英文摘要	In recent years, starch microparticles have gained interest in many fields. However, low production, uncontrollable size, and varying size distribution hinder their practical application. Here, we adopt a premix membrane emulsification (PME) method to prepare starch microcapsules at high production rates. The process conditions were optimized to fabricate uniform microcapsules with controllable sizes and narrow size distribution (PDI < 0.1). Through encapsulating avermectin (Av), a kind of water-insoluble pesticide, into the shell of the microcapsules in situ during the process, we developed a pesticide delivery system that enabled a controlled and consistent release of Av over a period of 2 weeks. Kinetic analysis indicated that the mechanisms of Av release involved non-Fickian and Case-II transport. The diameters (0.70-4.8 mu m) of the microcapsules and Av contents (16-47%) were adjusted to achieve suitable release profiles. The results will lay the foundation for further field experiments.
