Genera

Nudiviridae is a family of viruses, the nudiviruses. Insects and marine crustaceans serve as natural hosts. There are currently three species in this family, divided among 2 genera. Diseases associated with this family include: death in larvae, chronic disease in adults.[1][2]

Taxonomy[edit]

Group: dsDNA

[2]

Structure[edit]

Viruses in Nudiviridae are enveloped, with rod-shaped geometries. Genomes are circular.[1]

Genus Structure Symmetry Capsid Genomic arrangement Genomic segmentation
Alphanudivirus Rod-shaped Enveloped Circular
Betanudivirus Rod-shaped Enveloped Circular

Life cycle[edit]

Viral replication is nuclear. DNA-templated transcription is the method of transcription. The virus exits the host cell by nuclear envelope breakdown, and nuclear pore export. Insects and marine crustaceans serve as the natural host. Transmission routes are parental and sexual.[1]

Genus Host details Tissue tropism Entry details Release details Replication site Assembly site Transmission
Alphanudivirus Insects:Beetles, Crickets Larva:midgut epithelial cells, then systemic spreading. Adult: midgut epithelial cells Pinocytosis Budding Nucleus Cytoplasm Feeding and/or Mating
Betanudivirus Lepidopterans None Pinocytosis Budding Nucleus Cytoplasm Unknown
