A group of entomopathogenic viruses that infect arthropods. According to the International Committee on Taxonomy of Viruses (ICTV), CPVs are classified under the family Reoviridae and genus Cypovirus. Cytoplasmic polyhedrosis viruses have a very wide host range, affecting mainly lepidopterous insects. Cytoplasmic polyhedrosis has been recognized as one of the most important diseases of the silkworm, inflicting substantial economic losses to the sericulture industry in Japan.

The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host.
Industry:Agriculture
A group of pathogens comprising the smallest known agents of infectious disease. They are unencapsulated and are capable of replicating autonomously in susceptible cells. Positively identified viroids composed of single-stranded RNA have been isolated from higher plants, but the existence of DNA viroids pathogenic to animals is suspected.
