Tasar silkworm is a subtropical, polyphagus and sercigenous insect generally known for their valuable product known as silk. The insect is wild in nature and cannot be domesticated completely. Therefore the insect is directly exposed to the external environment and under the continuous threat of microbial infections. The different life stages of the silk insect are infected by no of pathogens including bacteria. The bacterial diseases cause significant loss in cocoon crop and thus hamper the silk economy. In the present study the local Daba TV ecorace were used for the isolation of bacterial pathogens and their subsequent study to identify them along with their potential to impart death in 4th and 5th larval instars. A total of seven bacterial isolates were purified from Anal Lip (AL) and Rectal Protution (RP) showing infected instars. Upon identification, five different bacterial genus were verified using online verification tool, Microrao. The severity of the different bacterial isolates was found different, Salmonella spp. & Shigella spp. with % Death average (45.0) and (40.0)were identified as most severe, while E. coli cause moderate(30.0) and Enterobacter and Enterococcus were found to have least pathogenicity (20.0) for 4th and 5th larval instars.
