On the structure of the Z pseudo-organ in Xiphinema diversicaudatum
International Journal for Parasitology, 1984Abstract The structure of the Z pseudo-organ in Xiphinema diversicaudatum consists of a muscular mass of about 80 cells arranged in rings of four cells each. These cells have peripheral nuclei and are connected with a glandular monolayered epithelium, which lines the lumen of the Z pseudo-organ.

Transmission of arabis mosaic virus by the nematode Xiphinema diversicaudatum (Micol.)
Virology, 1961Abstract After dagger nematodes Xiphinema diversicaudatum (Micol.), were shown to transmit arabis mosaic virus to strawberry plants, the mode of transmission was studied using Petunia hybrida Vilm. seedlings as test plants. Approximately 30% of the nematodes reared on roots of infected strawberry plants transmitted the virus, and batches of ten ...

Observations On the Feeding of Xiphinema Diversicaudatum
Nematologica, 1976During 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.

Labelling of Longidorus Elongat Us and Xiphinema Diversicaudatum With Glucose [14C]
Nematologica, 1971Longidorus elongatus and Xiphinema diversicaudatum were labelled by incubation in a dilute aqueous solution of glucose {14C}, both species becoming much more radioactive than Ditylenchus dipsaci. Labelling of microbiological contaminants on the nematode cuticle was minimised by using antibiotics, which did not seem to affect nematode viability.

Fine Structure of Sense Organs in the Mid-Region of Xiphinema Diversicaudatum Females
Nematologica, 1993The fine structure of the numerous pores in the median body region of Xiphinema diversicaudatum females was observed by transmission electron microscopy. Each receptor has a characteristic number and arrangement of neurons. Two dendrites with the typical microtubule pattern 9×2, embedded within electron dense material, and representing the sensory ...

The Survival of Xiphinema Diversicaudatum in Plant-Free Soil
Nematologica, 1980Experiments to study the survival of Xiphinema diversicaudatum in field soil in the absence of vascular plants demonstrated the presence of a 'survival factor' which was destroyed by heating to above 60° and by fumigation with the nematicide DD, survived drying and extensive soil washing, fractionation and reconstitution, was absent from soil leachings

Parasitism and Pathogenicity of Xiphinema Diversicaudatum, an Ectoparasitic Nematode
Nematologica, 1957Xiphinema diversicaudatum, ein verdachtiger pflanzenparasitischer Nematode, trat in Gewachshausern in Verbindung mit kummernden Rosen auf. Um nachzuweisen, ob dieser Nematode parasitisch lebt und pathogen ist, wurden Kulturen angesetzt und mit diesen Manetti Rose, Rosa sp.

Transmission of the hop strain of arabis mosaic virus by Xiphinema diversicaudatum*
Annals of Applied Biology, 1974SUMMARYHop plants became infected with the hop strain of arabis mosaic virus (AMV(H)) when grown in hopfield and woodland soil in which infected plants had been growing. Infection occurred in soil infested with the dagger nematode Xiphinema diversicaudatum, but neither in uninfested soil nor in soil previously heated to kill nematodes.

Nuclear changes induced by the nematodeXiphinema diversicaudatum in root-tips of strawberry
The Histochemical Journal, 1984Feeding by the nematode X. diversicaudatum caused a progressive increase in the DNA content and size of strawberry nuclei. After four days feeding, nuclei had DNA values intermediate between 8C and 16C and had increased in size from a mean of 17 micron2 for control root tips to 49 micron2.

The influence of some environmental factors on the distribution of Xiphinema diversicaudatum and X. pachtaicurn in Continental Spain has been studied taking into account the allopatric distribution of both species in Europe. The relationships that X. diversicaudaturn and X.
