Development of a simplified RT-PCR without RNA isolation for rapid detection of RNA viruses in a single small brown planthopper ( Laodelphax striatellus Fallén)
2017
Background
The small brown planthopper (SBPH) is an important pest of cereal crops and acts as a transmission vector for multiple RNA viruses. Rapid diagnosis of virus in the vector is crucial for efficient forecast and control of viral disease. Reverse transcription polymerase chain reaction (RT-PCR) is a rapid, sensitive and reliable method for virus detection. The traditional RT-PCR contains a RNA isolation step and is widely used for virus detection in insect. However, using the traditional RT-PCR for detecting RNA virus in individual SBPHs becomes challenging because of the expensive reagents and laborious procedure associated with RNA isolation when processing a large number of samples.
