  • Abstract:
  • Eri-silkworm (Samia ricini), a nonmulberry silkworm species, is traditionally reared on castor (Ricinus communis) leaves, which provide optimal nutritional support for larval growth and cocoon development. However, the seasonal and regional unavailability of castor in many parts of Bihar, including Saran district, has prompted the need to explore alternative food plants. The present study investigates and compares the rearing performance of eri-silkworm on three host plants—Ricinus communis, Manihot esculenta (tapioca), and Heteropanax fragrans—under field conditions in the Saran district of Bihar. The larvae were observed for parameters such as larval duration, survival rate, cocoon weight, and silk yield. The results revealed that castor-fed larvae showed the highest growth rate, cocoon quality, and survival, while tapioca-fed larvae demonstrated comparable traits and adaptability. Heteropanax fragrans performed relatively lower in terms of larval development and cocoon characteristics. These findings support earlier research by Suryanarayana & Srivastava (2005) and Das et al. (2020), which emphasize the potential of tapioca and other locally available food plants as suitable alternatives for erisilkworm cultivation. This study encourages the use of region specific host plants to promote year-round rearing and enhance sericulture-based livelihoods in Bihar.
