How can natural predators help control mosquito larvae?

• A. They reduce the number of mosquitoes by mating
• B. Fish and certain insects feed on mosquito larvae
• C. They attract adult mosquitoes away from laying eggs
• D. They cause larval growth to accelerate

Answer: (B)

Natural predators play a significant role in controlling mosquito populations by directly feeding on mosquito larvae. Fish, such as minnows, and certain insects, like dragonfly nymphs, are known for their predatory habits concerning mosquito larvae. When these predators are present in bodies of water, they can significantly decrease the number of larvae that develop into adult mosquitoes. This biological control method is effective because it taps into the natural ecosystem, promoting a balance that minimizes mosquito populations without reliance on chemical insecticides. By employing natural predators, communities can achieve a more sustainable and environmentally-friendly approach to mosquito management.
