Morphology and Anatomy:

Nematode is 4.0-5.5mm long.
Back to Top

Distribution:

Permanent pasture and woodland sites in Europe and parts of the U.S.; also found in Australia.

 

Back to Top

Economic Importance:

 A-rated pests in California.

 

Back to Top

Feeding:

Nematode feeds at root tips; stylet reaches vascular tissue and causes local necrosis and hypertrophy.

 

Back to Top

Hosts:

 Pasture, weeds, trees, roses, and hops. 

For an extensive list of host plant species and their susceptibility, copy the name

Life Cycle:

Can be as long as 3 years; female may live up to 5 years; reported to survive 3 years in the absence of plants.

Damage:

Nematode causes direct damage and can transmit viruses.  

Transmits arabis mosaic virus in Europe to a range of crops, including hop, cherry, etc.

Virus particles attach to cuticular lining of esophagus, especially in the anterior region of odontophore.  During molt, esophageal lining passes through the intestine, and juveniles lose infectivity.  Virus can be retained in adults for up to 8 months.

Management:

Preplant soil fumigation with 1,3-Dichloropropene (Telone) at 40 gpa.; methyl bromide at 1000lb/ac to control to 28 in. 

Nematode is tolerant of starvation, thus making fallow ineffective. 

Control of nematode is desirable to reduce virus infection of plants.

Resistance

For a list of plant species or cultivars (if any) reported to be immune or to have some level of resistance to this nematode species, copy the name

Xiphinema diversicaudatum
