| Eri silkworm (Samia ricini D.) is an important wild silkmoth of world textile industry, this study experiments on the increasing yield of eri silkworm using 3 commercial lines of castor (Ricinus communis) TCO101, 207 and 208 in comparison with indigenous castor line (InL) and CaKKU1 line. The eri silkworm fed with each line had similar period of life cycle lasting 52-72 days. Survival percentage of eri silkworm when fed with castor TCO101 and CaKKU1 was the highest with 93.33% (larva-adult) and statistically different (P<0.05) to others. Using TCO101, the eri silkworm yields such as 5th instar larval weight, fresh cocoon weight, pupa weight, shell weight,percent of cocoon shell, total shell weight, fresh cocoon weight/10,000 larvae were 8.2530 g, 3.3799... |
