Qualitative Silk Cocoons in Silkworm, Bombyx Mori (L) Through the Topical Application of Acetone Macerative of Powder of Ganoderma Fruiting Body And Acetone Solution of It's Triterpenoid (Lucidone -D)

Terpene and terpenoid contents of ganoderma fruiting body is well esteemed fact. Terpenes and terpenoids are the significant Insect Juvenile Hormone Analogues (JHA). Ten mircolitres of acetone maceratives of (20 ppm) of powder of ganoderma fruiting body and acetone solution of triterpenoid (lucidone –d) compound were topically applied separately to the fifth instar larvae of bivoltine silkworm, Bombyx mori (L) [Race: (CSR6 x CSR26) x CSR2 x CSR27)] at 48 hours after the fourth moult. The cocoons spinned by the larvae were used for analysis of shell ratio and silk filament for the denier scale. The shell ratio of the cocoons harvested from untreated and acetone treated groups was found measured 20. 197 and 20.428 respectively. The denier scale of the silk filament obtained from the untreated control and acetone treated control groups was 2.726 and 2.738 respectively. Topical application of acetone maceratives of (20 ppm) of powder of ganoderma fruiting body and acetone solution of triterpenoid (lucidone –d) compound separately to the fifth instar larvae of bivoltine raced silkworm, Bombyx mori (L) [(CSR6 x CSR26) x CSR2 x CSR27)] was found resulted into the cocoons with 29.381 and 33.321 shell ratio respectively. The denier scale of silk filament reeled from the fruiting body group and triterpenoid (lucidone –d) groups was 2.825 and 3.222 respectively. The acetone maceratives of (20 ppm) of powder of ganoderma fruiting body and acetone solution of triterpenoid (lucidone –d) compound were found most significant with reference to the quality of the cocoons and silk filament in silkworm, Bombyx mori (L) [(CSR6 x CSR26) x CSR2 x CSR27)]. The powder of ganoderma fruiting body and acetone solution of triterpenoid (lucidone –d) compound deserve applicability and exert a significant influence.
