What is an example of biological pest control?

Biological pest control involves using living organisms to manage pest populations, and introducing beneficial insects is a prime example of this method. Beneficial insects, such as ladybugs and lacewings, are natural predators of many pests that can harm crops or be destructive in other environments. By promoting or introducing these beneficial species into an ecosystem, you can help keep harmful pest populations in check without relying on chemical pesticides. This approach enhances the natural balance within the ecosystem, leading to healthier plants and reduced pest issues over time.

The other methods listed, while they may help manage pests, do not fall under biological pest control. Applying pesticides involves the use of chemicals to kill pests directly, while using non-toxic traps is a physical method of controlling pest numbers rather than leveraging natural predators. Increasing hive temperature could potentially influence bee behavior but does not directly relate to controlling pests in terms of biological methods.
