What is an example of an integrated pest management technique?

An example of an integrated pest management (IPM) technique is the combination of biological controls with trapping. Integrated pest management emphasizes a holistic approach to controlling pest populations by integrating multiple strategies that are environmentally sound and economically viable.

By utilizing biological controls—such as introducing natural predators or parasites of the pest species—alongside trapping methods to physically capture or monitor pest populations, this technique helps manage pests in a sustainable way. It reduces reliance on chemical pesticides and promotes the health of the ecosystem, maintaining a balance between pest control and ecological integrity.

The other options do not align with the principles of IPM. Using only chemical pesticides ignores the benefits of alternative control methods, while ignoring prior pest infestations overlooks valuable data that could inform effective management strategies. Applying pesticides indiscriminately can lead to increased resistance in pest populations, harm non-target species, and disrupt ecological balance, which directly contradicts the IPM philosophy of minimal environmental impact.
