SUMMARYSections through the odontophore of Xiphinema diversicaudatum showed two types of staining for carbohydrates using the periodic acid ‐ thiosemicarbazide ‐silver proteinate (PA‐TSC‐SP) reaction. The first consisted of thin, localised, intensely‐stained patches on the lining of the food canal of all the specimens examined.

The Reproductive Potential of Xiphinema Diversicaudatum On Strawberry
Nematologica, 1970The reproductive potential of Xiphinema diversicaudatum was apparently little affected by population density, even when this considerably exceeded that normally found in the field or when it was as low as one female and one male inoculated separately in 125 ml soil. The mean reproductive rate was 7.3 (S.D. 2.0).

Ultrastructural studies on the nematode Xiphinema diversicaudatum: Oogenesis and fertilization
Tissue and Cell, 1993Oogenesis and fertilization in longidorid nematodes has been examined for the first time at electron microscope level in Xiphinema diversicaudatum. Oogonia in the germinative zone of the ovary are irregularly shaped and lie adjacent to each other or separated by processes of the epithelial cells of the ovary.

Ultrastructural studies on the nematode Xiphinema diversicaudatum: Egg shell formation
Tissue and Cell, 1993The ultrastructure of the formation of the egg shell in the longidorid nematode Xiphinema diversicaudatum is described. Upon fertilization a vitelline membrane, which constitutes the vitelline layer of the egg shell, is formed. The chitinous layer is secreted in the perivitelline space, between the vitelline layer and the egg cell membrane.

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 ...
