Are there Variants to Mesocriconema
xenoplax in California?
Ring nematode causes substantial damage
to woody perennial crops in California. There is a critical
need to develop nonchemical methods of control for this nematode.
Development of resistant rootstocks, for example, is hindered
because there appear to be population variants which have not
been distinguishable by traditional microscopic analysis. A
multi-disciplinary approach to studying this problem that involves
host-range testing, sophisticated video morphology screening,
database analysis, and development of molecular identification
techniques is proposed.

The grapevine in
the foreground has susceptible rootstock and a generally aggressively
reproducing ring nematode population; the plant in the background
has more resistant rootstock as well as a usually more slowly
reproducing nematode strain
