What are the prevention and control methods for silkworm bacterial diseases?

Livestock Farming 0 views
Silkworm bacterial diseases generally occur mostly during the summer and autumn rearing seasons. They are caused by bacteria parasitizing silkworms, multiplying in large numbers, and infecting the whole body through the blood circulation, mainly through wounds and food routes. The prevention and control measures are as follows: 1. Strict disinfection. Before, during, and after rearing, use bleaching powder solution containing 1% chlorine to strictly disinfect the rearing room, rearing tools, ancillary facilities, and surrounding areas. 2. Strengthen feeding management. When feeding mulberry leaves and handling silkworms, movements should be gentle and operations should be done carefully. Expand the rearing bed frequently,

2. Strengthen feeding management. When feeding mulberry leaves and handling silkworms, movements should be gentle and operations should be done carefully. Expand the rearing bed frequently. Silkworm density should not be too high, so as to reduce opportunities for wound infection.

3. Promptly remove diseased and dead silkworms. Collected diseased and dead silkworms should be burned in a centralized manner or buried deeply to reduce opportunities for infection in the rearing bed.

4. Supplement feeding with chloramphenicol. Chloramphenicol has an obvious preventive and therapeutic effect on silkworm bacteria. The preparation method is to spray 1 kg of aqueous chloramphenicol solution of 500-1000 units per milliliter onto 10 kg of mulberry leaves for supplemental feeding.

5. Store mulberry leaves properly. Storage time should not be too long, to avoid the mulberry leaves becoming heated and sticky, which allows bacteria to multiply in large numbers. Leaves should be picked and fed to silkworms fresh, reducing opportunities for food-borne infection.

6. Strengthen fertilization and cultivation management of mulberry trees and pest control work. Improve the quality of mulberry leaves, enhance the constitution of silkworms, and improve disease resistance.
