    Gambusia  feeds on the mosquito larvae thus acts as biological control of the mosquito population, Hence, Gambusia is introduced in stagnant water where mosquitoes lay eggs and larvae are hatched.
    Gambusia is a natural enemy of larva and pupa of mosquitoes as it feeds upon them and thus helps control the breeding of mosquitoes. So, it is introduced into drains and ponds.
