There are insects in the bee's nest. What should I do if the pupa falls?

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. ② Application of biological characteristics

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.

③ 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.

(1) Fast acaricide: It is a new acaricide. Safe for bees. The experimental results showed that the lethal concentration was 205ppm, which was highly toxic to bee mites. All the bees sprayed with 25ppm mites were shot down within 4 hours, and the acaricidal effect reached 100%. The control concentration of bee colony is 0.65,438+0%, that is, each ampoule is diluted with 500 ml of water. In the non-honey-collecting period, bees spray after returning to their nests. Take medicine every other day 1 time, usually twice. If it is not thorough, you can use 1 time after 1 week.

(2) A new non-amidine acaricide: Diptera 1. It is safe for bees, the lethal concentration is 2 18.6ppm, and it is highly toxic to the big bee mite. When 25ppm bees are used to spray mites, the acaricidal effect is 100%. When the concentration of 0. 1.25% is used in the bee colony, that is, 0.5 ml of medicine per ampoule is diluted with 40 ml of water, and the bee body is sprayed evenly at night, once a week 1 time, twice in a row, the acaricidal effect can reach 1%. This medicine can not only kill mites on bees, but also kill bees in nests.

(3) "Mipopu" high-efficiency acaricide tablet: This drug is a new acaricide successfully developed by Bee Research Institute. It has high-efficiency killing effect on the big bee mite, simple and easy to use, fast and lasting killing mites, safe for bees and no residue. The application method is as follows: fix the tablets between the second bee lanes of the bee colony with thumbtacks, with 2 pieces of strong bee colony hanging obliquely, and 2 pieces of weak bee colony 1 tablet, with 3 weeks as a course of treatment.
