Due to outdoor rearing of tasar silkworm, the larvae are amenable to different abiotic and biotic stress conditions which lead to severe mortality of the larvae. Three different tasar silkworm rearing fields were selected for the present study. The a-biotic factors viz., Temperature, Relative humidity and rainfall were recorded regularly along with dead larvae due to different diseases and pests. The data collected were thoroughly analyzed. The results revealed that, fluctuation in the environment leads to increased disease incidence. The pest infestation was severe during the early instars of the silkworm. Existing field conditions along with fluctuating a-biotic factors play important role in the survivability of tasar silkworm larvae in outdoor condition.
