Trombidiformes
The Trombidiformes are a large, diverse order of mites. Taxonomy In 1998, Trombidiformes was divided into the Sphaerolichida and the Prostigmata. The group has few synapomorphies by which it can be defined, unlike the other major group of acariform mites, Sarcoptiformes. Its members include medically important mites (such as ''Demodex'', the chiggers, and scrub-itch mites) and many agriculturally important species, including the spider mites (Tetranychidae). The superfamily Eriophyoidea, traditionally considered members of the Trombidiformes, have been found to be basal mites in genomic analyses, sister to the clade containing Sarcoptiformes and Trombidiformes. The 2004 classification retained the two suborders, comprising around 125 families and more than 22,000 described species. In the 2011 revised classification, the order now contains 151 families, 2235 genera and 25,821 species, and there were another 10 species with 24 species that present only as fossils. These 151 ...

Acariformes
The Acariformes, also known as the Actinotrichida, are the most diverse of the two superorders of mites. Over 32,000 described species are found in 351 families, with an estimated total of 440,000 to 929,000 species, including undescribed species. Systematics and taxonomy The Acariformes can be divided into two main clades – Sarcoptiformes and Trombidiformes. In addition, a paraphyletic group containing primitive forms, the Endeostigmata, was formerly also considered distinct. The latter is composed of only 10 families of little-studied, minute, soft-bodied mites that ingest solid food, such as fungi, algae, and soft-bodied invertebrates such as nematodes, rotifers, and tardigrades. These clades were formerly considered suborders, but this does not allow for a sufficiently precise classification of the mites and is abolished in more modern treatments; the Endeostigmata are variously considered to form a suborder on their own (the old view) or are included mainly in the Sarcopt ...

Prostigmata
The Prostigmata is a suborder of mites belonging to the order Trombidiformes, which contains the "sucking" members of the "true mites" (Acariformes). Many species are notorious pests on plants. Well-known examples of prostigmatan plant parasites are species of the gall mites (Eriophyidae, e.g. the redberry mite '' Acalitus essigi''), Tarsonemidae (e.g. the cyclamen mite, '' Steneotarsonemus pallidus''), and the spider mites of the Tetranychidae (e.g. the two-spotted spider mite, ''Tetranychus urticae''). Other Prostigmata live as parasites on vertebrates (e.g. ''Demodex'' mites of the Demodecidae) or invertebrates (e.g. ''Polydiscia deuterosminthurus'' of the Tanaupodidae or the honeybee tracheal mite, ''Acarapis woodi'', of the Tarsonemidae). There are also some forms (e.g. Smarididae) that are predators of small invertebrates – including smaller Prostigmata – yet others have a more varied lifestyle (e.g. Tydeidae) or switch their food sources as they mature (e.g. Erythrae ...

Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eriophyoidea
Eriophyoidea are a superfamily of herbivorous mites. All post-embryonic instars lack the third and fourth pairs of legs. The respiratory system is also absent. The taxonomy of this group has always been confused. There were families created for few or even one species, i.e. Ashieldophyidae Mohanasundaram, 1984 and Pentasetacidae Shevchenko, 1991 but these families were placed by J. W. Amrine and T. A. Stasny within larger groups. Today the following three families are believed to belong to superfamily Eriophyoidea: * Eriophyidae Nalepa, 1898 * Phytoptidae Murray, 1877 * Diptilomiopidae Keifer, 1944 The group is ancient, with forms with two pairs of legs, already similar to the modern ones being found in Triassic amber from Italy: '' Ampezzoa,'' '' Triasacarus,'' '' Minyacarus'' and '' Cheirolepidoptus,'' which were specialised on extinct conifers belonging to the family Cheirolepidiaceae. The four genera were subsequently placed in a new extinct clade, the Triasacaroidea, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Demodex
''Demodex'' is a genus of tiny mites that live in or near hair follicles of mammals. Around 65 species of ''Demodex'' are known. Two species live on humans: ''Demodex folliculorum'' and ''Demodex brevis'', both frequently referred to as eyelash mites, alternatively face mites or skin mites. Different species of animals host different species of ''Demodex''. ''Demodex canis'' lives on the domestic dog. The presence of ''Demodex'' species on mammals is common and usually does not cause any symptoms, although occasionally some skin diseases can be caused by the mites. ''Demodex'' is derived from Greek δημός ''dēmos'' "fat" and δήξ ''dēx'', "woodworm". Notable species ''D. folliculorum'' and ''D. brevis'' ''D. folliculorum'' and ''D. brevis'' are typically found on humans. ''D. folliculorum'' was first described in 1842 by Simon; ''D. brevis'' was identified as separate in 1963 by Akbulatova. ''D. folliculorum'' is found in hair follicles, while ''D. brevis'' lives in seb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider Mite
Spider mites are members of the Tetranychidae family, which includes about 1,200 species. They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants, where they may spin protective silk webs, and they can cause damage by puncturing the plant cells to feed. Spider mites are known to feed on several hundred species of plants. Description Spider mites are less than in size and vary in color. They lay small, spherical, initially transparent eggs and many species spin silk webbing to help protect the colony from predators; they get the "spider" part of their common name from this webbing. Life cycle Hot, dry conditions are often associated with population build-up of spider mites. Under optimal conditions (approximately 27 °C), the two-spotted spider mite can hatch in as little as 3 days, and become sexually mature in as little as 5 days. One female can lay up to 20 eggs per day and can live for 2 to 4 weeks, laying hundred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...
