Disease relevance of Acaridae

• RESULTS: During 1986-1991, 1244 new cases of occupational rhinitis (474 women and 497 men) and 1867 new cases of occupational asthma (916 women and 951 men) were reported to the Register. Animal dander, flours, wood dusts, textiles, phthalic acid anhydrides and storage mites were important causes of occupational rhinitis [1].

High impact information on Acaridae

• Six sera were obtained from workers exposed to storage mites and with occupationally related lower respiratory tract symptoms [2].
• With the methods used, we could discriminate mite-allergic patients who were mainly sensitized to the major Der p allergens (Der p 1, Der p 2) from patients with a broad sensitization profile, including highly cross-reactive allergens (e.g. Der p 10: tropomyosin) as well as reactivity to storage mites [3].
• The prevalence of specific IgE to the storage mites Aleuroglyphus ovatus (Ao) and Chortoglyphus arcuatus (Ca) was studied in 77 individuals with allergic asthma and/or chronic allergic rhinitis [4].
• Lep d 1 was detected in 23% of samples and Lep d 1 levels were higher in the homes of patients sensitized to storage mites (Mann-Whitney P < 0.05), whereas this allergen was not detected in the homes of pollen-allergic patients [5].
• The risk of work related symptoms was associated with sensitisation to wheat or alpha-amylase, and with atopy, but not with sensitisation to storage mites, work seniority, or smoking habit [6].

Associations of Acaridae with chemical compounds

• Storage mites seem to be the most important allergen among grain elevator workers in Denmark [7].
• Acaricidal effect of a diatomaceous earth formulation against Tyrophagus putrescentiae (Astigmata: Acaridae) and its predator Cheyletus malaccensis (Prostigmata: Cheyletidae) in four grain commodities [8].
• Lardoglyphus falconidus n. sp. (Acarina: Acaridae) from the nest of an American kestrel (Falco sparverius L.) [9].
• The most important airborne substances include grain dust and its constituents, bacteria and metabolites (endotoxin), fungi and metabolites (glucan), and storage mites [10].
• The efficacy of benzyl benzoate sprays in killing the storage mite Tyrophagus putrescentiae (Acari: Acaridae) [11].

Gene context of Acaridae

• When densities of < 500 Caloglyphus berlesei (Michael) (Acarina: Acaridae) per 50 C. pumilio were provided, mite availability had a significant effect on dispersal of beetles captured with both black light traps and the mesh-bottomed trap during the day 1-3 period [12].
