中文摘要： 稻飞虱（褐飞虱、白背飞虱和褐飞虱）是威胁我国粮食安全最大的生物灾害。本文基于稻飞虱致害能力的高度变异性、对农药的高适应性、传播病毒病和具有远距离迁飞能力等特点，以及研究中存在的稻飞虱迁飞动态、致害性变异和种间互作关系等灾变机理机制不清楚，提出了稻飞虱迁飞时空动态、致害性变异、稻飞虱传播的病毒病、农药对稻飞虱及其天敌的生态毒理效应、稻飞虱基因组数据分析和稻田生态系统对稻飞虱种群数量调控功能6个研究发展方向以阐明稻飞虱灾变的内在机理，为稻飞虱可持续治理体系建设提供理论依据。
英文摘要： Rice planthoopers have been the most destructive pests for food security and the chemical pesticides used to control them are affecting ecological and food safety in China. Therefore, integrated approach for intensive rice production and sustainable control of rice planthoppers has been becoming of the most important task. The molecular mechanism for the pests adapting intensive rice ecosystem and ecological bases for integrating technology for intensive agriculture and sustainable pest management would be studied to improve understanding. 6 subprojects, including migration and temporalspecial dynamics of rice planthopper populations; genetic bases of rice resistance to planthoppers and planthopper virulence; ecological and molecular mechanism of epidemic of rice virus diseases transmitted by planthoppers; ecological toxicology of pesticides on planthoppers and their natural enemy; data analysis for planthopper genome and techniques for identifying functional genes and regulating function and relevant mechanism of rice ecosystem on planthopper population development, will be further explored to provide theoretical and technical bases for establishing outbreak monitoring and warning systems for rice planthoppers and virus diseases, development of resistant varieties and program for sustainable management of these pests.
