What does biological control entail?

Biological control refers to the method of managing pest populations by utilizing the natural predators, parasites, or pathogens that target specific pests. This approach aims to maintain pest species at manageable levels through ecological means rather than through chemical interventions. The intentional release of natural enemies, such as ladybugs, lacewings, or certain parasitic wasps, effectively establishes a balance between pest species and their predators, reducing the need for synthetic pesticides and minimizing environmental impacts.

The other options, while related to agricultural practices, do not align with the principles of biological control. The use of chemical pesticides represents a conventional method of pest management that relies on synthetic substances rather than natural organisms. The introduction of genetically modified organisms (GMOs) primarily focuses on enhancing crop traits, which may not directly address pest control. Finally, applying fertilizers to boost plant growth is unrelated to pest management strategies and instead concentrates on improving plant health and yield. Thus, the correct understanding of biological control specifically highlights the role of natural enemies in regulating pest populations.
