我国水稻螟虫发生及治理研究进展

Research advances on the occurrence,damage and management of rice stem borers in China

水稻螟虫是我国水稻生产过程中的重要害虫种类之一,其为害范围广,所造成的经济损失巨大,且在我国主要稻区呈现逐年加重的发生趋势。本文重点以二化螟为例,概述了近年来水稻螟虫发生与为害现状、抗药性演化、抗螟水稻种质资源挖掘与品种创制、水稻螟虫生理生化与毒理学研究及新型杀螟药剂研发、水稻螟虫寄生蜂资源及其利用、水稻螟虫生态调控技术等方面的主要研究成果,以期为深入了解我国水稻螟虫发生为害及其治理研究现状提供依据,并为水稻螟虫的可持续控制与水稻绿色生产的实践提供帮助。

Rice stem borers are one of the key pest species in rice production in China,causing a wide range of harm and huge economic losses.Its occurrence in major rice areas in China is continuously and seriously increasing.This article focuses particularly on the rice stripped stem borer,Chilo suppressalis(Walker),and provides a review of the main research achievements in recent years.The review covers various aspects for rice stem borers,including the occurrence and damage status,the evolution of insecticidal resistance,the exploration of germplasm resources and the creation of rice resistance varieties,the physiological,biochemical and toxicological researches of rice stem borers,the development of new types of insecticides,the utilization of parasitic wasp resources and the ecological management approaches.This review provides a foundation for an in-depth understanding of the damage,occurrence and management of rice stem borers in China,and offers assistance for implementing sustainable rice stem borers control practices and promoting the green and health production of rice.
