What pest management strategy incorporates natural predators?

Biological control is the pest management strategy that incorporates natural predators to keep pest populations in check. This method involves using other organisms, such as insects, birds, or microorganisms, to naturally reduce pest populations. For example, ladybugs are often released in gardens to control aphid populations, which helps to maintain a balance in the ecosystem without relying on synthetic pesticides.

This approach is beneficial because it often leads to more sustainable pest management practices. It enhances biodiversity and can reduce the likelihood of pest resistance that often occurs with chemical controls. Biological control is a key practice in integrated pest management, aiming to create a healthier environment while effectively managing pests.

In contrast, the other strategies mentioned focus on different tactics such as using synthetic chemicals, altering agricultural practices, or employing physical barriers, none of which leverage the use of natural predators in the same way biological control does.
