Final answer:
A pest-control program is a management strategy within Integrated Pest Management and may include using organisms to control pests, providing an eco-friendly and cost-effective alternative to chemical pesticides but with its own potential risks.
Step-by-step explanation:
A pest-control program is an example of an approach to manage and control pest populations that cause damage to crops, spread diseases, or compete with humans for food. Integrated Pest Management (IPM) is a sustainable approach, combining various strategies to restore the natural pest-predator balance within agricultural ecosystems. Biological control, one of the components of IPM, involves using organisms (e.g., predators, parasites, or pathogens) to control pest species. This method has seen some major successes, such as the use of South American weevils to control water hyacinth, and provides a low-cost, environment-friendly alternative to chemical pesticides, which can be expensive and harmful to non-target species and human health. However, biological control can have its own risks, such as the potential for introduced species to attack non-target species or cause extinctions.
