摘　　要：S-烯虫酯是一种绿色、高效且对环境及非靶标生物安全的生物化学农药。然而,由于其在有氧、光照等条件下不稳定及不溶于水等问题,限制了其实际应用。本研究以玉米醇溶蛋白为载体,使用反溶剂法制备了负载S-烯虫酯的水分散体,实现了S-烯虫酯的高效负载。探讨了不同浓度的玉米醇溶蛋白和S-烯虫酯对纳米水分散体的微观形貌、载药量、包埋率、释放特性、贮藏稳定性及对烟草甲的防治功效的影响。S-methoprene is a green,efficient,and environmentally friendly biopesticide that is safe for non-target organisms.However,due to its instability under aerobic and illuminated conditions and its low solubility in water,its application has been challenging.In this study,zein(a corn protein)was utilized as a carrier,and a nanoparticle delivery system was prepared using the antisolvent method,achieving efficient loading of S-methoprene.The influences of different concentrations of zein and S-methoprene on the morphology,drug-loading capacity,encapsulation efficien-cy,release properties and storage stability of the composite nanoparticles were investigated.
