“…The small brown planthopper, Laodelphax striatellus Fallén (Homoptera: Delphacidae), is a widespread insect pest of rice ( Oryza sativa ) that causes rice stripe disease by transmitting Rice stripe virus (RSV) in East Asia . Heavy infestation has occurred in China, Japan and South Korea . Laodelphax striatellus ( L. striatellus ) and the viral disease that they transmit are difficult to control, especially in regions where the damage is mainly caused by immigrant populations .…”

“…The Philippines has been reported as a major source of the northward migration of brown planthoppers into temperate regions of China and Japan, based on trap catches, backwards telemetry and modelling (Otuka et al ., 2005, Otuka et al ., 2012). In our analysis the Philippine population of brown planthoppers formed a highly distinct cluster in the admixture analysis (Fig.…”

“…Weather simulations indicate that brown planthoppers could migrate from the Philippines into Taiwan and Japan, but also to southern China, sometimes in association with typhoons (Otuka et al ., 2005). The Philippines populations possibly mix with Indochinese populations in southern China before arriving in Japan (Otuka et al ., 2005, Otuka et al ., 2012), but this has not been tested further. Various features of the Philippine bugs suggest that they are different from the mainland populations.…”

Walter: https://orcid.org/0000-0003-1025-7101 26 Y Wang: https://orcid.org/Abstract 33 34 Brown planthoppers (Nilaparvata lugens) are the most serious insect pests of rice, one 35 of the world's most important staple crops. They reproduce year-round in the tropical parts of 36 their distribution, but cannot overwinter in the temperate areas where they occur, and invade 37 seasonally from elsewhere. Decades of research has not revealed their source unambiguously.38We therefore sequenced the genomes of brown planthopper populations from across 39 temperate and tropical parts of their distribution and show that the Indochinese peninsula is 40 the major source of migration into temperate China. The Philippines, once considered a key 41 source, is not significant, with little evidence for their migration into China. We find support 42 for immigration from the west of China contributing to these regional dynamics. The lack of 43 connectivity between the Philippines and mainland China explains the different evolution of 44 Imidacloprid resistance in these populations. This study highlights the promise of whole 45 genome sequence data to understand migration when gene flow is high -a situation that has 46 been difficult to resolve using traditional genetic markers. 47

“…RSV disease reemerged in the western provinces of Korea in -2008(Jonson et al 2009). Because of the close proximity of Korea and Japan to China, overseas migration of the insect vector from China led to outbreaks or a reemergence of RSV in Japan and Korea (Huang et al 2013;Jonson et al 2009;Otuka 2013;Otuka et al 2012;Qu et al 1997;Sakai et al 2011). However, no nationwide survey or analysis has been done on the RSV sequence variation among isolates in Korea.…”

Rice stripe virus (RSV) is a major rice-infecting virus in Korea that has caused a severe resurgence in the western provinces in 2007-2008. The outbreak of RSV in rice was caused by the small brown planthopper Laodelphax striatellus (an RSV vector), which overwinters in temperate climates. Mass immigration of its insect vector from China has been proposed as a critical risk factor in development of the disease. A nationwide survey was done in June and July 2012-2013 in 30 Korean provinces to confirm RSV sequence variation. The sequence of the nucleocapsid protein (NCP) gene and the intergenic region (IR) of RSV RNA3 was analyzed. A phylogenetic analysis of the NCP gene and the IR demonstrated that the 33 isolates were closely related to earlier reported isolates from Japan and China, but the secondary IR structure showed strong geographic clustering. This is the first report on a nationwide RSV survey of Korea. The results will provide information on the relationships among RSV isolates to understand the epidemiology of this rice disease and the effect of climate changes and insect migration.
