Ethiopian and Swedish scientists discovered that malarial mosquitoes tend to avoid chickens and other birds. The scientists concluded that as mosquitoes use their sense of smell to locate an animal they can bite, there must be something in a chicken's odour that puts the insects off. Compounds from the smell of the chicken can be extracted and could work as a repellent. Field trials for this stage of the research are now "in the pipeline", the BBC was told. [Source: BBC News]
