Which mosquito control technique uses natural predators?

The correct choice is biological control, as this technique relies on the use of natural predators to manage mosquito populations. This method can involve introducing or encouraging organisms that feed on mosquito larvae or adult mosquitoes, such as certain fish, dragonflies, or specific types of insects. By utilizing these natural enemies, biological control effectively reduces mosquito populations while minimizing the impact on the environment, as it often requires fewer chemicals and harmful substances.

Biological control is particularly effective because it promotes a balanced ecosystem, where natural predation can help maintain mosquito levels at a manageable rate without the need for continuous human intervention. This approach aligns with environmentally friendly pest management strategies that prioritize sustainability.

Other options, such as cultural practices, mechanical control, and chemical control, represent different techniques that do not focus on leveraging natural predators. Cultural practices involve modifying the environment to make it less conducive to mosquito breeding, mechanical control refers to physical removal methods like trapping or elimination of breeding sites, and chemical control utilizes insecticides to kill mosquitoes, which can have negative environmental impacts and affect non-target species.
