Baculoviridae is a family of viruses that are known to infect insects, primarily moths and butterflies. This group includes several species that are widely used in biotechnology, as they have been developed into vectors for gene therapy and protein expression. However, there are also several synonyms for the term Baculoviridae, including Baculovirus, Baculoviral vector, and Baculoviral expression system. These terms are used to describe the different applications of the virus in the fields of molecular biology and genetic engineering. Regardless of the term used, the Baculoviridae are considered to be highly versatile and effective tools for the production of recombinant proteins.
