Viral bee paralysis

Viral bee paralysis: features, treatment, prevention.

Paralysis of bees – quarantine infectious disease, which can cause death in apiaries, a certain number of insects, and entire families. Pathogen infection – virus.

Bees disease can be of two types and split acute paralysis (that only adults suffer) and chronic (which are subjected to all members of the bee family).

Propagated virus in the cells of the body, Average intestine and nervous tissues of insects.

Etiology

Pathogens both forms, ie acute and chronic viral paralysis, have in common with each other serological relationship, with visible signs of the disease appear quite similar.

Often the disease manifests itself in the spring and summer, but can occur at any time. After wintering possible cases of paralysis due to too warm winter.

Summer heat helps to spread the disease and overheating hives, particularly after prolonged cold weather or rain.

At a temperature of up to 30 ° C usually observed development of acute paralysis, and in its rise to 35 Chronic ° C. The cause of the outbreak of infection may become insufficient supply of protein feed in early spring, ie cerago.

Then the bees begin to use “internal” white, which leads to a weakening of the body and increases the probability of hitting any insect infections.

In temperate zones may occur hidden (latent) infection, occurring without any visible signs.

Viral paralysis in bees feed is transmitted by contact, from patients to more fully healthy bees, through contaminated Slynn. Frequent, when both pathogen present in both insects.

Some individuals may not aching, and themselves be infected with HIV. Wandering drones and bees promotes contagion across the apiary, as permutation contaminated feed honeycomb beekeeper from one hive to another. Vector infection and is considered the varroa mite.

Signs of paralysis

Acute form of the disease tend young bee specimens. From the moment of infection to visible clinical manifestations of the disease is 4 to 15 days.

Visible signs look like:

1. bee disease affected not able to fly;
2. eyes jump around or near the hive;
3. spin in place;
4. sometimes small wings shaking sick bees
5. wings are asymmetrically (there raskrylytsya);
6. some individuals increased belly.
7. if you see the problem beehive, you can see on the bottom pidmor.

The clinical picture of chronic paralysis seen from 4 by 10 day of onset of disease.

It manifested the following features:

• first bees excitation and are in constant motion;
• some spinning gyroscope, notes small shake whole body or wings, raskrilitsya.
• individual patients can be assembled under the walls or bottom of the hive;
• then they lose the ability to fly;
• weaken and die on the spot;
• many reduced abdomen.

The characteristic feature of this disease can be considered as lost patient specimens hair, from which the affected bees outside look shiny and black.

Death occurs in 12-20 day after infection. The disease in different families paralysis can occur in different ways.

Sometimes it may happen, that the virus is killed whole bee family, Sometimes the disease affects only a certain number of bees.

But in this case the whole family greatly weakened slightly further develop, which affects productivity.

Immunity to viral paralysis of bees there, so there may be signs of relapse during the season.

All these symptoms are not specific, that refer only to this disease.

The final diagnosis is possible only after laboratory tests, held mandatory in suspected paralysis.

It also can not rule out other possible causes of death of bees: of protein deficiency, various kinds of toxicosis, Septicemia.

Treatment of paralysis

Manifestations of the disease itself subsides with the main tricks, but to treat paralysis bees must begin immediately, as soon as the diagnosis is confirmed.

Patients are recommended to change the uterus families, as it can be a source of infection for all.

Arrange a new hive and the bees give new uninfected feed.

Relaxer is advisable to strengthen the family sat, taking it from other family.

To effectively combat any form of paralysis virus used:

1. Endohlyukin. medicinal product, the active substance is endonukleoza, providing antiviral effect. Available in glass vials 50 mg. Snow. Before treatment drugs diluted in half a liter of water with 0,5 g activator (sold with it) which acts as magnesium chloride (or magnesium sulfate 62 g). The resulting composition irrigate seated between frames of bees. Number of treatments for medical purposes – from 3 to 5 intervals between them from week to 10 days.
2. Virusan. Available in powder form. The structure of the product include vitamins, minerals, amino acids, and garlic extract. It is used in the spring and early autumn for treatment and prevention viral infections bees. Pack content (40 g) dissolved in 10 l sugar syrup. fed by 1 liter at a time. To achieve the required effect 2-3 procedures with an interval between them 3 day.
3. Lozeval. Oily liquid yellow-brown color with a specific smell. Working solution for the treatment of one hive prepared from 0,3 liters of water and 5 ml drug. It is used three times, two days on the third. Irrigation is only possible at temperatures from + 18 WITH. Possible drug villa with syrup as feeding Before 3 times of the week interval.
4. pancreatic ribonuclease. solution with 15 ml of water and 50 ml water the bees patients at intervals of one week. Applies to four times.
5. Sanapin. One vial of medication used for the treatment of one hive. Sometimes the dose may be increased, if the disease progresses much. Before the procedure sealed the beehive. Ampoules Sanapin razdavlyvaetsya and a metal plate installed under the scope. After a half hour treatment is complete, further hive ventilated. Repeat the treatment if necessary conduct a week – two.

In addition to combat the paralysis of some beekeepers use of feeding biomitsin, oxytetracycline and pollination hives Biovit.

However, the use of antibiotics in the treatment of viral diseases is only possible in combination with antiviral drugs and more as a preventive measure to prevent other possible diseases, So, as bees body during this period severely weakened.

Prevention paralysis

The spread of any disease in the apiary undesirable. This not only disables bees, but also brings a lot of trouble beekeepers. Therefore, they should warn.

With preventive measures should adhere to the following:

• avoid overheating hives;
• feed bee protein food, if necessary;
• in time to change old females at younger and healthy;
• disinfected hives, frame and all equipment;
• in identifying patients bees isolate the whole family and treat it immediately;
• Feed stocks did not move from sick to healthy bees;
• better utilize the old frame, and cells – peretoplyuvaty;
• fight mites;
• use appropriate preventive drugs feeding in spring and autumn when medosbora.

Removes viruses are always very difficult. In fact, they can not completely destroy. Relaxer family may have bee disease survivors and keeps the remnants of the virus, even if externally it looks smoothly. Under certain adverse conditions possible recurrence of the disease.
