EVALUATION OF OCIMUM SANCTUM LEAF EXTRACT PERFORMANCE ON COCOON PRODUCTION AND SILK QUALITY IN BOMBYX MORI L

The sericulture is an ancient traditional industry more Asia people is depended on it.The silkworm (Bombyx mori L) is a well-known beneficial lepidopteran insect cultivated for the production of fine and lustrous silk fibre, often referred to as the Queen of Textiles.Tulsi is an aromatic medicinal plant its contain diverse phytochemicals such as oleanolic acid, ursolic acid, etc., they exert significant biological effects on various animal systems.In this study, we investigated the effect of o.sanctum extract in variant type of concentration (1.0 % ,2.0%, 3.0%) on the growth 5th stage silkworm larvae on the biological and commercial traits of Bombyx mori L. the silkworm fed fresh mulberry leaves with sprayOcimum sanctum extract of coating leaves surface area and supplemented 4th and 5th instar silk worm.That study results fifth instar silkworm larva(Length and weight,Weight of cocoonand pupae) and silk parameters(shell ratio, Length of silk filament,denier)highly effect in larval. And thus, increase silk qualityas compared to the control. the commercial parameters different concentration made different types of value get but economical parameters increase significantly. And some concentrations gave parameters result maximum valueas compared to the control group.it is ratifyOcimum sanctum plant extract spray a coated mulberry leaf fed silk worm larval commercial traits positive effect Bombyx moriL.
