The ear mite in rabbits causes the development of ear scabies, psoroptosis.
Pathology is characterized by itching and the formation of scab-shaped animals in the auricle, combs lead to the appearance of wounds and the attachment of a secondary infection.
The disease is harmful to households: young animals infected with their mother often die, the weight and reproduction of breeding animals decreases, and the quality of the skin and meat deteriorates.
Treatment of a simple form is carried out with antiparasitic drugs; preventive measures are taken to prevent infection.
Psoriasis in rabbits. what an ear mite looks like
In rabbits, ear scabies provokes a skin mite. psoroptes cuniculi. The size of the parasite varies in the range of 0.5-0.9 mm, the body is yellow, sometimes with a shade of brown, has the shape of a rounded oval.
It is difficult to see ticks with the naked eye, it is better to use a magnifying glass
The jaws are long and strong which allows you to pierce the epidermis and suck out intracellular and tissue fluid. On the edges are 4 pairs of legs.
The insect lives in the auricle of a rabbit, moving and piercing the skin, damaging tissues, irritating nerve receptors with bristles on the legs, which causes severe itching.
The condition of the epidermis worsens the toxic substance that ticks secrete when they bite, causing an allergic reaction.
As a result, the skin in the ear becomes inflamed, local nutrition decreases, and recovery processes are disrupted.
Cells degenerate into keratinized scaly particles. Pathogenic organisms penetrate into the wounds, which provoke suppuration.
Important! Psoroptosis can occur at any time, but outbreaks of ear scabies in rabbits are observed mainly during periods of cooling.
All age groups are susceptible to the disease, more often the infection is detected in adults, less often young and rabbits are sick. Young animals become infected from the mother when the pathogen is transferred to the offspring from the rabbit’s ears.
How rabbits become infected with an ear tick, how it develops

Rabbit ear mite
- with close contact;
- through objects, bedding, feeders, clothes of the owner, inventory;
- when transplanting healthy rabbits into the room where sick individuals were kept.
In rare cases, cats or dogs that accidentally become infected in a dysfunctional household can bring insects to themselves.
Favorable factors for the development of the disease:
- tightness in the cell;
- rearrangement of animals;
Important! Hidden carriage plays a significant role in the spread of infection when adults and nymphs live in the outer ear of apparently healthy rabbits.
When an optimal environment arises to continue the cycle, arthropod parasites are activated, which causes an outbreak in the herd.
When penetrating the skin of the ear, mites begin to multiply actively, one female reproduces up to 60 eggs, which are glued to the skin scales with a uterine secret.
The further life cycle includes the following phases of development:
- Larva. Has 6 legs, leaves on average after 4 days. Shedding occurs in 2-3 days.
- Protonymph. This is the next stage nymph.
- Teleonymph. Preparatory stage for puberty.
- Imago Males become mature 2 days earlier than females.
With sufficient temperature and humidity, developmental periods for males are limited to 14 days, females mature in 16. The parasite lives on the skin of a rabbit for 2 months.
It is best to go to the veterinarian to confirm the diagnosis of Hrunya.ru. your irreplaceable assistant on the farm
Males create copulative pairs with female nymphs of the second phase, holding the insect with their legs. Fertilization occurs at the time of the female’s exit from the shell of the teleonymph.
Seed mites are a danger in the spread of the disease.
It is interesting! The duration of the transformation phases from an egg to an adult insect is determined by the temperature and humidity of the environment. At 35 ° C and low humidity, the life cycle is extended to 55 days.
Does itch mite live in rabbit’s ears?
In rabbits, cutaneous parasites are localized and multiply directly in the auricles, but sometimes creep out onto the body and stay there for some time, and then transfer to other animals.
Ticks are found on the skin of the neck and back, limbs with a strong spread, where they fall due to scratching.
It is interesting! It is assumed that attachment to the habitat on the hare-like body is associated with slight sweating in this area.

- small tuberous redness forms on the affected areas. the result of bites, then they turn into serous vesicles;
- after a day or two, the vesicles burst, a yellowish liquid flows out of them, forming grayish crusts upon drying;

If the symptoms are ignored, the auricle of the animal is covered with layers of scabs, sometimes they block the ear canal.
Pathological changes penetrate the eardrum, causing purulent inflammation. In advanced cases, the process goes to the neck, back, limbs.
Important! The final diagnosis is made by the veterinarian according to the results of microscopic studies of the material from the affected area. To independently detect the presence of a parasite, you need to carefully remove part of the crust and skin scales from the ear of a pet, put it on a glass plate, drip petroleum jelly.
