Omegatetravirus is a genus of viruses, in the family Alphatetraviridae. Moths and butterflies serve as natural hosts. There are three 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]
- Dendrolimus punctatus virus (Omegatetravirus dendrolimi)
- Helicoverpa armigera stunt virus (Omegatetravirus helicoverpae)
- Nudaurelia capensis omega virus (Omegatetravirus nudaureliae)
Structure
Viruses in Omegatetravirus are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear and bipartite, around 2.5kb in length.[1]
