Mark record


The spruce budworm, Choristoneura fumiferana (Clemens)m, is susceptible to two types of granulosis virus. One is characterized by the formation of mostly small ellipsoidal inclusion bodies, the second by the formation of large cubic, inclusion bodies. Different shapes and sizes of inclusion bodies were formed when these viruses multiplied in the same tissues, some resembling the ellipsoids, others the cubes.
