Abstract

In present investigation larvae of mulberry pyralid, Glyphodes pyloalis Walker (Pyralidae: Lepidoptera) which infest mulberry plantation were collected from different sericultural farms of Kashmir valley. The larvae were macerated and the homogenate obtained was subjected to microscopic examination which revealed viral infection. The virus was purified using percoll, differs distinctly in morphology from Bombyx mori Nuclear polyhedrosis virus (BmNPV) and was tentatively designated as (Gpv). The pathogenicity of the virus was also determined by inoculating (1 × 106/ml) of viruses to the zero day of 4th instar silkworms and the results were compared with that of Bm NPV. Peroral inoculation at a dosage of 1 × 106 viruses/ml caused no mortalities (larval/pupa) and all individuals survived, adults emerged successfully suggested it is avirulent to the silkworms. However, peroral inoculation of BmNPV at same dosage developed disease specific symptomlogy and caused 35 larval and 32 pupal mortalities and also decreased pupation drastically
