Tyrophagus
Oudemans, 1924
Tyrophagus is a of in the , containing at least 17 described . The genus includes economically significant pests such as Tyrophagus putrescentiae (the mould mite or cheese mite) and T. neiswanderi, which infest stored products, ornamental plants, and laboratory cultures. Several species are known to disseminate and bacteria, causing damage in tissue culture facilities and food environments. Members of this genus exhibit rapid growth under favorable conditions, with times of approximately 29 days and high reproductive rates.

Habitat
Stored products; tissue culture laboratories; ornamental plants; culture conditions with associated . Specific associations vary by : T. putrescentiae commonly occurs in stored food products and laboratory settings, while T. neiswanderi has been documented on ornamental plants.
Distribution
Recorded from Rica (Central Valley); Denmark; Norway; Sweden; British Isles (Great Britain). Broader distribution as stored product pests is implied but not explicitly documented in available sources.
Diet
, including Leptosphaerulina sp. (documented as food source for T. putrescentiae in laboratory culture). Diet likely varies by and ; stored product species presumably feed on moulds and debris.
Host Associations
- Leptosphaerulina sp. - food sourceAssociated used in laboratory rearing of T. putrescentiae
- ornamental plants - T. neiswanderi and T. putrescentiae documented as pests of ornamental plants
- fungi - T. putrescentiae disseminates in tissue culture laboratories
- bacteria - T. putrescentiae disseminates bacteria in tissue culture laboratories
Life Cycle
(4.52–4.54 days) → (1.44–1.57 days) → (1.31–1.37 days) → tritonymph (1.29–1.45 days) → . Pre- period: 1.86 days; oviposition period: 7.21 days; post-oviposition period: 1.35 days. time: 29.47 days. Data derived from laboratory studies of T. putrescentiae; field may differ.
Behavior
Rapid multiplication: T. putrescentiae can multiply its initial population in a single day under favorable laboratory conditions, leading to population explosions. Disseminates and bacteria in tissue culture environments.
Ecological Role
Pest of stored products and ornamental plants; biological for fungal and bacterial dissemination in laboratory and agricultural settings. Serves as for predatory such as Blattisocius mali.
Human Relevance
Economic pest in food and tissue culture facilities. T. putrescentiae known as the cheese or mould mite. Potential target for using predatory mites.
