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.

Economic Importance:

 A-rated pests in California.

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.

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.
