Feeding structures and parasitic properties in plant-parasitic nematodes
Plant-parasitic nematodes are one of the most important crop pests in the world. So far, about 4100 species of plant parasites have been identified. They can attack all parts of the plant, such as roots, stems, leaves and seeds. Plant-parasitic nematodes feed on living plant tissues and exhibit a wide variety of interactions with their hosts. In plants, they are generally fed as ectoparasitic, semi-endoparasitic, endoparasitic and mobile ecto-endoparasitic. Ectoparasites never enter the host. Semi-endoparasitic nematodes are fed embedded into the tissue, partly with a part of the body outside. Endoparasitic nematodes completely enter the roots. Immigrant endo-ectoparasite nematodes remain vermiform. The head areas are inserted into cortical cells, where only nutrients are removed. In addition, these feeding types include subgroups. The types of information that feed on plant-parasitic nematodes are important for management strategies. This investigation is started to provide an overview of feeding structures and parasitic properties of plant-parasitic nematodes.
