(Lepidoptera: Saturniidae) Fed with Different Castor (Ricinus communis
L.) Genotypes]]>ShifaKedir Emana Getu SoriWaktole 12014111Growth, development, reproduction and yield of silkworms depend on the availability
and supply of preferred host plants having good agronomic and nutritional characteristics.
Eri-silkworm, Samia cynthia recini B. is a multivoltine and polyphgous
insect feeding on diversified host plants among which castor is a primary host
plant. There is differential preference for the different varieties of castor
by S.c. ricini. In the present study, eight different castor genotypes;
namely Abaro, Acc 106584, Acc 203241, Acc 208624, Ar sel, Bako, GK sel and local
were evaluated for their merits as feed and nutritional sources for white plain
S.c. ricini at Melkassa Agricultural Research Center, Ethiopia. The treatments
were arranged in a Completely Randomized Design (CRD) in three replications.
Fifty worms were used in each replication. Significant difference was observed
in rearing performance of eri-silkworms when fed to leaves of different castor
genotypes. Among castor genotypes fed to eri-silkworm, Abaro fed worms showed
medium to maximum records of matured larval weight (8.17 g), effective rate
of rearing (74.68%), survival rate (76.08%), cocoon weight (3.34 g), pupal weight
(2.86 g), shell weight (0.48 g), silk ratio (14.49%), fecundity (382.00), hatchability
(88.17%) and shorter larval duration (584.17 h). In conclusion, genotype Abaro
was superior to the other genotypes in improving the rearing performance of
eri-silkworms and can be recommended for further research and development work
in integrating silkworm activities for silk and oil seed productions.]]>Bhattacharya, A., B.B. Bindroo and R. Chakravorty,20062006Belli, C., 1947101317Bindroo, B.B., N.T. Singh, A.K. Sahu and R.
