Nematode
The nematodes ( or ; ; ), roundworms or eelworms constitute the phylum Nematoda. Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic. Parasitic worms (helminths) are the cause of soil-transmitted helminthiases. They are classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa. Unlike the flatworms, nematodes have a tubular digestive system, with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species are uncertain. A 2013 survey of animal biodiversity suggested there are over 25,000. Estimates of the total number of extant species are su ...

Aphelenchoides
''Aphelenchoides'' is a genus of mycetophagous nematodes. Some species are plant pathogenic foliar nematodes. Taxonomy In 1961 Sanwal listed 33 species and provided a key. The most important species of these are '' Aphelenchoides ritzemabosi'', the chrysanthemum foliar nematode; ''Aphelenchoides fragariae ''Aphelenchoides'' is a genus of mycetophagous nematodes. Some species are plant pathogenic foliar nematodes. Taxonomy In 1961 Sanwal listed 33 species and provided a key. The most important species of these are '' Aphelenchoides ritzemabosi ...'', the spring crimp or spring dwarf nematode of strawberry, which also attacks many ornamentals; and '' Aphelenchoides besseyi'', causing summer crimp or dwarf of strawberry and white tip of rice. Several species of this genus feed ectoparasitically and endoparasitically on aboveground plant parts. References Bibliography * George Agrios (2005): ''Plant Pathology, Fifth Edition''.
