Deltabaculovirus is a genus of viruses, in the family Baculoviridae. Mosquito larvae serve as natural hosts. There is only one species in this genus: Culex nigripalpus nucleopolyhedrovirus (Deltabaculovirus cunigripalpi).{{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=Viral Zone|url=http://viralzone.expasy.org/all_by_species/539.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}}{{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}}

Structure

Viruses in Deltabaculovirus 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.

Mosquito larvae serve as the natural host. Transmission routes are fecal-oral.
