What factor can enhance the efficacy of biological control methods?

• A. Use of multiple pesticides
• B. Maintaining biodiversity and habitat diversity
• C. Growing only monocultures
• D. Applying chemicals in high doses

Answer: (B)

Maintaining biodiversity and habitat diversity is crucial for enhancing the efficacy of biological control methods. This approach fosters a balanced ecosystem where natural predators and parasites can thrive, helping to regulate pest populations effectively. High biodiversity provides various niches and resources, allowing beneficial organisms to flourish and, in turn, improve their ability to control pest species. These natural controls can reduce reliance on chemical interventions, making pest management strategies more sustainable and environmentally friendly. In contrast, the other choices do not support the effectiveness of biological control. The use of multiple pesticides can disrupt the natural balance of an ecosystem, potentially harming beneficial species. Growing only monocultures can lead to a lack of diversity and increase vulnerability to pests and diseases, while applying chemicals in high doses may eliminate both pests and their natural enemies, undermining the effectiveness of biological control methods.
