Until now, occurrence of rice stripe virus (RSV) is limitted in southern part of Korea. However, recently the occurrence of RSV is increased and spreaded in central part of Korea including Chungcheong and Kyonggi province. It is very difficult to distinguish RSV symptoms on virus symptom physiological damage of rice. We detected RSV viral RNA from infected rice and its insect vector Laodelphax striatellus using specific primer of RSV-polymerase and coat protein gene with reverse transcription (RT)-PCR. The result of RT-PCR, we observed specific band including RSV-polymerase (1,023 bp) and CP (969 bp) in both host of rice and insect vector.
Key Words: Laodelphax striatellus, RSV, RT-PCR
