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.[1][2]
The following species are assigned to the genus, scientific name in parentheses:[2]
- Antheraea eucalypti virus (Betatetravirus antheraeae)
- Darna trima virus (Betatetravirus darnae)
- Dasychira pudibunda virus (Betatetravirus dasychirae)
- Nudaurelia capensis beta virus (Betatetravirus nudaureliae)
- Philosamia cynthia x ricini virus (Betatetravirus philosamiae)
- Pseudoplusia includens virus (Betatetravirus pseudoplusiae)
- Trichoplusia ni virus (Betatetravirus trichoplusiae)
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.[1]
