Diseases of Silkworm

Prevention and control of the disease

  1. No control measure for the disease has yet been evolved. The elimination of diseased eggs during grainage by microscopic examination and diseased larvae during rearing is the only preventive measures against the disease. Preventive measures can be taken in case of indoor operations of the cultural process, but in outdoor rearing of muga worm, the infection may come from extraneous sources.
  2. Follow the scientific inspection method of individual mother moth testing for detection of pebrine in egg production. Practice disinfection of grainage appliances before and after every grainage operation with 2% formalin.
  3. Ensure use of microscopically tested disease free disinfected eggs only.
  4. Practice surface sterilization of the eggs with 2% formalin for 5 minutes.
  5. Maintain hygienic conditions in egg production room and rearing sites.
  6. For basic stock maintenance, follow cellular method of rearing.
  7. Practice disinfection of rearing appliances before use.
  8. During rearing, test the faecal matters, unequal/ lethargic/ unsettled/ irregular moulters periodically. If pebrine spores are detected, reject the entire infected crop.
  9. Ensure the measures for destruction of diseased silkworm larvae/cocoons/moths/eggs.
