densovoviruses

Densovoviruses are a genus of viruses in the family Parvoviridae. They are known to infect arthropods, particularly insects. These viruses are characterized by their single-stranded DNA genome. The name "densovirus" is derived from the French "densonucléose," referring to dense nuclear inclusions formed in infected cells. The genome is typically linear and about 4 to 6 kilobases in length, encoding for a small number of proteins, including structural capsid proteins and non-structural replication proteins.

Replication of densovoviruses occurs exclusively in the nucleus of host cells. They enter the cell and the viral DNA is transported to the nucleus where it is replicated. The viral genes are transcribed and translated, leading to the production of new virions. Infected insects often exhibit symptoms such as reduced feeding, lethargy, and a change in body color. In some cases, densovoviruses can cause significant mortality in insect populations, making them of interest for biological control applications. Several species of densovoviruses have been identified, each with a specific range of insect hosts. Research continues to explore their biological characteristics, host interactions, and potential uses in pest management.
