KEYWORDS: BmIFV, diagnosis
In this study, a method for detection of an ssRNA viral pathogen that causes viral flacherie in the silkworm, Bombyx mori (L.) (Lepidoptera: Bombycidae), was used for the detection of B. mori infectious flacherie virus (BmIFV). A combination of nested and reverse transcriptase polymerase chain reaction was used for detection. Although BmIFV has been reported in almost all the sericultural regions of the world, there had been no reports of BmIFV incidence in India. Therefore, the confirmation of the presence of BmIFV in Karnataka, India, is of great significance. The present method is advantageous because it can be used to detect the virus by using samples from infected midgut tissues, thus simplifying and avoiding laborious genome isolation procedures. This method could help in early detection of BmIFV disease pathogens and help reduce crop losses.
