Pygmephorus is a genus of large mites, in the family Pygmephoridae. [1]
Scabies is a contagious skin infestation by the mite Sarcoptes scabiei. The most common symptoms are severe itchiness and a pimple-like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person will usually develop symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children. The itch is often worse at night. Scratching may cause skin breakdown and an additional bacterial infection in the skin.
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops.
Mites are small arachnids.
The Acari are a taxon of arachnids that contains mites and ticks. The diversity of the Acari is extraordinary and their fossil history goes back to at least the early Devonian period. Acarologists have proposed a complex set of taxonomic ranks to classify mites. In most modern treatments, the Acari are considered a subclass of the Arachnida and are composed of two or three superorders or orders: Acariformes, Parasitiformes, and Opilioacariformes; the latter is often considered a subgroup within the Parasitiformes. The monophyly of the Acari is open to debate, and the relationships of the acarines to other arachnids is not at all clear. In older treatments, the subgroups of the Acarina were placed at order rank, but as their own subdivisions have become better understood, treating them at the superorder rank is more usual.
The marsh shrew, also known as the Pacific water shrew, Bendire's water shrew, Bendire's shrew and Jesus shrew is the largest North American member of the genus Sorex. Primarily covered in dark-brown fur, it is found near aquatic habitats along the Pacific coast from southern British Columbia to northern California. With air trapped in its fur for buoyancy, marsh shrews can run for three to five seconds on top of the water. It measures about 16 cm (6.3 in) in length, including a 7-centimetre (2.8 in)-long tail, and weighs an average of 14.5–16 g (0.51–0.56 oz). The marsh shrew's diet consists mainly of invertebrates, which it hunts on land and in the water. They are rare; their populations are thought to be in decline, and they are considered endangered in parts of their range.
Potyviridae is a family of positive-strand RNA viruses that encompasses more than 30% of known plant viruses, many of which are of great agricultural significance. The family has 12 genera and 235 species, three of which are unassigned to a genus.
Acaricides are pesticides that kill members of the arachnid subclass Acari, which includes ticks and mites. Acaricides are used both in medicine and agriculture, although the desired selective toxicity differs between the two fields.
Varroa is a genus of parasitic mites associated with honey bees, placed in its own family, Varroidae. The genus was named for Marcus Terentius Varro, a Roman scholar and beekeeper. The condition of a honeybee colony being infested with Varroa mites is called varroosis.
An EPPO code, formerly known as a Bayer code, is an encoded identifier that is used by the European and Mediterranean Plant Protection Organization (EPPO), in a system designed to uniquely identify organisms – namely plants, pests and pathogens – that are important to agriculture and crop protection. EPPO codes are a core component of a database of names, both scientific and vernacular. Although originally started by the Bayer Corporation, the official list of codes is now maintained by EPPO.
Cheyletiella is a genus of mites that live on the skin surface of dogs, cats, and rabbits.
Opilioacariformes is the smallest order of mites, containing a single family, and around 10 genera. They are rare, large mites, and are widely considered primitive, as they retain six pairs of eyes, and abdominal segmentation. Opilioacariformes may be the sister group to the Parasitiformes.
The Guadeloupe big-eyed bat is a species of bat in the family Phyllostomidae. It is found in Guadeloupe and Montserrat. It is threatened by habitat loss mostly because of Hurricane Hugo, which destroyed 90% of the population of this bat in 1989. The species may be locally extinct in some areas of Guadeloupe.
Psoroptes is a genus of mites, including the agents that cause psoroptic mange.
Trombiculidae are a family of mites. Chiggers are often confused with jiggers - a type of flea. Several species of Trombiculidae in their larva stage bite their animal or human host and by embedding their mouthparts into the skin causing "intense irritation" or "a wheal, usually with severe itching and dermatitis",
Karyolysus is a genus of coccidia. With the exception of K. sonomae whose vertebrate host is the yellow-legged frog, species in this genus only infect lizards of the genus Lacerta.
Rhinonyssidae is a family of mites in the order Mesostigmata.
Iris adriatica is a plant species in the genus Iris, it is also in the subgenus Iris. It is a rhizomatous perennial, from the Dalmatia region of Croatia in Europe. It has short sickle shaped leaves, small stem and flowers that vary from yellow to purple or violet. It is rarely cultivated as an ornamental plant in temperate regions.
Belba is a genus of mites belonging to family Damaeidae. The genus was established by Carl von Heyden in 1826. Notaspis corynopus was the type species. Species that are part of the genus can be found in Eurasia and North America.
Pygmephorus lutterloughae is a species of large mites, in the genus Pygmephorus. It was described from a sample in the National Museum of Natural History collection, collected in Oregon in 1970 and is named after Sophie Lutterlough.
The Pygmephoridae are a family of mites, in the order Trombidiformes.
