Tyroglyphid mites
Tyroglyphid mites (Tyroglyphidae) represent a family of small acariform mites within the order Sarcoptiformes. These pests are primarily known for their destructive role in storage facilities, where they infest plant products, seeds, and bulbs, although they can also cause significant damage to young crops in fields under conditions of high soil moisture.

Tyroglyphid mites
These mites affect a wide range of agricultural products, including cereal grains, legumes, flour, dried fruits, and various vegetables like potatoes and flower bulbs. In agricultural settings, they are known to attack germinating seeds, which directly results in poor plant stands and stunted development of the seedlings.
The biology of these mites is characterized by rapid development and high adaptability. Their lifecycle includes the egg, larva, protonymph, deutonymph (hypopus), tritonymph, and adult stages. The hypopus stage is particularly important, as it serves as a resilient, survival-focused form that allows the mite to withstand extreme conditions and spread via other animals.
The damage caused by tyroglyphid mites involves the destruction of the seed embryo, rendering the grain non-viable for sowing. Beyond direct mechanical damage, these mites contribute to the rapid deterioration of stored goods by introducing odors and promoting the growth of secondary fungal and bacterial infections, leading to substantial economic losses.
Effective management and control strategies for tyroglyphid mites include the following practices:
- Maintaining strict temperature and moisture control in storage facilities (below 13% humidity).
- Implementing regular cleaning and disinfection of storage infrastructure and equipment.
- Using high-quality, pre-treated, and properly dried seeds for planting.
- Applying authorized acaricides or fumigants in storage areas when initial outbreaks are detected.
