The release of which of the following into ponds and wells helps in controlling mosquitoes?

Options

A. Snail
B. Crab
C. Dogfish
D. Gambusia fish

Answer

D

Explanation

The Gambusia fish, also known as mosquitofish, feeds on the larvae of mosquitoes. So it helps in controlling their population. Mosquitofish were introduced directly into ecosystems in many parts of the world as a bio-control to lower mosquito populations which in turn negatively affected many other species in each distinct bioregion.
