Longidoridae
Longidoridae is a family of obligate plant-parasitic nematodes. These nematodes are commonly known as dagger nematodes due to their prominent, hollow, spear-like stylet, which they use to feed on plant cells. They are characterized by their large size, often exceeding 2 mm in length, making them among the largest known soil nematodes. The stylet is a crucial diagnostic feature within the family.
These nematodes inhabit a wide range of soil environments globally, particularly in temperate and subtropical regions.
A significant aspect of Longidoridae is their ability to transmit plant viruses. Many species act as vectors
