Mermis nigrescens. Order Enoplida. Suborder Alaimina Superfamily Alaimoidea Micoletzky, 1922. Alaimidae Micoletzky, 1922; Suborder Campydorina Superfamily Campydoroidea Jairajpuri, 1976
About 90% of nematodes reside in the top 15 cm (6") of soil. Nematodes do not decompose organic matter, but, instead, are parasitic and free-living organisms that feed on living material. Nematodes can effectively regulate bacterial population and community composition—they may eat up to 5,000 bacteria per minute.
Nematode becomes a concern to farmers when the number feeding on the roots exceeds a certain threshold, above which the plant is unable to grow normally. This threshold varies according to the species of nematode. For Pratylenchus zeae, because the level exceeds in many fields in Australia so that P. zeae is
Enoplea (enopleans) is a class, which with the classes Secernentea [1] and Chromadorea make up the phylum Nematoda in current taxonomy. [2] [3] [4] The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea.
Belonolaimus longicaudatus (Sting nematode) is a common parasite of grasses and other plant crops and products. It is the most destructive nematode pest of turf grass, and it also attacks a wide range of fruit, vegetable, and fiber crops such as citrus, cotton, ornamentals, and forage. The sting nematode is a migratory ectoparasite of roots.
Heterodera schachtii, [2] [3] the beet cyst eelworm or sugarbeet nematode, is a plant pathogenic nematode. It infects more than 200 different plants including economically important crops such as sugar beets, cabbage, broccoli, and radish. H. schachtii is found worldwide. Affected plants are marked by stunted growth, wilting, yellowing ...
Trichodoridae (stubby-root nematodes, trichodorids) is a family of terrestrial root feeding nematodes, being one of two that constitute suborder Triplonchida. [ 3 ] [ 4 ] They are economically important plant parasites and virus vectors.
