Abstract
The application of the RNA interference (RNAi) mechanism promotes the development of novel approaches toward sustainable crop protection. Compared with traditional double-stranded (ds)RNA delivery systems, nanoparticles offer great advantages in delivering dsRNA to improve RNAi efficiency, thus promoting the development and practice of RNAi-based pest management strategies. Here, we described a transdermal dsRNA delivery system with a nanosized star polycation, and presented a method to improve RNAi efficiency to increase the control effect against aphids. Insect gene functional analysis and pest management can be achieved by this method.
