Nudiviridae is a family of viruses that primarily infect insects, particularly those in the order Lepidoptera, which includes butterflies and moths. These viruses are characterized by their large, double-stranded DNA genomes and are known to cause diseases in their hosts, leading to significant mortality in affected populations. The life cycle of Nudiviridae involves the virus entering the host's cells, where it replicates and eventually causes cell death. This can result in symptoms such as reduced growth and abnormal behavior in infected insects. Research on Nudiviridae contributes to understanding insect pathology and potential applications in biological control.
