AMERICAN scientists are making a ray gun to kill mosquitoes. Using technology developed under the Star Wars anti-missile programme, the zapper is being built in Seattle where astrophysicists have created a laser that locks onto airborne insects.

Scientists have speculated for years that lasers might be used against mosquitoes, which kill nearly 1m people a year through malaria.

The laser – dubbed a weapon of mosquito destruction (WMD) – has been designed with the help of Lowell Wood, one of the astrophysicists who worked on the original Star Wars plan to shield America from nuclear attack.

“We like to think back then we made some contribution to the ending of the cold war,” Dr Jordin Kare, another astrophysicist, told The Wall Street Journal. “Now we’re just trying to make a dent in a war that’s claimed a lot more lives.” The WMD laser works by detecting the audio frequency created by the beating of mosquito wings. A computer triggers the laser beam, the mosquito’s wings are burnt off and its smoking carcass falls to the ground. The research is backed by Bill Gates, the Microsoft billionaire.

It is speculated that lasers could shield villages or be fired at swarming insects from patrolling drone aircraft. “You could kill billions of mosquitoes a night,” said one expert.
