Why are baculoviruses used as biological control agents?

उत्तर १
Baculoviruses are good biocontrol agents because they target specific insect pests without harming plants, animals, or beneficial insects, making them safe and effective for integrated pest management programmes. They are species-specific and environmentally friendly.
उत्तर २
- For example, the well-known baculovirus Nuclear Polyhedrosis Virus (NPV) is employed to manage pests such as Helicoverpa armigera, or cotton bollworm.
- When consumed by target insect pests, baculoviruses proliferate inside their cells, eat down tissue, and eventually kill the host.
- Only harm some insect pests while sparing beneficial insects.
- Environmentally acceptable substitute for chemical insecticides.
