There are several types of biological control including the direct introduction of parasites, pathogens and predators to target mosquitoes. Effective biocontrol agents include predatory fish that feed on mosquito larvae such as mosquitofish (Gambusia affinis) and some cyprinids (carps and minnows) and killifish. Tilapia also consume mosquito larvae.[2] Direct introduction of tilapia and mosquitofish into ecosystems around the world have had disastrous consequences.[3] However, utilizing a controlled system via aquaponics provides the mosquito control without the adverse effects to the ecosystem.
