heat treatment

A good acaricidal effect can be obtained by shaking off bees with a metal net cage, heating in a special way and continuously rotating the net cage for 5 minutes at 465438 0℃. This physical method is more beneficial than chemical drugs to kill mites. But it is inconvenient in practical application and cannot be popularized in beekeeping production.

Characteristic application

Taking advantage of the characteristics that giant bee mites like drone rooms, a special drone room foundation was made to induce queen bees to lay drone eggs and hatch into drone larvae. After bee mites gather in the unmanned computer room, they are extracted and burned. This method can reduce the number of bee mites by 20-30%. In addition, drone nests are often cut off, and drone larvae and bee mites are removed to reduce the parasitic rate.

Drug treatment of mites

According to the characteristics of bee mites parasitic on bees and breeding in closed rooms, in order to achieve a thorough control effect, it is best to apply pesticides at a favorable time when the queen bee has not laid eggs in early spring and stops laying eggs in late autumn, and there is no cover on the spleen of the bee colony. There are many kinds of anti-mite drugs. This paper introduces the commonly used effective anti-mite drugs in China for selection in prevention and control.

First of all, the acaricide is attached to the carrier, which is not in direct contact with bee products and has no pollution to bee products.

Secondly, it is safe for bees, and has a good killing effect on the big bee mite, and the drug effect lasts for a long time. It can kill mites that leave home one after another, and the control effect is as high as 100%.

Third, it is convenient to use, saving labor and time. When it is necessary to control mites, the tablets can be hung on the nest and spleen together with the bee colony inspection, and there is no need to unpack them separately. Compared with other spraying drugs, the work efficiency can be improved by 5- 10 times. The drug has obtained the national patent, and it is the most ideal drug for controlling bee mites in China at present. In practice, it has been welcomed and praised by the majority of beekeepers, and has been widely popularized and applied throughout the country. The above three drugs are all produced by bee pharmaceutical factory of bee research institute, which supplies the needs of the whole country.

Fourth, spraying the bee spleen with Stemona Stemona decoction can cure bee mites, but Stemona Stemona is harmless to people and has the function of killing lice and insects. Formula 1: Stemona Stemona 20 g, 500 mL of white dry wine above 60 degrees. Stemona Stemona was soaked in wine for 7 days and sprayed with cold water with the soaking solution of 1: 1, every 6 days 1 time, 3-4 times in total, which is effective in treating large and small bee mites and nest worms.

Formula 2: Stemona Stemona 20 g, Melia azedarach (with pulp) 10, star anise 6, decocted in water to 200 mL, cooled to filter residue, and sprayed with bee spleen, with mist as the degree.

1, broken child killing method

Because bee mites are mainly parasitic on bees, it is the most favorable and critical period to kill bee mites in the period of natural abortion of bees.

The operation method is as follows: when the queen bee has not started to lay eggs, there are no sealed young bees in the colony, and the bee mites are mainly parasitic on the body surface of adult bees, choose an efficient and pollution-free drug to kill the hidden and parasitic bee mites completely.

2. Artificial isolation method. According to the biological characteristics that the bee mite can only survive for 1-2 days on adult bees, the bee mite died because it could not find a host for 2-3 days.

The specific method is as follows: firstly, isolate the sub-populations in the bee colony with the isolation plate, and transfer all the sub-populations in the nest box to the relay box (in order to let the bees enter and leave freely, a small nest door can be opened at the front end of the mite isolation plate) to supplement the empty spleen for the queen bee to lay eggs, and then replace the queen bee isolation plate with the mite isolation plate. When the sub-population was isolated for about 24 days, the bees in the relay box died because they could not get food and had no larvae as breeding places. The effective rate of killing mites by this method can reach over 90%.

3, hanging medicine fumigation method

Fix fumigation and acaricidal tablets, such as mites, between the second bee lanes of the bee colony with thumbtacks and hang them obliquely. The dosage is 2 strong bees and 1 weak bees, and 3 weeks is a course of treatment. Because fumigation and acaricide tablets have the function of long volatilization duration, they can kill bees and mites that leave the house one after another, and the control effect is excellent, up to 100%. In this way, it is only necessary to hang the tablets on the nest spleen without unpacking when checking the bee colony. Compared with the smoke spraying method, the working efficiency can be improved by 5- 10 times.

4. Use bee spraying method

Firstly, contact acaricide, such as acaricide 1, is made into liquid medicine, and 300-600 ml of water (about 5 ml for each honeycomb spleen) is added to each milliliter of the medicine, fully stirred, put into a sprayer, and evenly sprayed on bees with honeycomb spleen (sprayed on the surface of bees).
