Back to Mountain Disinfection of Comprehensive Prevention and treatment of Silkworm Disease
The silkworms were disinfected after finishing. Because silkworms are cocooned and many rotten cocoons, diseased silkworm corpses and feces are left after cocoon collection, especially in summer and autumn, when pathogens are most concentrated, if disinfection is not carried out in time, it will pose a great threat to the safety of later batch silkworms. Therefore, a disinfection must be carried out in time and seriously, which is generally called "back to the mountain disinfection" in production. The main method is to gather all kinds of silkworm utensils used by @ # @ 250 silkworms @ and the silkworms used on the silkworms, first spray and disinfect them with 1% murine 2% lime paste or 1% available chlorine bleach solution, and then clean and clean the silkworm silkworm rooms and silkworm rooms, which can reduce the chance of pathogen spreading pollution and help to continue to raise silkworms in the next period.

The cultivation of queen bees: the natural alternation of King Tai and King Yu
Select the excellent colony with the old queen bee as the population, when they build the alternate king platform, put the nest spleen with the natural king platform in the relay box, put the unsealed lid spleen on both sides, and add a king partition board between the nest box and the successor box to limit the queen bee to the nest box and record the date of the birth of the queen bee in each natural king platform. The natural alternating king platform can be extracted from this old king group one after another, and the natural alternating queen bee can make the good characters of the population more stably inherited. When this kind of natural alternation occurs, the bee colony generally builds only a few queens, and the quality of the queen bee is compared.

What should you pay attention to when buying scorpion?
1. When buying scorpion, you should go to those scorpion farms that are well-known, have a long history of breeding and have a large scale, and check the business license or honorary certificate granted by the relevant unit in the industrial and commercial department. Do not buy blindly for the sake of being cheap or saving road fares. 2. Check the number of scorpions in the donor unit before buying scorpions. If there are more big scorpions than young scorpions in the breeding unit, it is likely to be a scorpion dealer. The proportion of scorpions in normal farms should be about 1:30. Second, check the number of Tenebrio Molitor in the breeding unit.
