Southern rice black-streaked dwarf virus (SRBSDV) is a plant pathogenic virus of the family Sedoreoviridae, causing diseases in rice and maize, resulting in significant crop losses in Southern Asian countries. It is a member of the genus Fijivirus. It is not to be confused with the Rice black-streaked dwarf virus, as this virus does not contain the same insect vectors, and is an entirely separate virus. The sole transmitter of SRBSDV is Sogatella furcifera, aka the "white-backed planthopper" (WBPH). Close relative to the Laodelphax striatellus (small brown planthopper), which transmits the RBSD virus.

Transmission
editThe SRBSDV spreads via the WBPH, the sole transmitter of this virus.[1] The insect picks up the virus when feeding on an infected plant, proceeding to spread it to other plants.[2]
Affected areas
editSRBSDV was first found in southern China in 2001.[3] Since then, it has spread to other parts of East Asia, causing serious damage to rice and maize crops in countries like China, Vietnam, and Japan.[4]
Most affected countries have already implemented preventative actions, such as nets to protect crops, treating seeds with chemicals, and spraying seedlings with pesticides.[1] Scientists are also trying to create rice and maize plants that are naturally resistant to the virus.[1]
