Hymenoptera Hymenoptera is a large order (biology), order of insects, comprising the sawfly, sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are Par ...

serve as natural hosts. There are two species in this genus.

Taxonomy

The following species are assigned to the genus: *'' Neodiprion lecontei nucleopolyhedrovirus'' *'' Neodiprion sertifer nucleopolyhedrovirus''

Structure

Viruses in ''Gammabaculovirus'' are enveloped. Genomes are circular, around 82-86kb in length. The genome codes for 90 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. Hymenoptera serve as the natural host. Transmission routes are fecal-oral.
