Abstract: 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.
