Research progress on Sesamia inferens (Lepidoptera: Noctuidae): a systematic review

The pink stem borer, Sesamia inferens, is an important pest on a variety of gramineous crops, including rice, maize, sorghum. In recent years, it has been expanding northward to infest wheat crop and has posed a potential threat to China's food security. This study has noted a significant increase in research on S. inferens since 2010, with substantial improvements in both the quantity and quality of published studies. However, there is a lack of systematic reviews synthesizing existing knowledge on this pest currently. To advance our understanding of research progress and provide foundational insights for future investigations, this study systematically reviewed the research progress of S. inferens in terms of distribution and damage, bioecological characteristics, integrated control strategies, artificial rearing techniques and molecular biology. This study also summarized and analyzed the current research status of S. inferens, and further proposed recommendations from two perspectives: pest control and fundamental research. Regarding control measures, it is suggested to strengthen resistance management for transgenic crops, enhance resistance governance of mainstream inseticides, and improve the development and application of trap crops. In terms of fundamental research, priorities should include advancing basic studies on resistance breeding, exploring and utilizing natural enemy insect resources, and investigating the mechanisms underlying biological phenomena.
