Granulovirus is a type of virus that specifically infects insects, particularly caterpillars. It belongs to the family of Baculoviridae and is known for its role in biological pest control. Granuloviruses are characterized by their ability to form granules, which are small, protein-coated particles that contain the viral DNA. These viruses are often used in agriculture to manage pest populations without harming beneficial insects or the environment. When a caterpillar ingests the virus, it can lead to disease and death, helping to reduce crop damage caused by these pests. Granulovirus is considered a safer alternative to chemical pesticides.
