Abstract:  Invasive alien insects, as dangerous pests in newly introduced areas, present challenges such as delayed detection, difficult monitoring, rapid outbreaks and incomplete eradication. These issues have long been the emphases and difficulties in the field of biosecurity worldwide. In this article, we made an overview of the major progress in the studies on the mechanisms of population outbreak and causing disaster, monitoring and early warning technologies, and control measures for invasive alien insects in China. We also summarized and introduced the main contents of this special issue from three aspects: The researches on population dynamics monitoring, mechanisms of insect resistance, and green control technologies for pest insects. Finally, we prospected the development trends of standardization, informatization, intelligence, and greening of monitoring and control of invasive alien insects in the future, and proposed the key directions for future control and management strategies for these pests, in order to promote more efficient, integrated and sustainable control approaches through technological innovation.
