Trombicula
''Trombicula'', known as chiggers, red bugs, scrub-itch mites, or berry bugs, are small arachnids (eight-legged arthropods) in the Trombiculidae family. In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching and trombiculosis. These relatives of ticks are nearly microscopic, measuring 0.4 mm (0.01 in) and have a chrome-orange hue. A common species of harvest mite in North America is '' Trombicula alfreddugesi''. The larval mites feed on the skin cells, but not blood, of animals. The six-legged parasitic larva feeds on a large variety of creatures, including humans, rabbits, wallabies, toads, box turtles, quail, and even some insects. After crawling onto their hosts, they inject digestive enzymes into the skin that break down skin cells. They do not actually "bite", but instead form a hole in the skin called a stylostome, and chew up tiny parts of the inner skin, thus causing severe irritation and swelling. ...

Harvest Mite
Trombiculidae (); commonly referred to in North America as chiggers and in Britain as harvest mites, but also known as berry bugs, bush-mites, red bugs or scrub-itch mites, 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 cause "intense irritation" or "a wheal, usually with severe itching and dermatitis". Trombiculidae live in forests and grasslands and are also found in the vegetation of low, damp areas such as woodlands, berry bushes, orchards, along lakes and streams, and even in drier places where vegetation is low, such as lawns, golf courses, and parks. They are most numerous in early summer when grass, weeds, and other vegetation are heaviest. In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching. These relatives of ticks are nearly microscopic, m ...

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 ...

Stylostome
The stylostome is a funnel- or channel-like structure formed in response to trombiculid mites. The formation is not caused by the mouthparts of the mites, because these mites do not have needle-like mouthparts as other hematophagous animals have been known to have, but have chelicerae, which only pierce the skin. The tube is formed by the digestive enzymes in the saliva, which are the same salivary secretions that break down cells and cause the surrounding tissue to harden. As the mite feeds longer, the saliva seeps further down, digesting more tissue and causing the stylosome to penetrate to lower layers of skin. Transmission of disease Normally, the bite mark causes local swelling or welts, but in more serious cases it causes dermatitis. The mite can be infected with a disease called scrub typhus in Asia and the Pacific and can transmit the disease by carrying saliva directly into the blood stream, but mites in North America have not been known to transmit Lyme disease, Rocky ...

Trombiculosis
Trombiculosis is a rash caused by trombiculid mites, especially those of the genus ''Trombicula'' (chiggers). The rash is also often known as chigger bites. Prevention Chiggers are commonly found on the tip of blades of grasses to catch a host, so keeping grass short, and removing brush and wood debris where potential mite hosts may live, can limit their impact on an area. Sunlight that penetrates the grass will make the lawn drier and make it less favorable for chigger survival. Chiggers seem to affect warm covered areas of the body more than drier areas. Thus, the bites are often clustered behind the knees, or beneath tight undergarments such as socks, underwear, or brassieres. Areas higher in the body (chest, back, waist-band, and under-arms) are affected more easily in small children than in adults, since children are shorter and are more likely than adults to come in contact with low-lying vegetation and dry grass where chiggers thrive. An exceptional case has been descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
