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.
Nematodes emerging from a wax moth larva cadaver. Entomopathogenic nematodes (EPN) are a group of nematodes (thread worms), that cause death to insects. The term entomopathogenic has a Greek origin, with entomon, meaning insect, and pathogenic, which means causing disease.

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.
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 ]
The abomasal nematode O. ostertagi is a clade V nematode of the order Strongylida, the family Trichostrongylidae and genus Ostertagia. [1] Ransom first described the genus Ostertagia in 1907, which currently contains approximately 15 species. All species of the genus Ostertagia infect domestic or wild ruminants.
Tylenchidae is a family of nematodes. They are an important group of soil dwelling species that frequently contributes as much as 30% to the nematode species richness of soil samples. [2] They diverged relatively early on and many species pose little risk to economically important plant species. [2]
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.
