Entomopathogenic viruses are specialized viruses that infect and kill insects. They belong to various families, including Baculoviridae and Nucleopolyhedrovirus. These viruses can be used in biological control to manage pest populations in agriculture, reducing the need for chemical pesticides. These viruses typically enter the insect host through ingestion or direct contact. Once inside, they replicate and cause the host to exhibit symptoms such as paralysis or death. This natural method of pest control is considered environmentally friendly and can help maintain ecological balance while protecting crops from harmful insects.
