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.
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.
When sugar beets are grown on a virgin field and a given amount of H. schachtii is introduced, beets are most vulnerable during the first several seasons. With the continued presence of the nematode in a field, infectious fungi levels rise, nematode concentrations decrease, and crop production increases. [10]
Kuhn [18] (1874) is thought to be the first to use soil fumigation to control nematodes, applying carbon disulfide treatments in sugar beet fields in Germany. In Europe from 1870 to 1910, nematological research focused heavily on controlling the sugar beet nematode as sugar beet production became an important economy during this time in the Old World.
Comparing the life histories of nematodes and target pests can often explain such failures (Gaugler et al. 1997). Each nematode species has a unique array of characteristics, including different environmental tolerances, dispersal tendencies, and foraging behaviors (Lewis et al. 1998). Increased knowledge about the factors that influence EPN ...
Nematodes (Nematoda or roundworms) are a phylum of animals. The phylum is subdivided in 3 classes : Chromadorea, Enoplea and Secernentea. Subcategories.
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]
