The mulberry silkworm, Bombyx mori L is a Lepidopteran insect, life cycle of which include: Egg, Larval Instars, Pupa within silky cocoon and adult moth. It is purely domesticated insect since long, which make it a quite delicate venture, easily susceptible to viral and other diseases. The viral diseases are difficult to manage due to a very short life cycle of silkworm. One of the most effective solutions is a timely detection of such infection so that to stop spread of the disease. The present attempt is concerned with studies on a polymerase chain reaction (PCR) with a set of specific primers to the Grasserie virus gene region was used to diagnose B. morinucleopolyhedro virus (BmNPV) infection which were made available from Eurofins Genomics India Pvt Ltd Bangalore. The nucleic acid DNA was extracted from the mid gut tissue of the fifth instar larvae of silkworms and was subjected for amplification. | Detection of grasserie virus BmNPV in the fifth instar larvae of silkworm Bombyx mori L Race PM x CSR2 through polymerase chain reaction
