What type of pest control method includes the use of natural enemies like predators and parasites?

The method that involves the use of natural enemies such as predators and parasites is known as biological control. This approach leverages the natural relationships that exist within ecosystems where certain organisms can help manage pest populations by preying on them or parasitizing them. For instance, ladybugs are effective at controlling aphid populations, while certain wasps lay their eggs inside pest insects, leading to the latter's decline.

Biological control is environmentally friendly and aims to establish a balance between pests and their natural controls, reducing the reliance on synthetic chemicals. This strategy not only minimizes the ecological footprint of pest management practices but also promotes biodiversity. By recognizing and utilizing these natural relationships, biological control contributes to sustainable agriculture and pest management practices.
