Allergic rhinitis due to house dust mite

Allergic rhinitis due to house dust mite (ICD-11 CA08.02): perennial IgE-mediated nasal allergy to Dermatophagoides mite fecal allergens such as Der p 1, affecting 65–130 million people, treated with pharmacotherapy and sublingual immunotherapy.

Cecidophyopsis ribis

Cecidophyopsis ribis (Westwood, 1869), the blackcurrant gall mite or currant bud mite, is an eriophyid mite pest of Ribes nigrum that galls buds and vectors blackcurrant reversion virus; controlled mainly by the Ce resistance gene and sulphur acaricides.

Cheese mite

The cheese mite is a storage mite, chiefly Tyrolichus casei and Acarus siro, that infests cheese and is deliberately used to ripen Milbenkäse and Mimolette.

Demodex

Demodex is a genus of microscopic mites living in human hair follicles and sebaceous glands; D. folliculorum and D. brevis are permanent human ectoparasites, near-universal in adults, linked to rosacea, demodicosis, and Demodex blepharitis, treated with lotilaner 0.25% (XDEMVY).

Demodex folliculorum

Demodex folliculorum, the human follicle mite (with Demodex brevis), a 0.3–0.4 mm commensal eyelash mite; overgrowth causes blepharitis and rosacea, treated with tea tree oil, ivermectin, and lotilaner 0.25%.

Dermanyssus gallinae

Dermanyssus gallinae, the poultry red mite or chicken mite, is a nocturnal blood-feeding mite of birds hiding in poultry-house cracks; completes its life cycle in as few as 7 days, survives months without feeding, and shows widespread acaricide resistance.

Diagnosis and treatment of human mite infestations

Diagnosis and treatment of human mite infestations covers how scabies and other mite conditions are confirmed by scraping or dermoscopy and treated with permethrin or ivermectin.

Dust mite allergy

Dust mite allergy, also called dust allergy, is a hypersensitivity to proteins from house dust mites in bedding and carpeting, causing perennial rhinitis, asthma, or atopic dermatitis.

Effects of Varroa mites on honey-bee colonies

Varroa mites (Varroa destructor) kill honey-bee colonies mainly by vectoring viruses, above all deformed wing virus; untreated colonies die within one to four years, driving US winter losses averaging 28.7% since 2006.

Feather mite

Feather mites are mites that live permanently on the feathers and skin of birds, feeding on fungi, bacteria, preen oil, and debris. About 2,500 species are described, mostly harmless.

Gamasoidosis

Gamasoidosis, also called bird mite disease or fowl mite dermatitis, is human dermatitis from gamasid mite bites, chiefly Dermanyssus gallinae, the nocturnal poultry red mite that also bites people via nests and poultry houses.

House dust mite

House dust mite (Dermatophagoides pteronyssinus, D. farinae) is a humidity-dependent domestic arachnid whose fecal allergens Der p 1 and Der p 2 drive asthma and rhinitis; controlled trials show avoidance measures give little clinical benefit, while immunotherapy is disease-modifying.

Mites affecting humans

Mites affecting humans are small arachnids, from the burrowing scabies mite to house dust and storage mites, that cause itchy skin, asthma, and diseases such as scrub typhus.

Mold mites

Mold mites are small pale mites, chiefly Tyrophagus species, that feed on mold in damp homes and stored foods, multiplying rapidly above 65% relative humidity.

Ornithonyssus

Ornithonyssus is a genus of Macronyssidae blood-feeding mites including the northern fowl mite (O. sylviarum), tropical fowl mite (O. bursa), and tropical rat mite (O. bacoti), permanent ectoparasites of birds and rodents with 5-12 day life cycles.

Ornithonyssus sylviarum

Ornithonyssus sylviarum, the northern fowl mite (Macronyssidae), is a permanent blood-feeding ectoparasite of birds and the main poultry mite pest in North America, completing its 5-12 day life cycle on the host and reducing egg production.

Peptidase 1 (mite)

Peptidase 1 (mite), or Der p 1, is the major papain-like cysteine protease allergen of Dermatophagoides pteronyssinus feces; over 80% of house dust mite-allergic patients are sensitized, and it anchors diagnosis, exposure measurement, and immunotherapy dosing.

Pyemotes tritici

Pyemotes tritici, the straw itch mite (family Pyemotidae), is a cosmopolitan 0.2 mm ectoparasitoid of stored-grain and wood-boring insects with a 4-7 day viviparous life cycle; its bites cause itchy pustular dermatitis in humans.

Sarcoptes scabiei

Sarcoptes scabiei, the human itch mite (var. hominis), is a skin-burrowing arachnid causing scabies and, in animals, sarcoptic mange; four life stages, 0.3-0.45 mm females, treated with permethrin or ivermectin.

Stored-food and grain mite dermatitis

Stored-food and grain mite dermatitis is skin inflammation caused by mites infesting grain, flour, and hay, producing occupational rashes such as grocer's itch, copra itch, and straw itch.

Syringophilidae

Syringophilidae, the quill mites, are permanent obligate mite ectoparasites living inside bird feather quills; two subfamilies, about 400-417 described species, high host specificity, all regions except Antarctica.

Tetranychus evansi

Tetranychus evansi, the red tomato spider mite (also Tetranychus takafujii), is a South American tetranychid mite and invasive EPPO A2 pest of Solanaceae, suppressing tomato plant defences and causing up to 90% tomato yield losses in Africa.

Tetranychus urticae

Tetranychus urticae, the two-spotted or red spider mite, is a 0.25-0.5 mm polyphagous mite pest of over 1,000 plant species, with a 7-day to 3-week life cycle and record acaricide resistance (96 active ingredients).

Trombiculosis

Trombiculosis (trombiculiasis, chigger dermatitis): pruritic skin inflammation from larval trombiculid mite feeding via a salivary stylostome; Leptotrombidium chiggers also transmit scrub typhus.

Varroa

Varroa is a genus of parasitic mites, whose species Varroa destructor is the most damaging parasite of the western honey bee and a leading cause of colony losses worldwide.
