Dicistroviridae
''Dicistroviridae'' is a family of viruses in the order ''Picornavirales''. Invertebrates, including aphids, leafhoppers, flies, bees, ants, and silkworms, serve as natural hosts. There are 16 species in this family, assigned to three genera. Diseases associated with this family include: DCV: increased reproductive potential. extremely pathogenic when injected with high associated mortality. CrPV: paralysis and death. Taxonomy Although many dicistroviruses were initially placed in the ''Picornaviridae'', they have since been reclassified into their own family. The name (Dicistro) is derived from the characteristic dicistronic arrangement of the genome. This family is a member of the Order ''Picornavirales'' (along with the families '' Iflaviridae'', ''Picornaviridae'', and ''Secoviridae'' and '' Marnaviridae''). Within this order, the gene order is the gene order of the nonstructural proteins Hel(helicase)-Pro(protease)-RdRp(polymerase). The ''Dicistroviridae'' can be disting ...

Triatoma Virus
Triatoma virus (TrV) is a virus belonging to the insect virus family ''Dicistroviridae.'' Within this family, there are currently 3 genera and 15 species of virus. Triatoma virus belongs to the genus ''Triatovirus''. It is non-enveloped and its genetic material is Positive-sense single-stranded RNA virus, positive-sense, single-stranded RNA. The natural hosts of triatoma virus are invertebrates. TrV is a known pathogen to ''Triatoma infestans'', the major vector of Chagas disease in Argentina which makes triatoma virus a major candidate for biological vector control as opposed to chemical insecticides. Triatoma virus was first discovered in 1984 when a survey of pathogens of triatomes was conducted in the hopes of finding potential biological control methods for ''T. infestans''. Viral classification TrV is a positive-sense, single-stranded RNA virus. It belongs to virus Group IV. Virus groups are based on the Baltimore classification system.
