An encapsulated formulation of Bacillus thuringiensis (Bt) was produced by the Pickering emulsion technique to improve its activity and stability under UV-A radiation. In this technique latex particles, GO nanosheets, olive oil, ethanol, and water were used to encapsulate Bt in colloidosomes. The protective efficacy of this formulation in protecting Bt subsp. Kurstaki against deactivation by UV-A irradiation was measured, so that spore viability and mortality on Ephestia kuehniella (E. kuehniella) Zeller larvae under UV-A radiation are investigated. According to the results of both tests, encapsulated formulation at a concentration of 0.045% has the highest protection of viability. Hence, colloidosome microcapsule formulations successfully provide good protection against UV radiation.

通过Pickering乳液技术制备了苏云金芽孢杆菌（Bt）的胶囊化制剂，以提高其在UV-A辐射下的活性和稳定性。在该技术中，乳胶颗粒，GO纳米片，橄榄油，乙醇和水被用于将Bt包封在胶体中。该制剂在保护Bt亚种中的保护功效。测量了Kurstaki抵抗UV-A辐射的失活，从而使孢子活力和死于Ekustia kuehniella（E. kuehniella）Zeller上研究了UV-A辐射下的幼虫。根据两个测试的结果，浓度为0.045％的封装制剂具有最高的生存能力保护。因此，胶体微胶囊制剂成功地提供了针对紫外线辐射的良好保护。
