Gammabaculovirus is a genus of viruses, in the family Baculoviridae. Hymenoptera serve as natural hosts. There are three species in this genus.{{cite journal |last1=Harrison |first1=RL |last2=Herniou |first2=EA |last3=Jehle |first3=JA |last4=Theilmann |first4=DA |last5=Burand |first5=JP |last6=Becnel |first6=JJ |last7=Krell |first7=PJ |last8=van Oers |first8=MM |last9=Mowery |first9=JD |last10=Bauchan |first10=GR |last11=Ictv Report |first11=Consortium |title=ICTV Virus Taxonomy Profile: Baculoviridae. |journal=The Journal of General Virology |date=September 2018 |volume=99 |issue=9 |pages=1185–1186 |doi=10.1099/jgv.0.001107 |pmid=29947603|doi-access=free }}{{cite web |title=ICTV Report Baculoviridae |url=http://www.ictv.global/report/baculoviridae}}{{cite web|title=Viral Zone|url=http://viralzone.expasy.org/all_by_species/540.html|publisher=ExPASy|accessdate=15 June 2015}}{{cite web|title=Virus Taxonomy: 2024 Release|url=https://ictv.global/taxonomy|publisher=International Committee on Taxonomy of Viruses|access-date=28 March 2025}}
Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:{{cite web|title=Species List: Baculoviridae|url=https://ictv.global/report/chapter/baculoviridae/taxonomy/baculoviridae|publisher=International Committee on Taxonomy of Viruses|access-date=28 March 2025}}
- Gammabaculovirus neabietis, Neodiprion abietis nucleopolyhedrovirus
- Gammabaculovirus nelecontei, Neodiprion lecontei nucleopolyhedrovirus
- Gammabaculovirus nesertiferis, 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.
