What is the primary method of biological control used for mosquito populations?

Introducing predators is the primary method of biological control used for managing mosquito populations. This approach focuses on utilizing natural enemies of mosquitoes, such as certain species of fish (like guppies), amphibians, or other insects that feed on mosquito larvae. By introducing these predators into habitats where mosquitoes breed, it helps to naturally reduce the population of these pests without resorting to chemical methods.

Predator introduction is a sustainable and eco-friendly strategy that works to restore a balance in the ecosystem. It leverages natural interactions between species, promoting ongoing control of mosquito populations over time.

In comparison, while larviciding involves the use of chemicals to target and eliminate mosquito larvae, it is not considered biological control. Environmental management focuses on altering habitats to minimize breeding sites, and trapping adults is more about population management than biological control. Each of these methods has its usefulness but does not operate within the same framework as introducing predators.
