The natural enemies like parasitism, predation and other mechanisms for controlling the plant pests are referred as a biocontrol agent. They play an important role in controlling the plant pests like nematodes weeds, insects, and mites.As mentioned above, there are many pest control methods available to choose from, but they can be loosely grouped into six categories: Hygienic, Biological, Chemical, Physical, Fumigation, and Heat treatment.
Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. ... Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors.First, management occurs at the microbial level, typically in biological microcosms (leaf surfaces, fruit surfaces, etc.) (Andrews, 1992). Second, biological control agents include competitors as well as parasites.a method or test involving experiment on organisms — compare bioassay.An example of biological control is the release of parasitic wasps to control aphids. Aphids are a pest of plants and cause huge damage to plants as they remove nutrients from the plant. The parasitic wasp lays eggs in aphids, as shown in the movie.
