Baculoviruses helps in saving the environment from the pollution caused by chemical pesticides. It kills the harmful insects and arthropods. These viruses are pathogenic for certain insects. They are used in the Integrated pest management program (IPM) in which the harmful insects are destroyed while the beneficial ones are being conserved. The majority of the baculoviruses used as biopesticides belong to the genus Nucleopolyhedro viruses (NPV’s). They produce a potent neurotoxin while they release after being dissolved in the midgut of the insects thereby causing its death.
