Question

Name anyone larvivorous fish which is a natural predator of mosquito larvae.

Answer 1

Hint Mosquito-borne infections are still a big issue in nearly every tropical and subtropical country. They are responsible for the spread of infections that cause some of the most deadly and severe diseases.

Complete step by step answer:
The consequences of insecticides used to control human disease vectors are becoming more well-known. Manipulation or introduction of an auto-reproducing predator into the environment may provide pest populations with long-term biological control.
The self-replicating capability, preference for the target pest population in the presence of substitute natural prey, adaptability to the new environment, and overall interaction with indigenous creatures should all be considered when choosing a biological agent
Fish that feed on mosquito larvae are known as larvivorous fish. Larvivorous fish, according to Job15, must be small, hardy, and able to move about readily in shallow waters among dense weeds, where mosquitoes find suitable nesting grounds.
They must be drought-resistant and able to thrive in both deep and shallow waters, as well as in drinking water tanks and pools without contaminating the water.
They must be able to survive severe handling as well as long-distance shipping. Larvivorous fish must be prolific breeders with a shorter life cycle than other fish. They must be able to mate freely and successfully in a limited environment.
Gambusia is an opportunistic predator with a diverse diet that includes algae, zooplankton, aquatic insects, fish eggs and young, and amphibian eggs and young.

So, Gambusia is used as a natural predator of mosquito larvae.

Note: The use of larvivorous fish has a number of drawbacks. When Gambusia is stocked in waterways outside of its native area, it frequently has major ecological consequences. Furthermore, discovering and treating all anopheline mosquito larval homes within a given area can be difficult, and some larval habitats may be inappropriate for treatment.
