Dolichodoridae

They infect a wide variety of crops, including cereals, vegetables, forage grasses, and ornamental turf. By extracting nutrients from the roots, these nematodes significantly stress the plant, making it more susceptible to environmental factors and secondary infections from bacteria or fungi.

The biology of Dolichodoridae revolves around their specialized feeding apparatus, known as a stylet. They move through soil pores to locate suitable roots, where they puncture cells to ingest cytoplasmic contents. Their development is influenced by soil temperature, moisture levels, and the availability of host root tissues, which facilitate rapid reproduction cycles.

The damage caused by these nematodes is primarily observed in the root system, which shows reduced development, stunted growth, and necrosis of the root tips. Above-ground symptoms include wilting, chlorosis, and patchy growth patterns across the field, as the plant's ability to uptake water and nutrients is severely compromised.

Management strategies focus on minimizing population density and preventing spread. Key practices include:

• Crop rotation with non-host plant species.
• Utilizing soil solarization or bio-fumigation techniques.
• Ensuring proper irrigation and fertilization to encourage vigorous root growth.
• Applying nematicides when threshold levels of infestation are exceeded in sensitive commercial crops.
