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.

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.

The life cycles of X. diversicaudatum and X. index were compared under two temperature regimes. For both species under both temperature regimes, peak egg laying occurred during the summer months. Total populations reached their maximum in autumn and their lowest point in spring. Temperature affected the time of onset of egg production in X.

In the plant parasitic nematodes Longidorus leptocephalus (Hooper) and Xiphinema diversicaudatum (Micoletzky) the long spear has two parts, the odontostyle and the odontophore. The odontophore is a modification of the anterior oesophagus and contains three sinuses which lie parallel to and around the food canal.

Microplot studies with Xiphinema diversicaudatum under annual and perennial cropping regimes
Annals of Applied Biology, 1977ABSTRACTAnnual and perennial crops were grown in monoculture over three‐ or four‐year experiments. Strawberry, raspberry and ryegrass maintained high population densities of Xiphinema diversicaudatum. Hop maintained relatively low population densities as did all annual crops tested, including winter wheat, winter beans, spring barley, potatoes, sugar ...

Oviposition in Longidorus elongatus on strawberry crops (Frugaria × ananassa Duchesne) in Scotland began in April, increased rapidly to a peak in May and declined markedly or ceased in July/August; a secondary phase of oviposition terminated by October.
