Knemidokoptes mites
The family Knemidokoptidae belongs to the order Sarcoptiformes. These are microscopic burrowing mites that function as obligate parasites of birds. They do not pose a threat to agricultural crops; instead, they focus on the epidermis of domestic and wild birds, leading to debilitating conditions known as knemidocoptiasis.

Knemidokoptes mites
The biology of these mites is characterized by a life cycle that occurs entirely on the host bird. The females burrow into the stratum corneum of the skin to lay eggs. By feeding on lymph, tissue fluids, and skin cells, they create optimal conditions for rapid population growth, especially in high-density poultry housing environments.
Damage typically manifests as proliferative, sponge-like or chalky crusts on non-feathered parts of the bird, such as the beak, legs, and skin around the eyes. Infested birds experience severe itching and irritation, which can lead to permanent deformities of the beak and claws, causing physical pain and difficulties in foraging.
The economic impact of these mites on poultry farms is significant due to decreased productivity. Infested birds show reduced growth rates, lower egg production, and increased susceptibility to secondary bacterial infections. The mites are easily transmitted through contaminated bedding, equipment, or direct bird-to-bird contact.
Effective control measures include:
- Routine application of acaricides within the poultry facilities.
- Implementation of strict quarantine protocols for any new birds introduced to the flock.
- Treatment of infested birds using specialized veterinary acaricidal medication.
- Maintaining rigorous sanitation standards and cleanliness in housing areas.
