中文摘要：
稻飞虱是中国和许多国家水稻生产上的主要害虫，属r对策暴发危害类型。其中，褐飞虱和白背飞虱是典型的远距离迁飞性害虫，具有大区域同期“突增”和“突减”的灾变特性；灰飞虱则主要以本地越冬为主，远距离迁飞对种群结构的影响较小，但其传播的病毒病对水稻生产的影响更甚。针对3种稻飞虱的生物学特性，本文发展了稻飞虱田间种群发生与危害等的调查与取样技术，为其种群发生及其监测预警提供技术支撑。
英文摘要： Rice planthoppers, including the brown planthopper (BPH), Nilaparvata lugens, white-backed planthopper (WBPH), Sogatella furcifera and the small brown planthopper (SBPH), Laodelphax striatellus are key insect pests in the paddy-fields of Chinaand many other countries. These species are r-strategists and tend to have periodic outbreaks. All three species are typically long-distance migrants and often simultaneously occur over a large geographic scale during outbreaks. The SBPH mainly overwinters locally and its long-distance migration has little impact on its population structure. However, its transmission of viruses to rice plants is more serious. Based on the biological characteristics of N. lugens, S. furcifera and L. striatellus, we developed methods and technologies for the surveying and sampling of these species that can improve the population monitoring and the forecasting of population outbreaks.
