Scutellonema brachyurum (British spiral nematode, Carolina spiral nematode) is a plant pathogenic nematode Infecting African violets.
Enoplea (enopleans) is a class, which with the classes Secernentea and Chromadorea make up the phylum Nematoda in current taxonomy. The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea.
The Chromadorea are a class of the roundworm phylum, Nematoda. They contain a single subclass (Chromadoria) and several orders. With such a redundant arrangement, the Chromadoria are liable to be divided if the orders are found to form several clades, or abandoned if they are found to constitute a single radiation.
Rotylenchulus reniformis, the reniform nematode, is a species of parasitic nematode of plants with a worldwide distribution in the tropical and subtropical regions.
Pratylenchus vulnus is a species of plant pathogenic nematode best known for infecting Persian walnut. It is also known to infest potatoes, apricots, peaches and nectarines, holiday cacti, grape and citruses.
Helicotylenchus dihystera is a plant pathogenic nematode. It is known to inhabit sugarcane, rice, potatoes, corn, peanut, millet, sorghum, banana and forest trees.
Helicotylenchus multicinctus is a plant pathogenic nematode that affects primarily bananas and plantains. Nematodes of the genus Helicotylenchus are spiral nematodes and feed on a large variety of plant species.
Scutellonema cavenessi is a plant pathogenic nematode. This parasite destroys peanuts and soybeans.
Diplogasterida was an order of nematodes. It was sometimes placed in a monotypic subclass Diplogasteria, but molecular phylogenetic evidence has shown it to be embedded in the family Rhabditidae. The confusion of having a hierarchical nesting of groups that were formerly mutually exclusive has led to a profusion of names. Although completely revised taxonomy of nematodes that builds on recent classification systems as well as recent phylogenetic evidence is still necessary, most contemporary taxonomic studies now treat all groups listed under "Diplogasterina" below as a single family, Diplogastridae.
Protostomia is the clade of animals once thought to be characterized by the formation of the organism's mouth before its anus during embryonic development. This nature has since been discovered to be extremely variable among Protostomia's members, although the reverse is typically true of its sister clade, Deuterostomia. Well known examples of protostomes are arthropods, molluscs, annelids, flatworms and nematodes. They are also called schizocoelomates since schizocoely typically occurs in them.
The nematodes, roundworms or eelworms constitute the phylum Nematoda. They are a diverse animal phylum inhabiting a broad range of environments. Most species are free-living, feeding on microorganisms, but there are many that are parasitic. The parasitic worms (helminths) are the cause of soil-transmitted helminthiases.
Mermithidae is a family of nematode worms that are endoparasites in arthropods. As early as 1877, Mermithidae was listed as one of nine subdivisions of the Nematoidea. Mermithidae are confused with the horsehair worms of the phylum Nematomorpha that have a similar life history and appearance.
A nematode infection is a type of helminthiasis caused by organisms in the nematode phylum.
Spiruroidea is a superfamily of Spirurida.
Hoplolaimidae is a family of plant pathogenic nematodes. It has two subfamilies, Hoplolaiminae and Rotylenchulinae. Typically hoplolaimids are ecto- or semi endoparasites of higher plants.
Helicotylenchus is a genus of nematodes in the family Hoplolaimidae. They are known generally as spiral nematodes. They are found worldwide because they can live and survive in a wide range of habitats. They are among the most common parasitic nematodes of plants; found in corn, bananas, grass, soybeans.
Anthidium utahense is a species of bee in the family Megachilidae, the leaf-cutter, carder, or mason bees.
Legerella is a genus of parasitic alveolates of the phylum Apicomplexa. Species in this genus that usually infect the malpighian tubules of invertebrates.
Enoplida is an order of nematodes. It is one of two orders in Enoplia, which is one of two subclasses in Class Enoplea.
Didelta spinosa (L.f.) Aiton, belonging to the family of Asteraceae, is a Southern African woody shrub or small tree endemic to the West Coast and found from Saldanha Bay in the south across the Gariep into the south-west corner of Namibia. Growing 2–3 m tall and drought-resistant, its preferred habitat is on dry, rocky slopes. This species was introduced to Europe by Thunberg and Masson.
Caenorhabditis angaria is a small nematode, in the same genus as the model organism Caenorhabditis elegans. The name is from the Latin after the tendency to ride weevils. Prior to 2011, the species was referred to as C. sp. 2, C. sp. 3, and C. sp. PS1010. Its genome was sequenced at the California Institute of Technology in 2010. This species is gonochoristic. It has distinct morphology and behavior compared to C. elegans; notably, C. angaria males exhibit a spiral mating behavior. Its divergence from C. elegans is similar to the distance between humans and fish. C. castelli is its closest relative, and the two species can produce F1 hybrids.
