Scientists have known that when mosquitoes go searching for a breeding spot, they stay away from places where backswimmers thrive — because they sense the insect’s chemical signature. Researchers from the University of Haifa, with a team of other academic researchers, believe they have identified (and reproduced) the chemical compounds released by that mosquito predator.
