Why is biological control considered a sustainable pest management strategy?

• A. It uses synthetic chemicals
• B. It relies on natural predators or parasites
• C. It requires high doses of herbicides
• D. It is not affected by environmental changes

Answer: (B)

Biological control is considered a sustainable pest management strategy primarily because it relies on natural predators, parasites, or pathogens to manage pest populations. This approach utilizes the natural ecosystem's balance, allowing for a reduction in pest numbers without the need for synthetic chemicals or high doses of herbicides. By enhancing or introducing biological agents that target specific pests, the method promotes a healthier ecological environment and reduces reliance on chemical treatments, which can have negative environmental impacts. This strategy not only reduces the likelihood of developing pesticide resistance in pest populations but also helps maintain biodiversity within the ecosystem. Biological control methods are often more in harmony with the natural biological processes, supporting long-term agricultural productivity and sustainability. Thus, the reliance on natural predators or parasites makes biological control a valuable component of integrated pest management (IPM) strategies that aim for ecological balance.
