Abstract: The study reveals that Kerria lacca utilizes the host plant’s secondary metabolites, especially terpenoids to make the resinous encrustation surrounding itself, probably as a protective device. The rate of lac resin secretion largely depends on the plant terpenoids concentrations. The concentration of anthraquinone dyes present in the lac-encrustation is higher in Butea monosperma in comparison to Ziziphus mauritiana. The plant phenolics can also affect the rate of lac-resin production. It is also evident that K. lacca depends on the concentration of host plant phenolics to make its anthraquinone dye. K. lacca thriving on B. monosperma can produce greater amount of dye in which the concentration of phenolics is also higher in comparison to Z. mauritiana. The statistical analysis support the present studies also.
