This study has been undertaken to study the yield gap in the farm and farmers level of Philosamia ricini or eri silkworm. Evaluations were conducted in field and the performances were analyzed. The yield traits such as cocoon weight, shell weight, Pupal weight, Silk ratio and Effective Rate of Rearing percentage and the developmental traits such as incubation period, fecundity, hatching period, hatching percentage, larval weight, larval duration, larval survivability was calculated for comparison with values of the ecoraces . The sample size taken was 50 (larvae / cocoons) selected randomly. This study help to quantify the yield parameters of Eri silkworm and find out the major cause for yield gap to make the sector sustainable and economically vibrant among poor villagers of Jagatsinghpur district of Odisha.
