摘　　要：随着种植制度的变更和轻型栽培技术的推广,生产上大螟在局部地区已经由水稻次要害虫变成主要害虫,且有逐年加重趋势。但目前中国稻区多数仍沿用以二化螟为靶标的防治技术体系,亚致死剂量农药反而促进大螟种群增殖。为了加强大螟的防控研究和技术推广,笔者在整理中国大螟近几十年来与防治相关的文献报道基础上,针对大螟多寄主选择、倾向田边产卵等生物学特性、大螟发生与危害逐年加重和边际危害的特点,探讨了以性诱法为主导的预测预报方法,总结了农业防治以减低少虫源基数、生态调控以降低种群数量和科学测报精准施药等方面综合应用的防治技术研究进展,提出了未来研究中需重视大螟预测预报方法完善、大螟抗药性监测和转抗虫基因水稻的抗性风险评估。With the change of cropping system and the promotion of light cultivation technique, thepolyphagous pink stem borer Sesamia inferens has become the major rice pest in some areas. It is obvious thatthe heavy damage caused by S. inferens is increasing year by year. But the control technology system usingstriped rice borer as target is still applied in most rice areas at present, and sublethal dose of pesticides haspromoted population growth of S. inferens. In order to strengthen the research and technique promotion incontrol of S. inferens, considering the biological characteristics such as multi-host selection and spawning closeto the edge of the field, and the increasing occurrence and damage, prediction and forecasting method werediscussed based on the analysis of control-related literatures of S. inferens in recent decades. Study advancesin agricultural control methods, which were reducing insect source base, ecological regulation, scientificforecasting and precision spraying, were summarized. The future research was proposed to be concentrated onimproving forecasting methods, resistance monitoring and resistance risk assessment of transgenic rice.
