The silk produced by <em>Philosama ricini</em> is called Eri silk. Eri silk is known as Non Violence silk or Piece silk. It is also said to be Poor Person’s silk. The Eri silkworm <em>(Philosamia ricini</em>) is multivoltine, holometabolus, non-mulberry, completely domesticated and feed on castor (<em>Ricinus communis</em>) leaves.We observed the effect of different seasons on rearing performance of Eri silkworm in respect of different larval parameters (larval weight, larval length, ERR% and pupation) and cocoon parameter (cocoon weight, pupae weight, shell weight &amp; shell %). Our findings clearly indicated that the rearing performance of Eri silkworm was better in spring season than winter and autumn season of Ujjain district M.P.</p> ER -
