What role do beneficial insects play in pest management?

Beneficial insects play a crucial role in pest management by helping to control pest populations naturally. This occurs through predation, parasitism, or competition with harmful pests. For instance, certain insects, like ladybugs and lacewings, feed on aphids and other common pests, thereby reducing their numbers without the need for synthetic pesticides. Additionally, some beneficial insects lay their eggs in or on pest insects, leading to the pest's death and helping to keep pest populations in check. Utilizing beneficial insects is an environmentally friendly method of managing pests, promoting a more balanced ecosystem and reducing reliance on chemical interventions.
