The bacteria adhered to the silkworm house during silkworm rearing can easily infect the silkworm body of the next season and cause the occurrence of silkworm disease. Therefore, sterilization after the end of breeding becomes more important. Sericultural farmers must strictly follow the “one-scrape, two-sweep, three-wash, four-elimination, and five-smoke†procedures for disinfection at the end of each season. The main steps are:
1. Thoroughly clean the surrounding environment of the silkworm room, the storage mulberry room, the cluster tools, the silkworm worm, and the silkworm wormhouse. The scavenging matter and the silkworm silkworm excrement must be buried and buried and limed.
2. Put the clusters on top of the flame and burn them quickly to remove the filaments from the clusters.
3. Take the silkworms out of the outdoor cleaning and exposure to sunlight, and open the silkworm room to be fully exposed to the air.
4. Put silkworms into the silkworm room, close the doors and windows with 2% sulphur fume or formalin for closed fumigation 1-2 times.
5. Disinfect the silkworm room furniture and wall surface again with bleaching powder or lime slurry containing 1-1.2% of available chlorine, and consolidate the disinfection.
