Abstract: Mulberry, Morus Alba, (L.)Leaves are the predominant food source for silkworm, Bombyx mori rearing.Pink mealy bug infests the mulberry plants and cause Tukra diseases that leads to qualitative loss of mulberry plantation.Hence a preliminary study was carried out using plant extracts as natural botanicals origin by spraying tukra infested mulberry leaves.The botanical extract sprayed to tukra infested mulberry leaves fed to the silkworms and its impact on Trehalose, Phosphorylase activity in tissues like fat bodies and haemolymph was studied.For the study, good healthy leaves(Control)and plant extracts viz., Azadirachta indica,Ocimum Sanctum,&parthenium hysterophorus were sprayed to tukra infested V1 mulberry variety and fed to Silkworm (CSR2 Bivoltine hybrid).The trehalose activity gradually increased, this increase however was significant (P>0.05).The elevation in total phosphorylase activity gradually progressed from day 3 to day 6, in the order: day 3<4<5<6; and the magnitude of increase between one day to the other were statistically significant when fed with natural extracts sprayed mulberry to silkworm Foliar spray of the extracts hold greater promise for control of tukra infested mulberry leaves and did not affect enzyme activity in silkworms.This can sturdily suggest that the aqueous Extract sprayed infested mulberry leaves can be effectively utilized for the silkworm rearing instead of pesticides insecticides for mulberry sericulturistes.
