Abstract
The discovery that cytoplasmic polyhedrosis viruses (CPVs) contain a tensegmented double-stranded RNA (dsRNA) genome confirmed that they have many biochemical characteristics in common with members of the Reoviridae (Kalmakoff et al., 1969; Fujii-Kawata et al., 1970). They are most clearly distinguished from other members of this family in having virus particles that lack a double capsid layer and that are commonly occluded within large proteinaceous inclusion bodies ("polyhedra") during replication (Matthews, 1979). In addition, their host range appears to be restricted to arthropods, and there is only one report of a CPV infection outside the Insecta (Federici and Hazard, 1975). The limited studies that have been carried out also suggest that they are genetically distinct from other genera within the Reoviridae (Black and Knight, 1970; Martinson and Lewandowski, 1974; Kodama and Suzuki, 1973). For these reasons, they have been classified as a distinct genus, but no precise generic name has yet been allocated (Matthews, 1979).

It seems that the transcription of every segment starts at the same time, although the transcribed RNA for the shorter segment group is released from a virion faster than the larger group.

28 Citations1982Robert E. Smith, Yasuhiro Furuichi
Two structurally different classes of oligonucleotides accumulate in vitro in cytoplasmic polyhedrosis virus (CPV) transcription mixtures in molar excess as compared to the completed RNA products, implying that these unusual compounds may be produced reiteratively during initiation when RNA chain elongation and capping are uncoupled.
Journal of Molecular Biology5′-terminal structure of messenger RNA transcribed by the RNA polymerase of silkworm cytoplasmic polyhedrosis virus containing double-stranded RNA
27 Citations1974Kunitada Shimotohno, Kin‐ichiro Miura
The RNA polymerase in silkworm cytoplasmic polyhedrosis virus particle transcribed the nucleotide sequence of one chain of the double-stranded RNA genome, which consists of ten segments, and one chain carrying uracil at the 3′-terminus is selected as a template and is transcribed from the terminal nucleotide.

Journal of Invertebrate PathologyA cytoplasmic-polyhedrosis virus, Smithiavirus pectinophorae sp. n. of the pink bollworm, pectinophora gossypiella (Saunders)
27 Citations1966C. M. Ignoffo, Jean R. Adams
A new species of cytoplasmic-polyhedrosis virus is described from the pink bollworm, Pectinophora gossypiella, which feeding larvae on virus-treated diets significantly reduced pupal weight, pupation rate, adult emergence, and may possibly reduce adult longevity, fecundity, and egg viability.
Journal of Invertebrate PathologyPersistence of insect viruses in field populations of alfalfa insects
27 Citations1974Y. Tanada, Esther M. Omi
The persistence of viruses of five insects was observed in alfalfa fields, and the GVs and CPVs isolated from these insects were transmitted to nearly all of the other four species, but the NPVs appeared to be host specific.

Journal of Invertebrate PathologyRegeneration of midgut epithelial cell in the silkworm, Bombyx mori, infected with viruses
24 Citations1978Hajime Inoue, Masamichi Miyagawa
In the larvae of the silkworm, Bombyx mori, the regeneration of midgut cells infected with a cytoplasmic polyhedrosis virus, a flacherie virus, and a small DNA virus was studied.

23 Citations1969F. T. Bird
Cytoplasmic polyhedrosis viruses are, in general, more infectious to spruce budworm, Choristoneura fumiferana (Clemens), and forest tent caterpillar, Malacosoma disstria (Hübner), than the nuclear polyhedritis viruses which affect these insects.
