Context: With the change in season and rise in temperature, culex or common house mosquitoes have made a reappearance across the capital.

What are Culex mosquitoes and why is there a need to worry?

  • Warmer temperatures are the main reason for the appearance of these mosquitoes.
  • Their presence is especially felt more in areas around floodplains in East and South Delhi as it is an ideal condition of breeding.
  • Culex mosquitoes are known carriers of some serious diseases. They can fly up to a distance of 1-1.5 km.

  • Culex mosquitoes are known carriers of Japanese encephalitis, a potentially life-threatening but rare viral disease that causes “acute inflammation” of the brain.
  • They breed in dirty, stagnant water.
