The long-term use of chemical insecticides to control stored-grain pests has caused problems like pest resistance and environment pollution. The article briefly introduces some common pests and the losses they caused. According to the requirements of green, environmental protection and safety of grain storage, the biological control technology for stored grain pests in the process of grain storage is discussed, and the research progress of the application of biological control technologies such as agents, pheromones, microbial source materials, plants and plant extracts were also introduced. We hope to develop ideas for the prevention of stored-grain pests, reduce or avoid the losses caused by the pests, provide reference for future research on stored-grain pests control technology.
