| 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... |

| Comparison of eri silkworm rearing by using different major food plants, different lines of kesseru(Heteropanaxfragrans); Thai and Indian lines, and cassava Rayong 72 was conducted. The results showed that eri silkworm fed with kesseru leaves and cassava leaves has similar life cycles, 57-73 days and 53-73 days, respectively. Using Indian kesseru, larval (1-5 instar) and adult survival rates were 100%. Cocoon yield obtained from feeding with Rayong 72 was significantly higher (P<0.05) than feeding with both 2 lines of kesseru. However, average yields of fresh cocoon, pupa weight, %cocoon shell, total shell weight and fresh cocoon weight/10,000 larvae derived from cassava feeding were 2.2312 g, 1.9029 g, 14.37%, 9.52 g, and 22.31 kg, respectively, and... |
