Reported only from South Africa and USA. In USA it is reported from Texas, New Mexico, Arizona, Oklahoma and Florida, primarily on roots of pecan trees.
Pecan tree seedlings are stressed and grow poorly. Seedlings have dead shoots in canopy. Yield decline reported for mature trees in New Mexico.
Feeding site establishment and development typical of genus.
Known hosts are pecan, Carya illinoensis, hickory and walnut trees (Starr et al., 2006)..
Reported non-hosts include beans, peas, cowpea, tomato, peach and weeping lovegrass (Marais and Heyns, 1990).
Female body ruptures root cortex and may protrude with the egg mass on the root surface.
Both major roots and young roots have prominent galling. Seedlings stressed with dead shoots (Brito et al., 2006)..
A two-year host free rotation is suggested for tree nurseries (Brito et al. 2006)..
