| 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... |
