Structure

Viruses in ''Betabaculovirus'' are enveloped. Genomes are circular, around 80-180kb in length. The genome codes for 100 to 180 proteins.

Life cycle

Viral replication is nuclear. Entry into the host cell is achieved by attachment of the viral glycoproteins to host receptors, which mediates endocytosis. Replication follows the dsDNA bidirectional replication model. Dna templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear pore export, and existing in occlusion bodies after cell death and remaining infectious until finding another host. Arthropods serve as the natural host. Transmission routes are fecal-oral.
