What is a common characteristic of biological pest control?

Biological pest control is characterized by the introduction of natural predators or parasites to manage pest populations. This method leverages the existing balance in ecosystems, where certain organisms can keep pest populations in check without the need for synthetic chemicals or harmful interventions. By utilizing these natural enemies, biological control can be an environmentally friendly and sustainable approach to pest management.

This method is often favored for its minimal environmental impact and its ability to establish a more long-lasting ecological balance. Unlike chemical methods that may offer quick but temporary solutions, biological control seeks to create an ongoing relationship between pests and their natural enemies. Thus, the answer revolves around the core principle of using ecological relationships to achieve pest control while promoting sustainability in agricultural practices.
