Control of bacterial Diseases in Silkworm, Bombyx mori

Bombyx mori bacterial disease usually occurs in summer and autumn. It is caused by a large number of bacterial parasitic silkworms and infects the whole body with blood circulation. It is mainly caused by trauma and food transmission to the whole body. The prevention and treatment measures are as follows:

1. Before, during and after sericulture, a bleach solution containing 1% chlorine should be used to strictly disinfect silkworm furniture, ancillary facilities and surrounding places.

Second, strengthen feeding and management, when feeding mulberry and silkworm, the action should be light and carefully operated. Bombyx mori should be expanded frequently, and the silkworm head should not be too dense, so as to reduce the chance of infection caused by silkworm trauma.

Third, timely elimination of sick and dead silkworms, picking up dead silkworms should be burned or buried deeply, so as to reduce the chance of silkworm infection.

Fourth, chloramphenicol has obvious preventive and therapeutic effect on silkworm bacteria. The blending method is to add food by spraying 10 kilograms of mulberry leaves with 1 kilogram of chloramphenicol aqueous solution per milliliter.

Fifth, reasonable mulberry storage time should not be too long to avoid mulberry leaves being hot and sticky and bacteria multiply in large numbers. It is necessary to pick leaves and feed silkworms now so as to reduce the chance of food transmission.

Sixth, strengthen mulberry fertilizer management and pest control work to improve the quality of mulberry leaves, enhance the physique of silkworms, and improve the ability of disease resistance.
