What does biological control of insects primarily involve?

Biological control of insects primarily involves the use of natural predators and parasites to manage pest populations. This method leverages the natural ecosystem by introducing or enhancing the population of beneficial organisms that target specific pest species. For instance, ladybugs can be used to control aphid populations, while parasitic wasps can lay eggs in or on pest insects, eventually leading to their demise. This approach is sustainable and minimizes the reliance on synthetic chemicals, reducing the risk of negative environmental impacts. By fostering a balance within the ecosystem, biological control not only targets pests but also supports biodiversity and promotes a healthier agricultural environment.
