摘要
Shellac was evaluated as radiation protection for the bacterium Bacillus thuringiensis var. entomocidus against Spodoptera littoralis larvae. Shellac provided excellent protection to B, thuringiensis. The efficacy of shellac in the protection of entomocidal activity of B. huringiensis var. entomocidus against UV irradiation has been studied. Results obtained by the absorbtion and the bioassay of residual entomocidal activity of B, thuringiensis var. entomocidus after exposure to UV irradiation showed that shellac is an excellent photpoprotective agent.
