Abstract
Titanium dioxide(TiO 2 ) NPs have chemical properties such as high stability making,
highly a perfect choice for photo-catalysts, antimicrobial agents, and in preservatives. Plant
extracts may act both as reducing agents and stabilizing agents in the synthesis of nanoparticles.
TiO 2 NPs are widely used in silkworms for disease resistance. In this present study, Psoralea
corlyfolia-mediated TiO 2 nanoparticles significantly influenced the growth of silkworm larvae
and reduced the toxicity level of BmNPV infestation in treated larvae. The larval mortality was
less in theuntreated control (3.25 %) which is on par with Ankush (3.65 %) followed by TiO 2
NPs at 75 ppm (4.90 %). The treatment TiO 2 NPs 75 ppm recorded a cocoon weight of 2.23 g.
The lowest cocoon weight was recorded in 100 ppm of TiO 2 NPs (2.04 g).
