Mites Elk - a dangerous deer parasite
Mite elk (Lipoptena cervi) - common folkthe name of deer bloodsuckers. The females and males feed mainly on the blood of the cloven-hoofed deer family. In rare cases, it parasitizes foxes, wild boars, large cattle, dogs, birds, etc. It has nothing to do with true mites. People attack only when the population is much higher than the usual number. The cycle of development on man is not complete. The area of distribution is great, including Siberia and the countries of Scandinavia.
The size of an adult insect is about 3.5 mm. Coats brownish color, dense, leathery, shiny differs elk mite. The photos presented in the article demonstrate a strong flattening of the body and head. It has 8 eyes, of which 2 are very large, complex and 3 pairs are simple. Antennae, deeply located in the frontal depressions, almost do not go beyond the head. The oral apparatus works on a piercing-sucking type. Legs with thickened hips and asymmetrical claws. Wings developed, dense, transparent, with veins. The abdomen is elastic, the oviduct can greatly increase with "pregnancy".
The elk mites differ in live birth. The female lays a pre-pupal with a size of up to 4 mm. She hardens, moving to the stage of the puparium, falls to the ground and waits for suitable weather conditions to turn into a pupa. The birth of the next occurs after a decent amount of time, required for maturing it in the oviduct of the female, since they proceed in turn. The transition of the pupa into a winged form occurs from late summer to October.
The elk tick does not matter. Extraction lurks, sitting on the grass, trees or bushes. It attacks only during the day. Attracts their smell and the warmth of the future owner. Having fallen on it, the insect sheds its wings, breaking off them at the base, buries into the wool and proceeds to the meal. Eating an elk mite can up to 20 times a day, sucking in total about 2 mg of blood.
After 20 days of nutrition, there is a metamorphosis: the covers darken, the head is drawn, the muscles of the wings die, the sexual difference manifests, the mating begins. One host can host up to 1000 parasites. They live in pairs, the males are firmly attached to the females. The birth of the first puparium occurs 17 days after copulation, it turns out that the winged individual needs a month to start producing the like. A female with a good diet can give birth to 30 pre-pups, from October to March. The tick elk in the wingless form is active all winter, ie about half a year, then it perishes.
With a large number of parasites, the animalhe experiences anxiety, loss of blood leads to exhaustion. At the site of bites, redness and papules are formed. The largest cluster of them occurs along the back and neck, i.e., in places where the wool is longer. Pollution by excrement strengthens skin inflammation. The elk tick is a carrier of many diseases. Studies have shown that more than a quarter of the winged deer bloodsucker had spirochetes.
People respond to the bites of a moose ticks differently. Some have itchy reddening, like mosquitoes, which take place within a week. In others, with reduced immunity, blisters, cramps, up to eczema, which can take months to heal, are formed.
