Which pest management strategy relies on beneficial organisms?

• A. Cultural practices
• B. Biological control
• C. Mechanical control
• D. Chemical control

Answer: (B)

The strategy that relies on beneficial organisms is biological control. This method utilizes natural predators, parasites, or pathogens to manage pest populations. For example, introducing ladybugs can help control aphid populations, as these insects feed on aphids and reduce their numbers. This approach aims to enhance the role of natural ecosystems in managing pest populations, minimizing the need for synthetic pesticides and promoting a more sustainable and environmentally friendly method of pest management.

Biological control is particularly valuable in maintaining ecological balance, as it leverages the natural predator-prey relationships found in the environment. This helps to create a healthier ecosystem and can lead to long-term pest management solutions. By relying on living organisms, biological control can also reduce the risks and side effects associated with chemical pest control methods.
