching, reproduction, movement, development, and survival and also affects the host plant. Most plant-parasitic nematodes become inactive at a low temperature range of 5 to 15°C, have an optimum range of 15 to 30°C, and become inactive at a high temperature range of 30 to 40°C.

Nematologia Mediterranea, 14, – Google Scholar. (Xiphinema americanum, X. rivesi) Dagger nematode is an economic concern in orchards because it can vector viruses including tomato ringspot virus (TRSV), the cause of apple union necrosis and decline, the Cherry rasp leaf virus (CRLV) which causes flat apple, and Peach rosette mosaic virus (PRMV).

Here we examine an endosymbiont of the dagger nematode, Xiphinema americanum species complex (hereafter, X. americanum), so named for its long protruding spear-like mouthpart, or odontostyle used to penetrate host-plant roots. Xiphinema americanum is a large species-complex comprising about 36 named species forming several major clades.

grams in public health nutrition and are developing accreditation processes for other nutrition degree programs. Just as in research, having the best possible tools is an enormous advantage in teaching and learning. This is the reasoning behind the initiative to launch this series of human nutrition textbooks designed for use worldwide.

Nematodes parasitizing bamboo are Pratylenchus, Xiphinema, Meloidogyne, Longidorus, Paralongidorus, Trichodorus and Criconemoides. Among all nematodes, Pratylenchus brachyurus and Xiphinema americanum are the most common and damaging ones. Nematode attack facilitates the invasion by soil borne fungi and bacteria resulting in severe damage to.
