本文综述了近年来对灰飞虱、白背飞虱和褐飞虱在东亚的迁飞研究。灰飞虱（Laodelphax striatellus）最近在中国东部江苏省爆发。该省的人口密度在2000年代初开始增加，并在2004年达到顶峰。2005年，水稻条纹病毒（Rice stripe virus，RSV）在L.纹状体最高为31.3%。此后，水稻条纹叶枯病在全省范围内严重蔓延。由于RSV媒介的迁移，水稻条纹叶枯病传播到邻国日本和韩国。L.分析了2008年发生的一种条纹虫，当时一种缓慢移动的冷涡，一种低压系统，从江苏到达日本西部，将昆虫带入日本。随后，水稻条纹叶枯病在日本这些地区严重流行。在韩国，类似的情况在2009年、2011年和2012年也发生过。通过后向轨迹分析，估计他们的移民来源地也在江苏。水稻黑条矮缩病毒（Rice black streaked dwarf virus）是以L. striatellus最近在中国东部重新出现，并且已经给出了该病毒海外迁移的证据，就像RSV的迁移一样。提出了一种预测白纹伊蚊海外迁飞的方法。日本、中国和韩国的研究机构已经开发了striatellus。对预测结果的评估表明，该方法正确预测了2008年至2011年东亚发生的移民事件。南方水稻黑条矮缩病毒（Southern rice black-streaked dwarf virus，SRBSDV）在广东省首次发现。它的矢量是S。furcifera。2009年，中国南部爆发了SRBSDV，同年蔓延到越南。2010年在日本也发现了这种疾病和病毒。疫情引发了许多移民研究，以调查中国具体的春夏移民路线，并提出了增加广东和广西早期抵达的移民来源。褐飞虱也是水稻的重要害虫。讨论了它在中南半岛半岛的迁移情况和在中国的返回情况。
This review examines recent studies of the migration of three rice planthoppers, Laodelphax striatellus, Sogatella furcifera, and Nilaparvata lugens, in East Asia. Laodelphax striatellus has recently broken out in Jiangsu province, eastern China. The population density in the province started to increase in the early 2000s and peaked in 2004. In 2005, Rice stripe virus (RSV) viruliferous rate of L. striatellus peaked at 31.3%. Since then, rice stripe disease spread severely across the whole province. Due to the migration of the RSV vectors, the rice stripe disease spread to neighboring countries Japan and Korea. An overseas migration of L. striatellus that occurred in 2008 was analyzed, when a slow-moving cold vortex, a type of low pressure system, reached western Japan from Jiangsu, carrying the insects into Japan. Subsequently the rice stripe diseases struck these areas in Japan severely. In Korea, similar situations occurred in 2009, 2011, and 2012. Their migration sources were also estimated to be in Jiangsu by backward trajectory analysis. Rice black-streaked dwarf virus, whose vector is L. striatellus, has recently re-emerged in eastern China, and the evidence for overseas migrations of the virus, just like the RSV’s migrations, has been given. A method of predicting the overseas migration of L. striatellus has been developed by Japanese, Chinese, and Korean institutes. An evaluation of the prediction showed that this method properly predicted migration events that occurred in East Asia from 2008 to 2011. Southern rice black-streaked dwarf virus (SRBSDV) was first found in Guangdong province. Its vector is S. furcifera. An outbreak of SRBSDV occurred in southern China in 2009 and spread to Vietnam the same year. This disease and virus were also found in Japan in 2010. The epidemic triggered many migration studies to investigate concrete spring-summer migration routes in China, and the addition of migration sources for early arrivals in Guangdong and Guangxi have been proposed. Nilaparvata lugens is also an important insect pest of rice. Its migration situations on the Indochina peninsula and return migrations in China are discussed.
