Rhinonyssids
The family Rhinonyssidae belongs to the order Mesostigmata. It is crucial to clarify that these organisms are not agricultural plant pests. They are obligate endoparasites found exclusively in the respiratory tracts, specifically the nasal passages and sinuses, of birds.

Rhinonyssids
In terms of taxonomy, rhinonyssids are part of the Dermanyssoidea superfamily. Their entire life cycle, from egg to adult, takes place within the host. Because they are biologically adapted as hematophagous parasites of vertebrates, they lack any mechanism to damage, feed on, or interact with botanical tissues.
The biological cycle involves rapid development within the host's nasal cavity. Transmission occurs primarily through direct physical contact between birds, often during feeding or communal roosting. Once inside, they feed on mucosal secretions and blood, leading to chronic respiratory distress in infested birds.
Their economic impact is strictly limited to the poultry industry. In infested birds, the parasites cause decreased productivity, stunted growth, and susceptibility to secondary infections, which can lead to severe losses for poultry farmers. They pose zero threat to crops, greenhouses, or ornamental plants.
Management strategies focus on veterinary health and biosecurity within poultry facilities to prevent the spread of the parasite:
- Routine screening of bird flocks for respiratory issues.
- Implementing strict quarantine protocols for new stock introductions.
- Using veterinary-approved acaricides to disinfect housing environments.
- Maintaining high standards of poultry hygiene to minimize transmission opportunities.
