Stubby root nematode

Paratrichodorus minor

Stubby-root nematodes are very small and can be seen only with the aid of a microscope. They are ectoparasitic nematodes, meaning that they feed on plants while their bodies remain in the soil. They feed primarily on meristem cells of root tips. Stubby-root nematodes are plant-parasitic nematodes in the Triplonchida, an order of nematodes characterized by having a six-layer cuticle (body covering). Stubby-root nematodes are unique among plant-parasitic nematodes because they have an onchiostyle, a curved, solid stylet or spear that is used in feeding (Figure 3). All other plant-parasitic nematodes have straight, hollow stylets.
