The LAMP-LFD for detecting BmNPV was developed by amplification at 61 °C for 45 min.
Sensitivity of LAMP-LFD was 100 times higher in comparison to PCR.
The LAMP-LFD was specific for BmNPV.
We applied the LAMP-LFD to detect BmNPV in the hemolymph and feces.
The LAMP-LFD is a simple, rapid and reliable method for detection of BmNPV.
