Microscopic, unsegmented worms known to feed on African Violets. See Leaf Nematodes and Root Nematodes.
Extremely diverse aquatic macroinvertebrates; roundworms; long, thin aquatic worms that writhe like snakes.
A large, widespread, and diverse group of free-living and parasitic unsegmented worms. They are particularly important in the soil and can be important pests of plants and parasites of humans and domestic animals.
pests, small and worm-like, that feed on roots.
A class of slender, unsegmented worms, often parasitic. a.k.a. eelworms, especially when phytoparasitic.
Round-worms of various sizes, frequently parasitic, infesting plants and animals. Usually passes part of its life cycle in the soil.
tiny worms; some are eaten by fungi
Non-segmented, microscopic worm like organisms that feed on plants, animals and even humans
Roundworms. Nematoda is the most common phyla of animals. Over 20,000 species have been described.
organisms in the soil or introduced in a soilless medium by water or other contamination and cause swelling of plant roots which in turn restricts water uptake leading to wilting of the plant
small, unsegmented worms common in soils and sediments.
Roundworms, any of which are pathogenic for plants and sometimes animals.
Invertebrates with a cylindrical body, a conspicuous body cavity, and a complete digestive tract.
A group of worms, some of which may cause intestinal and other diseases.
Generally microscopic tubular worms, usually living free in moist soil, water, and decaying matter, or as parasites of plants and animals. Obligate - Necessary; obliged. An obligate parasite is an organism that can live only on living tissue.
Microscopic, elongated worms that live on other organisms in the soil.
There are at least 12,000 named species of the small unsegmented worms called nematodes. Shovel some healthy soil. Within that shovelful there may be a million nematodes. Some species parasitize humans, others animals, some parasitize other nematodes, and still others feed on plant roots. Plants attacked by nematodes suffer stunted growth and sometimes yellowing. Control pest nematodes by improving soil: humus rich soil supports beneficial nematodes and other soil bacteria. Certain species of nematodes can be purchased as beneficials and will help control insect populations by feeding on insect larvae.
Parasitic worms of the class Nematoda, which includes the intestinal roundworms, filarial worms, lungworms, kidney worms, heartworms, etc.
Microscopic worms that live in the soil and feed on vine roots. Nematodes can stunt the growth of vines, and transmit viral diseases.
are microscopic worms with pearly egg masses. They stimulate injured plant tissue to form galls, which block the flow of water and nutrients to the plant. This leads to stunting, wilting, and yellowing. Roots appear scabby.
A type of helminth characterized by long, cylindrical bodies; commonly known as roundworms.
Unsegmented roundworms, abundant in many soils, which may infect and damage the roots of plants.
These are a large group of thread-like creatures which are principally parasitic and can be quite devastating to their host, although within the confines of a garden pond they are rarely a serious problem owing to their complex life cycle.
Tiny, usually microscopic, unsegmented worms. Some are parasites of animals or plants. Most live free in the soil.
microscopic, elongated, cylindrical, parasitic worms that live in water and soil.
A common name for any roundworm of the phylum Nematoda.
