Thân thiện

A gardener examines a plant leaf for signs of eelworm damage.

Definition

Noun: 1. A small, slender, free-living or plant-parasitic roundworm: An eelworm is any of various tiny, unsegmented worms, typically microscopic, that belong to the class Nematoda. They are characterized by their long, cylindrical, and often thread-like bodies. Many species live freely in soil and water, while others are significant parasites of plants, causing damage to roots, stems, and leaves.

Usage Examples

• Noun:
  • The gardener identified eelworms as the cause of the stunted root growth.
  • A soil sample revealed a high population of free-living eelworms.
  • This particular eelworm species is a major pest for potato crops.

Advanced Usage

• The term "eelworm" is often used interchangeably with "nematode" in an agricultural or gardening context, particularly when referring to plant-parasitic species. In strict scientific classification, "nematode" is the broader term for the entire phylum, while "eelworm" is a common name for certain small, often parasitic nematodes.

Variants and Related Words

• Nematode (n): The scientific term for the phylum of roundworms to which eelworms belong. It is a more general and technically precise term.
  • Plant-parasitic nematodes, such as root-knot nematodes, are sometimes called eelworms.
• Roundworm (n): A common name for nematodes, describing their typical body shape.

Synonyms

• Nematode
• Roundworm (in a general sense)
• Plant parasite (for the parasitic species)

Notes on Meaning

• The primary meaning of eelworm centers on its identity as a type of nematode. Its key distinguishing features are its small size and its ecological role, which can be either free-living in soil/water or parasitic on plants. It is not typically used to describe parasitic roundworms that infect animals or humans.
