[ Method ] Rice stem borers in western rice areas in Sichuan Province were composed of Chilo suppressalis, Tryporyza itwertulas and Sesamla inferens. C. sup- pressalis was the dominant population in most rice areas in western flee areas in Sichuan Province. T. incertulas had distribution and damage in Longquan, Qingbai- jiang and some rice areas, showing increasing trend of spread. The population of S. inferens was the minimum, but it caused serious damage in late period of rice. [ Conclusion] The result provided theoretical basis for proposing effective control measures against rice stem borers in western rice areas in Sichuan Province.展开更多
