Campoletovirus

Campoletovirus is a genus of viruses in the order Picornavirales and the family Iflaviridae. These viruses infect insects, particularly arthropods. The name "Campoletovirus" is derived from the Greek word "campo" meaning field and "leto" meaning hidden, referring to their often unnoticed presence in agricultural fields.

Campoletovirus particles are non-enveloped and have an icosahedral capsid. Their genome consists of a single-stranded positive-sense RNA molecule. Replication occurs within the cytoplasm of the host insect cells. The life cycle typically involves the virus entering the host, replicating its genetic material and proteins, and then assembling new viral particles which are released to infect other cells.

Species within the Campoletovirus genus are known to infect various insect species, including those that are agriculturally important pests. The specific hosts and the diseases they cause can vary. Some Campoletoviruses have been associated with reduced fitness and increased mortality in their insect hosts. Research into Campoletoviruses is ongoing, with a focus on understanding their molecular biology, host-virus interactions, and potential applications in biological control of insect pests. Their study contributes to the broader understanding of insect virology and the diversity of RNA viruses.
