MDARD Michigan Core Pesticide Applicator Practice Exam

What is the primary focus of biological control?

1. Use of chemicals to kill pests

2. Altering the pest's biological nature

3. Utilization of natural enemies for pest control

4. Implementation of mechanical devices to eliminate pests

The correct answer is: Utilization of natural enemies for pest control

The primary focus of biological control is to utilize natural enemies for pest control. This approach leverages the existing ecological interactions between organisms to manage pest populations. By introducing or enhancing the presence of predators, parasites, or pathogens that are naturally found in an ecosystem, biological control seeks to reduce pest numbers in a sustainable and environmentally friendly manner. This method contrasts sharply with other pest management strategies, such as chemical control, which relies on the use of synthetic or natural pesticides. Rather than directly killing pests with chemicals, biological control aims to create a balance in the ecosystem, making it less conducive for pest populations to thrive. As a result, it often promotes the health of non-target species and reduces the risk of pesticide resistance developing among pests. Utilizing natural control agents not only reduces the need for chemical applications but also contributes to biodiversity and fosters resilient agricultural systems. In this way, biological control is a vital component of integrated pest management and an increasingly preferred method in sustainable agriculture practices.
