A Redescription of Xiphinema Italiae Meyl, 1953 and Its Relationship To Xiphinema Arenarium Luc Et Dalmasso, 1963 and Xiphinema Conurum Siddiqi, 1964

Nematologica, 1966
A redescription of the female of Xiphinema italiae based on specimens collected in the type locality is given. Males and larval stages of this species are described and figured. Xiphinema drenarium was found to be of identical taxonomic status, and is therefore synonymized with X. italiae. The morphological similarities between X. italiae and Xiphinema

The Genus Xiphinema (Dorylaimida) in Surinam

Nematologica, 1972
Investigation of the Xiphinema material collected in Surinam by den Ouden in 1964 and by Maas in 1965-1970 showed six species to occur, four of which are new. X. filicaudatum n. sp. is characterized by a spear length of 300 μ or more and by its very long filiform tail. X. surinamense n.

Observations On Spear-Formation in Xiphinema

Nematologica, 1963
The process of spear-formation in Xiphinema could be traced by studying larvae of different stages fixed while moulting. It was found that growth of the new odontostyl started during the early stages of moulting and ended before the old cuticle was entirely shed.

Ecology of Xiphinema and Longidorus

1975
In nematological literature there are few publications devoted entirely to ecology but on the other hand there are equally few which do not contain some information of an ecological nature. The majority of available information on the ecology of the approximately 70 Xiphinema and 40 Longidorus species is represented by short remarks connected with ...

Feeding of Trichodorus, Longidorus and Xiphinema

1975
The discovery of plant root ectoparasitism by nematodes is as recent as 1951 when Christie and Perry (2) experimentally proved that a Trichodorus sp. (later named T. christiei) produces stubbyroot symptoms on the roots of beet and sweet corn. Ten years later, the genus Trichodorus again attracted much attention when, in the same year, three species (26)

Observations On the Feeding of Xiphinema Diversicaudatum

Nematologica, 1976
During a study of Xiphinema diversicaudatum feeding on Petunia hybrida growing in agar the two main types of feeding activity, apart from penetration and retraction, were periods of oesophageal bulb pulsation and long periods of quiescence. During oesophageal bulb pulsation the nematodes were ingesting plant cell constituents.

Ultrastructure of sperm cells in the female gonoduct of Xiphinema

Tissue and Cell, 1991
The ultrastructure of the sperm cells in the female gonoduct of the nematodes Xiphinema theresiae and X. pinoides is described. The nucleus of the sperm cells is composed of several electron-dense clumps of chromatin that is not surrounded by a nuclear envelope.

Taxonomy of Xiphinema Cobb, 1913

1975
The first species of Xiphinema described as such was X. americanum, the type species, by Cobb in 1913 (2). But twenty years before (1), Cobb himself had described a nematode from the Fiji Islands under the name of Tylencholaimus ensiculiferus, which was attributed later to Xiphinema by Thorne (13) and of which the accurate redescription, on topotypes ...

Acquisition and transmission of Grapevine fanleaf virus (GFLV) by Xiphinema index and Xiphinema italiae (Longidoridae)

Journal of Helminthology
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.
