A virus that infects lepidopteran insects (e.g., cotton bollworm or gypsy moth larva). Baculoviruses can be modified via genetic engineering to insert new genes into the larva, causing those larva to then produce proteins desired by man (e.g., pharmaceuticals).
A double-stranded DNA virus that infects insects. It has been used experimentally in recombinant DNA technology, e.g., in manufacturing vaccines.
