Nilaparvata lugens, the brown planthopper (BPH), is a serious pest species. BPHs cause significant damage to rice plants in Korea as well as other countries in East and Southeast Asia. As BPHs cannot survive winter in Korea, they annually migrate into Korea from foreign countries. The BPHs found in Korea are believed to originate from China, but most BPHs in China are also known to originate from Southeast Asia. To understand the origin of Korean BPHs, we conducted a genotyping‐by‐sequencing (GBS) study. We sampled BPHs from five locations in Korea and five countries in Southeast Asia and analyzed the GBS and sequencing results using various methods based on the f statistics and admixture graph analyses. We confirmed that the domestic BPHs shared a greater genetic drift than the BPHs from Southeast Asian populations over several years, implying that a continuous genetic substratum of Korea exists. This genetic substratum is genetically closer to BPHs from the southern part (Thailand and Cambodia) of Southeast Asia than to BPHs from the northern part (Bhutan, Myanmar and Laos) of Southeast Asia. In addition, direct gene flows from Southeast Asia seem possible, so Korea is considered a hotspot where diverse BPH populations mix. Therefore, the origin of Korean BPHs extends beyond China and as far as southern Southeast Asia. This result will help to understand and control the population dynamics of the Korean BPH population.
