Flacherie is a serious disease of silkworms. What are the common
Clinical signs?
(Lime powder must be dusted on the rearing bed to reduce humidity!)
FLACHERIE IS a syndrome associated with bacterial diseases. Diseased/ dead silkworms, their faecal matter, contaminated mulberry leaves and rearing appliances act as sources of infection. Wide fluctuation in temperature and humidity with poor quality mulberry leaves are the major predisposing factors for flacherie.
Disease symptoms During the initial stages of infection the larva becomes lethargic and stops eating.
At an advanced stage infection the larva exhibits retarded growth, vomits gut juices and excretes semi solid faeces.
The larva becomes soft and translucent.
Finally the larvae ferments and the inner content turns into a black coloured liquid, which emits foul odour. Maintain hygienic condition in the silkworm rearing room by washing the rearing house and equipment with bleaching powder solution followed by disinfectants. Identify and pick out early stage infected larvae and destroy them. If previous crop is infected with flacherie, then care must be taken to disinfect rearing room appliances and surroundings before next rearing.
Proper rearing techniques have to be adopted by providing quality leaf according to stage of the worm. During monsoon season lime should be dusted on the rearing bed to reduce the bed humidity. Depending upon the stage of the worms, provide optimum temperature and relative humidity and avoid fluctuation of temperature and relative humidity.
