Baculovirus: Baculovirus is a family of viruses. Arthropods, lepidoptera, hymenoptera, diptera, and decapoda serve as natural hosts. The baculoviruses used as biological control agents are in the genus Nucleopolyhedrovirus, so "baculovirus" or "virus" will hereafter refer to nucleopolyhedroviruses. These viruses have no negative impacts on plants, mammals, birds, fish, or even on non-target insects. Baculovirus expression in insect cells represents a robust method for producing recombinant glycoproteins or membrane proteins. It produced proteins are currently under study as therapeutic cancer vaccines. It is considered a safe option for use in research applications.
