Psorergatid mites

The host range of psorergatids is quite specific. They most frequently infest sheep, cattle, and rodents. In the context of the agricultural sector, they cause economic damage to livestock farms, as the parasitization of these mites leads to the degradation of product quality, particularly wool, making them indirectly significant for the agricultural industry.

The biology of these parasites is closely tied to the condition of the host's skin epidermis. The life cycle includes egg, larva, protonymph, deutonymph, and adult stages. The mites feed on lymphatic fluid, penetrating the superficial skin layers. The entire development cycle occurs directly on the animal's body, which complicates control efforts in the external environment.

The nature of the damage manifests as chronic itching, skin dryness, and the formation of characteristic scales. In sheep, this leads to severe damage to hair follicles, wool loss, and decreased animal productivity. Constant skin irritation causes restlessness in livestock, which negatively affects overall weight gain indicators and the health status of the herd.

Protection measures include a set of veterinary and sanitary actions. To combat infestation, the following methods are used:

• Use of acaricidal baths for dipping animals.
• Application of modern insecto-acaricidal products directly to the skin (spot-on treatments).
• Strict adherence to quarantine protocols when acquiring new livestock.
• Regular disinfection of housing and equipment to prevent re-infestation.
