Betatetravirus

Betatetravirus is a genus of viruses, in the family "Alphatetraviridae". Moths and butterflies serve as natural hosts. There are seven species in this genus. Infection outcome varies from unapparent to lethal.
Taxonomy.
The following species are assigned to the genus:
Structure.
Viruses in "Betatetravirus" are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear, around 6.5kb in length.
Life cycle.
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by ribosomal skipping. Moths and butterflies serve as the natural host. Transmission routes are oral.
