  What for nucleo polyhedro viruses are being used now a-days?

Answer:

                  Several methods of biological control are being used in the pest management to keep the pollution-free environment and yield clean, non-toxic and good quality products for human consumption. Baculoviruses are a group of viruses used as biological control agents that occur naturally and are specific to some insects. Most of the baculo viruses belong to the genus Nucleopolyhedro virus. These viruses are excellent candidates for species-specific, narrow spectrum insecticidal applications. They have been shown to have no negative impacts on plants, mammals, birds fish or even on non-target insects. This is especially desirable when beneficial insects are being conserved to aid in an overall Integrated Pest Management (IPM) Programme or when an ecologically sensitive area is being treated.
