Abstract: China is the largest rice producing and consuming country in the world. The lack of abundance in rice production has a very important impact on China＇s food security. In recent years, small brown planthopper （SBPH） and viral diseases transmitted by SBPHs have caused serious damage to rice production in the rice-growing regions of the middle and lower reaches of the Yangtze River and North China. In this paper, research progress in the occurrence, damage, causes of outbreaks, control techniques and genetic studies of SBPH are reviewed and discussed, in order to assist further research on the prevention and control of Laodelphax striatellus （SBPH） and its transmitted viral diseases.
