From the studies made on the host and virus relationships among various strains of the silkworm, it has been demonstrated that the two cytoplasmic-polyhedrosis viruses, forming the tetragonal shaped and the hexagonal shaped polyhedra, are equal in virulence. On the other hand, the cytoplasmic-polyhedrosis virus seemed to be more infectious toward the silkworm than the nuclear-poly-hedrosis virus. General existence of a moderate but significant relationship between the interstrain susceptibilities to nuclear- and cytoplasmic-polyhedrosis viruses indicated that the mechanisms of the host to both the virus infections are similar to a greater extent.
