A wide range of formulations based on Bacillus thuringiensis (Bt) has been developed to control lepidopteranpests in agriculture and forestry. By using the Pickering emulsion technique, Bt was encapsulated to improveits activity and stability under UV-A exposure. In order to assess the effectiveness of this formulation inpreventing deactivation by UV-A radiation, spore viability and mortality in Ephestia kuehniella (E. kuehniella)Zeller larvae were measured under UV-A radiation. Based on both tests, emulsion formulation with ۰.۰۱ g ofGO in emulsion has the highest viability protection. As a result, Pickering emulsion formulations stabilized byGO successfully protect Bt against UV radiation
