Stubby root nematodes

[R]Description
Small-sized (1 mm long) and bisexual (sex ratio= 50) nematodes provided with a mouth spear (*) .

[R]Biology
- These nematodes are ectophytes living in the rhizosphere of numerous trees, shrubs and market-garden crops.
- They feed by inserting their mouth spear into the radicles whose contents they pump out, their body remaining in the soil. They multiply very quickly in hot and humid soils and populations of thousands of individuals may be found attacking a radicle.

[R]Damage
- Their presence may lead to a widespread and severe weakening of crops which decline and stop growing.
- The numerous penetrations lead to the formation of blisters which distort tissues, hence the name 'stubby root nematode'.
