The story

Scientists have discovered that malaria-carrying mosquitoes are deterred by the smell of certain animals, particularly chickens.

Working in Ethiopia, researchers found that the Anopheles arabiensis mosquito strongly preferred human to animal blood. And while it fed randomly on cattle, goats and sheep, it avoided chickens.

They feed on humans and other domestic animals, but not on chicken, because the mosquito antennae did not respond.

Person sleeping under untreated bed nets inside the house, the light trap attached to the chicken didn't catch the malaria mosquitoes, while the light trap in which human beings slept overnight collected quite a significant number of malarial mosquito.
