Abstract：Agricultural nanotechnology has developed rapidly in recent years, promoting the gradual development of traditional agriculture as an interdisciplinary field. Nanocarriers have four functions and applications. The first is to deliver dsRNA to penetrate the body wall, thereby regulating the development and growth of pests. The second is to deliver viral DNA to kill non-host pests, thereby broadening the host-range of viruses. The third is to deliver Bt toxin to kill non-sensitive pests, which provides new possibilities for the management of pesticide resistance. The fourth is to deliver pesticides, which can increase the rate of pesticide use while at the same time, decreasing the amount of pesticides applied and broadening the range of pests under control. Based on recent researches, this paper reviews progress on the research and application of nanotechnology in green pest control, and discusses future prospects for research on, and utilization of, this technology.
