Trichotriids
Trichotriidae are a family of microscopic mites belonging to the order Sarcoptiformes. While often overlooked due to their small size, they act as significant pests in various agricultural environments, particularly affecting the health of crops grown in high-humidity conditions such as greenhouses and nurseries.

Trichotriids
The biology of these mites is intrinsically linked to moisture and organic decomposition. They thrive in damp substrates and on plant surfaces where fungal hyphae are present, as they often graze on both plant tissues and associated fungal colonies found in the rhizosphere or on foliage.
The economic impact of Trichotriidae is mainly observed through the weakening of young plants and seedlings. By feeding on the epidermal cells of leaves and stems, they cause physiological stress that manifests as stunted growth, chlorosis, and the distortion of developing tissue, which significantly lowers plant vitality.
Beyond direct feeding damage, these mites act as vectors for various plant pathogens. By moving across the canopy, they facilitate the spread of fungal spores from diseased to healthy plant tissues, effectively acting as an accelerant for outbreaks of secondary diseases that can destroy entire crop batches.
Effective management and control of Trichotriidae involve a multi-faceted approach focused on cultural and chemical interventions:
- Maintaining proper ventilation in greenhouses to lower excess humidity.
- Implementing strict sanitation protocols to remove debris and dead plant matter.
- Monitoring irrigation practices to prevent water stagnation in the growing medium.
- Applying specific acaricides targeted at mites when monitoring indicates population growth.
