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。
Planthoppers (brown planthopper, white-backed planthopper and brown planthopper) are the biological catastrophes that threaten our food security. Based on the high variability of planthopper infestation ability, high adaptability to pesticides, the spread of virus disease and long-distance ability to migrate, and the dynamic and virulence of planthopper migration and virulence in research Interspecies interactions and other mechanisms of catastrophic mechanism is not clear, proposed space-time dynamics of the planthopper migratory dynamics, virulence mutations, planthoppers spread virus disease, pesticides on planthoppers and their natural enemies of the ecotoxicological effects of rice Planthopper genomic data analysis and rice field planthopper population control function six research directions to clarify the inherent mechanism of planthopper catastrophe and provide a theoretical basis for the sustainable development of planthopper system.
