Glycyphagus domesticus

Definition

A species of stored-product mite in the family Glycyphagidae (order Sarcoptiformes), commonly known as the grocer's itch mite or house mite. This small, slow-moving astigmatid mite feeds on mold, fungi, and detritus in humid domestic and commercial environments, including grain stores, cheese ripening cellars, and bedding. Populations can proliferate rapidly under moist conditions, and heavy infestations may cause dermatitis or allergic reactions in humans handling infested materials. The species is cosmopolitan and frequently encountered in acarological surveys of food storage facilities and indoor air quality assessments.

Etymology

From Greek glykys (sweet) + phagein (to eat), referring to feeding habits, and Latin domesticus (of the house), indicating its association with human dwellings.

Example

Glycyphagus domesticus is often recovered from moldy grain residues in poorly ventilated silos, where its presence signals excessive moisture and potential spoilage conditions that also favor fungal growth.

Synonyms

• grocer's itch mite
• house mite

Related Terms

• Acari
• Sarcoptiformes
• Glycyphagidae
• stored-product pests
• astigmatid mites
• dermatitis
• Tyrophagus putrescentiae
• Lepidoglyphus destructor

Usage Notes

Distinguished from the more destructive grain mite Lepidoglyphus destructor by its smaller size and preference for moldier substrates; often found in mixed populations with Tyrophagus species. Not to be confused with house dust mites (family Pyroglyphidae), which occupy different ecological niches within dwellings. The common name "grocer's itch mite" refers to occupational exposure among food handlers.
