| Abstract: | Abstract During August 1986 when there was a build up of Parasa lepida Cramer on coconut in the study area in Kerala, India, many dead larvae were found on the underside of the leaves. A few of these cadavers which were suspected to be infected by a virus were collected. Pathogenicity tests proved positive. PIBs were negative to stain by Giemsa, and section of the polyhedra shows that the virions are rod shaped. The pathogen is a multiple embedded baculovirus. |
