Abstract:

The topical application of acetone solution of Cucurbitacin-A at 48 hours after the fourth moult to the fifth instared larvae of silkworm, Bombyx mori (L) [Race: Double Hybrid - (CSR6 x CSR26) x CSR2 x CSR27)] was found significant influence on the parameteres of the silk cocoon and silk fibre. The weight of whole cocoon (deflossed), silk shell weight, weight of pupa and silk shell percentage or ratio in the group receipient of topical application of acetone solution of Cucurbitacin-A at 48 hours after the fourth moult was recorded 2.786** (±0.558); 0.917** (±0.057); 1.869 and 32.914*** respectively. The length of silk fibre (in meter); weight of silk fibre (in gram) and denier scale silk fibre obtained through reeling the cocoons harvested from the group of larvae receipient of topical application of acetone solution of Cucurbitacin-A at 48 hours after the fourth moult were recorded 1476.36* (±128.51); 0.793** (±0.114) and 4.834*** respectively.
