Abstract Grapevine fanleaf virus (GFLV) is one of the most severe virus diseases of grapevines, causing fanleaf degeneration that is transmitted by Xiphinema index. This paper aims to isolate Xiphinema species from Tunisian vineyard soil samples and assess their ability to acquire and transmit GFLV under natural and controlled conditions.

Abstract A short insert genomic library for Xiphinema index, the natural vector of Grapevine Fanleaf Virus, was constructed from degenerate oligonucleotide primed PCR (DOP-PCR) products. The genomic library was screened for (CA)n microsatellites.

Abstract A method for the orientation of nematodes for cryoultramicrotomy is described. Comparison of cryosections with sections prepared by conventional electron microscopic procedures showed satisfactory resolution of structural details in frozen sections. Labeling of frozen sections en face was achieved by cationized ferritin and colloidal iron.

Analysis of expressed sequence tags from the ectoparasitic nematode Xiphinema index
Nematology, 2005AbstractWe report the results of a small-scale expressed sequence tag project performed on the ectoparasitic nematode Xiphinema index. Approximately 1400 genes were sequenced, 70% from a cDNA library generated from dissected basal bulbs (containing the pharyngeal gland cells) and 30% from cDNA libraries generated from whole mixed stage nematodes.

Feeding Phases of Xiphinema Index and Associated Processes in the Feeding Apparatus
Nematologica, 1977Feeding mechanisms in Xiphinema index were observed, filmed and later analysed with the aid of cine film evaluation facilities. All the studies were made with X. index feeding on root tips of Ficus carica seedlings on agar culture in special observation chambers.

Vector-Efficiency of Xiphinema Index in the Transmission of Grapevine Fanleaf Virus 1)
Nematologica, 1968Xiphinema index Thorne & Allen acquired and transmitted grapevine fanleaf virus (GFV) within access times of 15 minutes. The virus was retained for at least 12 weeks when the nematodes were maintained on fig but not in fallow soil. Effects of soil temperature and axenization of nematodes on the transmission of GFV also have been demonstrated.

On the occurence of Xiphinema index Thorne et Allen in Chile.
2004A nematode survey was carried out during the years 1998-2004 in Chile to assess the occurrence of the dagger nematode, Xiphinema index, in vineyards and on fig trees grown in backyards around dwelling. Approximately 45% of samples were positive for the nematode.

Stereological analysis of 10 oesophageal bulbs of Xiphinema index revealed the component parts and their fractional volumes to be dorsal gland cell (34 % ), subventral gland cells (25 % ), radial muscle (30 % ), peripheral muscle (3.9%), nerve (3.4%), basement membrane (3.2%) and pump wall (0.99%).

Feeding Behaviour and Reproduction of Xiphinema Index On Some Herbaceous Test Plants
Nematologica, 1973In pot tests, Xiphinema index reproduced on Vitis vinifera, Solanum tuberosum, S. nigrum, S. dulcamara and Lycopersicon esculentum but not on Lolium perenne and Brassica oleracea. Feeding behaviour of X. index was studied on L. perenne, B. oleracea, S. dulcamara and L. esculentum.
