How to deal with black bees among beehives

If there is black bee disease in a dense bee colony, it can easily spread to other normal bees. First of all, the bee colony must be well prevented and controlled, otherwise the entire bee colony will be infected with black wind disease. When bees with black bee disease are found, they must be removed in time. Carry out eradication, because the black bee disease is very contagious, it is necessary to discover it in time and control it as early as possible to reduce losses.

Causes of honey bee black bee disease

Bee paralysis virus is transmitted to healthy bee colonies through nest building, replacement of honeycombs, and use of sick colonies to raise queens. It can also be caused by excessive rain, excessive humidity in the beehive, or prolonged drought and dry climate. Healthy bees can also become sick through contact with infected bees and eating contaminated feed.

Symptoms of black bee disease

Because the nerve cells of honeybees are directly damaged by the virus, the diseased bees suffer from paralysis and spasm, slow movement, constant twitching and trembling, and loss of flying ability. They stretch out their wings and legs, flap their wings weakly, and crawl powerlessly. Some have swollen abdomens, while others have thin bodies. They are often driven out of the hive by healthy bees. In the later stages, their body surface turns black, their fluff falls off, and their abdomens shrink, as if they had been fried.

Prevention and treatment of honey bee black bee disease

1. Improve the bee colony's own resistance: select disease-resistant and disease-tolerant bee species, and choose healthy and disease-free bee colonies to breed queen bees. When there is a lack of nectar and pollen sources in nature, it is necessary to supplement feeding in a timely manner and provide a certain amount of protein feed to strongly reduce the risk of disease.

2. Deal with sick bees in a timely manner: Check the activities of bees regularly. If any bees are found to show symptoms of paralysis, they should be eliminated immediately to prevent the paralysis from spreading to healthy bees.

3. Prevent bees from eating contaminated feed: feed bees with high-quality, pollution-free feed. If the nectar-producing plants have been contaminated, you must quickly move away from the source of contamination. At the same time, we must strengthen the insulation of the beehive to prevent the bee colony from getting damp.

4. Replace the beehive with a clean new one: The beehive should be disinfected regularly, about once every 6 days. The method is to use about 10 grams of sublimated sulfur powder and sprinkle it evenly on the frame beams, the nest entrance and the box entrance.

5. Spray the spleen with medicine: add 200,000 units of neomycin or chloramphenicol to 1 kg of syrup, shake well and spray it on the bee spleen. Spray once every 2 days for 2 to 3 times in a row.

Summary: This is all I have to say about the prevention and control methods for honey bee black bee disease. Although a large number of bees will die after the onset of honey bee black bee disease, the harm can be controlled and the losses can be reduced as long as it is discovered in time and prevented and controlled effectively.
