What is Thatte roga and how it is caused?
1. Thatte roga is a type of flacherie in silkworm 2. It is cause by streptococcus sp. And or Staphylococcs sp of bacteria in association with infectious flacherie virus 3. These pathogens are releases into the rearing tray/platform by diseases larvae along with feces and vomit 4. The released pathogens contaminate the rearing tray, platform and the mulberry leaf I the bed. They survive in the rearing tray/platform for long time and cause disease if they are not disinfected effectively. 5. They cause the disease in larvae that re reared in the contaminated tray. The rate of disease development depends on the temperature and humidity in that particular tray. 6. The bed temperature and humidity will be high in the tray in which there is accumulation of feces, wasted leaves and poor air circulation. Such conditions are suitable for the bacteria to multiply in the larvae and rearing bed. 7. In presence of virus in the larvae and high temperature condition, the disease development will be fa
