The release of which one of the following into ponds and wells helps in controlling the mosquitoes?
- Crab
- Dogfish
- Gambusia fish
- Snail
Explanation
Option (c) is correct
- Gambusia, commonly known as the mosquitofish, is released into ponds and wells because it feeds on mosquito larvae and helps control mosquito populations biologically. A single adult Gambusia can consume hundreds of larvae in a single day, effectively breaking the mosquito life cycle before they can fly and spread diseases like Malaria, Dengue, or Zika.
