Chloriridovirus is a genus of viruses, in the family Iridoviridae.{{cite web|title=Iridoviridae|url=https://ictv.global/report/chapter/iridoviridae/iridoviridae|website=ICTV Online (10th) Report|language=en}} Diptera with aquatic larval stage, mainly mosquitoes, lepidoptera, and orthoptera insects serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: yellow-green iridescence beneath the epidermis (early mosquito larval stages are most susceptible to infection). Death rates are highest in the fourth instar.{{cite web|title=Viral Zone|url=http://viralzone.expasy.org/all_by_species/582.html|publisher=ExPASy|accessdate=15 June 2015}}{{cite book|last1=Willis|first1=Dawn B.|editor1-last=Gholamreza|editor1-first=Darai|title=Molecular Biology of Iridoviruses|date=1990|publisher=Springer Verlag|isbn=978-1-4612-8893-0|pages=1–12|chapter=Taxonomy of Iridoviruses}} Viruses within this genus have been found to infect mosquito larvae, in which they produce various iridescent colors.{{cite journal|last1=Becnel|first1=James J.|title=Current status of Deltabaculoviruses, Cypoviruses and Chloriridoviruses pathogenic for mosquitoes|journal=Virologica Sinica|date=16 January 2008|volume=22|issue=2|pages=117–127|doi=10.1007/s12250-007-0013-4}}

Structure
Viruses in the genus Chloriridovirus are enveloped, with icosahedral and polyhedral geometries, and T=189-217 symmetry. The diameter is around 180 nm. Genomes are linear, around 135kb in length. The genome codes for 126 proteins.

Life cycle
Viral replication is nucleo-cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the DNA strand displacement model. DNA-templated transcription is the method of transcription. Diptera with aquatic larval stage, mainly mosquitoes, lepidoptera, and orthoptera insects serve as the natural host.
