Biological Control Of Pests

Biological Control of pests requires active human role. Here reduction of pest population is made effective by natural enemies. These natural enemies of insect pests are called biological control agents. They include predators, parasitoids and pathogens.

Predators are such species which consume a large number of preys during their life span that are lady beetles and lace wings. Parasitoids finally kill the host. Their immature stage develops on or within that single host and most have a very narrow host range for example wasps and flies. Pathogens are organisms which cause diseases for example bacteria, fungi, viruses. They also kill the host.
