Nematodes are microscopic animals, are fourth in the animal kingdom so it refers to the number of species largest edge. They are commonly known as roundworms because of the shape of your body in a cross section.
The number of species that parasitize man directly and parasitic plants (plant parasitic nematodes) are a very small number compared to the number of species of the phylum Nematoda.
Plant parasitic nematodes can attack roots, stalks, stems, buds, leaves, flowers and seeds; however, the infected tissue varies with species and host fitonematodo. In the case of plant parasitic nematodes, diseases are categorized according to the parasitic habitat and symptoms in the root system and aerial tissue.
Plant parasitic nematodes root system are:
- Ectoparasites: nematodes that feed without penetrating to the roots. In general, ectoparasites are larger and longer stilettos endoparasites with the aim to penetrate the root tissue. This group includes the genera: Helicotylenchus, Paratylenchus, Trichodorus Hemicriconemoides, Longidorus, Paratrichodorus, among others.
- Endoparasites: nematodes are fully penetrate into the roots; therefore they feed, grow and lay eggs within or adhered thereto. These nematodes are divided into sedentary endoparasites such as the genera: Meloidogyne, Globodera, Heterodera; and migratory endoparasites Radopholus and Pratylenchus.
