Rabbit ear mite

Important notice: Psoroptes cuniculi is an ectoparasite affecting animals, not plants. It is not an agricultural crop pest; instead, it is a significant veterinary pathogen known for causing psoroptic mange in domestic rabbits and various other mammalian species.

Taxonomically, this organism belongs to the class Arachnida, order Sarcoptiformes, and family Psoroptidae. Unlike phytophagous pests, these mites are obligate parasites that dwell within the ear canal, feeding on skin secretions, lymph, and tissue debris, which triggers a severe inflammatory response in the host.

The life cycle of this mite takes place entirely on the host and encompasses the stages of egg, larva, two nymphal stages, and adult. Under favorable environmental conditions, such as high humidity and moderate temperatures, the entire life cycle can be completed in approximately 15 to 21 days, facilitating rapid spread within rabbit colonies.

The damage caused by these mites manifests as psoroptic mange, characterized by intense itching, crusting, and secondary bacterial infections within the ear canal. If left untreated, the infestation can progress to the middle and inner ear, leading to neurological complications, loss of balance, and, in severe cases, the death of the animal.

Control and management strategies include:

• Regular physical inspection of rabbits' ears for crusts or discharge.
• Administration of approved acaricides, such as selamectin, ivermectin, or specialized ear drops.
• Strict sanitation protocols for cages and equipment using appropriate disinfectants.
• Isolating infected individuals to prevent transmission between rabbits.
• Quarantining new stock before introducing them into the main population.
