What is the common method used to control mosquito populations in wetlands?

The common method used to control mosquito populations in wetlands is biological control. This approach utilizes natural predators to manage mosquito numbers, aiming to establish a balanced ecosystem where these predators can thrive and effectively reduce mosquito populations. Organisms such as fish, amphibians, and certain insect species feed on mosquito larvae, which helps limit their growth and impact.

Biological control is often favored in wetland areas because it minimizes chemical use, which can have detrimental effects on the environment and non-target species. By maintaining a natural predator-prey balance, this method is not only effective but also sustainable in the long term, contributing to the health of the wetland ecosystem.

Other methods, such as chemical control, might involve the application of pesticides which can pose risks to both the environment and human health. Physical removal methods can be impractical in large or sensitive wetland areas, and habitat modification, while it can help reduce breeding sites, may not always be feasible. Therefore, biological control stands out as a preferred method in managing mosquito populations in these ecosystems.
