microbiology Nematodes

  • Predarious

    ones feed on other nematodes, bacteria and fungi and other minute animals

  • Plant parasitic

    ones feed on plants and algae

  • Saphrophytes

    s feed on dead or decaying organic matter

  • Nematodes

    Thread-like unsegmented worms which are elongated and cylindrical in shape.

  • Stylet

    which is a hollow needle-like spear used for obtaining nutrients from the host

  • Ectoparasites

    feed from the outside and only the stylet enters the plant cells. They do not enter the roots.

  • Semi-endoparasites

    feed by burying the front partof the body while the posterior portion is outside the host.

  • Rotylenchulus, Helicotylenchus

    semi-endoparasites examples

  • Endoparasites

    the entire nematode body enters the plant cells while it feeds.

  • Meloidogyne, Heterodera

    endoparasites examples

  • Migratory

    move from one part of the plant to the another portion of the host, or move from the plant to the soil and back and forth.

  • Radopholus similis, Ditylenchus dipsaci

    migratory example

  • Sedentary

    attached themselves to the roots or burrow into the root.

  • Meloidogyne, Rotylenchulus

    sedentary example

  • Radopholus similis

    Toppling disease of banana

  • Rotylenchulus reniformis

    attacks cotton, cowpea, etc

  • Meloidogyne incognita

    - root galls of tomato, okra rice, etc.

  • Heterodera schachtii

    brassica vegetables, sugar beet

  • Ditylenchus dipsaci

    (onion, garlic, carrots, peas, •potatoes, etc.

  • Tylenchulus semi-penetrans

    - citrus root nematod

  • Helicotylenchus spp.

    wide host range, including fruit crops, vegetables, agronomic crops, ornamental plants etc
