Feeding types of plant-parasitic nematodes. This article is an attempt to list all agricultural pest nematodes. Species are sorted in alphabetical order of Latin name. A
Rhabditida is an order of free-living, parasitic and microbivorous nematodes living in soil. The Cephalobidae , Panagrolaimidae , Steinernematidae , and Strongyloididae seem to be closer to the Tylenchia , regardless of whether these are merged with the Rhabditia or not.
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.
In order to avoid competition, some species of infective juveniles are able to judge the quality of a host before penetration. The infective juveniles of S. carpocapsae are repelled by 24-hour-old infections, likely by the smell of their own species' mutualistic bacteria (Grewal et al. 1997).
Root-knot nematodes are plant-parasitic nematodes from the genus Meloidogyne. They exist in soil in areas with hot climates or short winters. About 2000 species of plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss . [ 1 ]
Nematodes (Nematoda or roundworms) are a phylum of animals. The phylum is subdivided in 3 classes : Chromadorea, Enoplea and Secernentea. Subcategories.
These can be categorized into three groups; cestodes, nematodes and trematodes. Examples include: Acanthocephala; Ascariasis (roundworms) Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
