Flour Mite
The flour mite, ''Acarus siro'', a pest of stored grains and animal feedstuffs, is one of many species of grain and flour mites. An older name for the species is ''Tyroglyphus farinae''. The flour mite, which is pale greyish white in colour with pink legs, is the most common species of mite in foodstuffs. The males are from long and the female is from long. The flour mites are found in grain and may become exceedingly abundant in poorly stored material. The female produces large clutches of eggs and the Biological life cycle, life cycle takes just over two weeks. The cast skins and dead bodies can form a fluffy brown material that accumulates under sacks on the warehouse floor. After a while, predatory mites tend to move in, and these keep the flour mites under control. Flour mites that contaminate grains, flour and animal feedstuffs, create allergens in the dust produced, and also transfer pathogenic microorganisms. Foodstuffs acquire a sickly sweet smell and an unpalatable t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trombicula Autumnalis
''Neotrombicula autumnalis'', known as the harvest mite or autumn chigger, is a species of mite of the family Trombiculidae. Their larvae live parasitically; they infect all domestic mammals, humans, and some ground-nesting birds. Description The larvae are normally orange or red with six legs, but develop eight legs by nymph stage. The larvae are up to in size, with adult mites about long. Lifecycle The eggs are laid in damp soil. After hatching, the larvae climb blades of grass and wait for a potential host. With their "blade-like chelicerae The chelicerae () are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or similarly ...", they attach themselves to the hosts and feed on their tissues. After sucking, which lasts several days, they fall off and develop over three stages of nymph to adult mites. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trombicula Alfreddugesi
''Trombicula alfreddugesi'', also called ''Eutrombicula alfreddugesi'', is a species in the genus ''Trombicula''. (''Eutrombicula'' is a subgenus of mites in ''Trombicula'' of the family Trombiculidae.) It is the common chigger species of the United States, also sometimes called the harvest mite. Chiggers are the parasitic larval stages of these free-living mites. They are rarely seen in the dry Western states because the species prefers humid climates. '''' online, retrieved 10 August 2011: "occurs from the Atlantic coast to the Midwest and southward to Mexico". They are commonly found in undergrowth and grassy ...

Scabies
Scabies (; also sometimes known as the seven-year itch) 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 usually develops 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. Scabies is caused by infection with the female mite '' Sarcoptes scabiei ''var.'' hominis'', an ectoparasite. The mites burrow into the skin to live and deposit eggs. The symptoms of scabies are due to an allergic reaction to the mites. Often, only betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcoptes Scabiei
''Sarcoptes scabiei'' or the itch mite is a parasitic mite that burrows into skin and causes scabies. The mite is found in all parts of the world. Humans are not the only mammals that can become infected. Other mammals, such as wild and domesticated dogs and cats (in which it is one cause of mange) as well as ungulates, wild boars, bovids, wombats, koalas, and great apes are affected. The Italian biologists Giovanni Cosimo Bonomo and Diacinto Cestoni showed in the 17th century that scabies is caused by ''Sarcoptes scabiei''; this discovery of the itch mite in 1687 marked scabies as the first disease of humans with a known microscopic causative agent. The disease produces intense, itchy skin rashes when the impregnated female tunnels into the stratum corneum of the skin and deposits eggs in the burrow. The larvae, which hatch in three to 10 days, move about on the skin, moult into a nymphal stage, and then mature into adult mites. The adult mites live three to four weeks in t ...

Pyemotes Herfsi
''Pyemotes herfsi'', also known as the oak leaf gall mite or itch mite, is an ectoparasitic mite identified in Western Canada in 1923 and subsequently found in India, Asia, and the United States. The mite parasitizes a variety of insect hosts and bites humans, causing red, itchy, and painful wheals (welts). The mites are barely visible, measuring about 0.2–0.8 millimeters; their great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid. Life cycle Newly emerged and mated females inject a neurotoxin-containing saliva into their hosts, which paralyzes the host and enables the gravid female mites to feed on the host's hemolymph. The posterior portion (opisthosoma) of the female enlarges as its progeny develops inside, and, within a few days, up to 250 adult mites emerge from the gravid female. Bruce and Wrensch (1990) found that progeny of the straw itch mite averaged 254 offspring of which 92% were females. Males em ...

Psoroptidae
Psoroptidae is a family of parasitic mites, which are long and live on the surface of the skin, rather than burrowing into it. These mites affect various species, including cats, dogs, rabbits, cattle, sheep, and horses, causing skin inflammation, scabs, crusting, and hair loss. The following genera are within the family Psoroptidae: * ''Psoroptes'' * '' Chorioptes'' * '' Otodectes'' See also * List of mites associated with cutaneous reactions Many mites can bite human skin and cause cutaneous reaction and/or disease.

Ornithonyssus Sylviarum
''Ornithonyssus sylviarum'' (also known as the northern fowl mite) is a haematophagous ectoparasite of poultry. In both size and appearance, it resembles the red mite, ''Dermanyssus gallinae''. This blood-feeding parasite is broadly distributed, and has been reported on 72 host species of North American birds in 26 families. The mites have been a major pest of the poultry industry since the early 1900s.

Ornithonyssus Bursa
''Ornithonyssus bursa'' (also known as the tropical fowl mite) is a species of mite. It is most often a parasite of birds, but also has been found to bite humans and two species of mammals. It usually lives in birds' feathers, but for laying its eggs, it more often uses their nests rather than their feathers. Tropical fowl mites undergo five stages during their development: egg, larva, protonymph, deutonymph, and adult. During the last two stages, they suck blood from their host for food. They are often diurnal, whereas northern fowl mites are nocturnal in nature. Synonyms ''Ornithonyssus bursa'' has been described under the following synonyms, which are no longer used: * ''Leiognathus bursa'' Berlese (1888) * ''Liponyssus bursa'' Hirst (1916) * ''Ornithonyssus bursa'' Sambon (1928) Description ''Ornithonyssus bursa'' has four pairs of legs, three of which are located on the sternal plate. Towards its posterior end, its body narrows slightly. These two features distinguish it f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
