| Abstract | ||
| Quality of mulberry varieties is affected the cocoon production. Selection of the best variety for rearing is primary key for successful rearing. Five mulberry varieties were investigated intend Morus alba Linn. Var. Kokuso-27(M1), Morus alba Linn. Var. Kaeryang- Bbong (M2), Morus alba Linn. Var. Canava-2 (M3), Morus alba Linn. Var. Ardnyl (M4) and Morus alba Linn. Var. Suisfen (M5). Characters of larval weight during third, fourth and fifth instars, growth rate, consumed food, approximate weight of food digested (AD), approximate digestibility (AD%), efficiency of conversion of ingested food to body substance (ECI), efficiency of conversion of food digested to body matter (ECD) of fourth and fifth instars, consumed food and fresh cocoon yield per 1000 larvae and leaf /cocoon ratio were investigated for all varieties under study. The results revealed that M1 and M5 have better mean values for larval weight during third, fourth and fifth instars, growth rate, consumed food, efficiency of conversion of ingested food to body substance (ECI) and efficiency of conversion of food digested to body matter (ECD) of fourth and fifth instars. As well as, varieties of M1 and M5 were best for approximate weight of food digested (AD), approximate digestibility (AD%) for fourth and fifth instars, leaf/cocoon ratio because of it earned the lowest average. | ||
