There is a company working on it… https://en.m.wikipedia.org/wiki/Mosquito_laser
The current plan is a ‘fence’ which will detect, identify, and kill 50 mosquitos per second. It can be tuned to only kill female mosquitos of the malaria carrying species measuring reflectivity and wing beat frequency. They speculate it could cost $50 for a 30 meter fence.
Looks like the company is targeting citrus pests in order to get some cash moving, mosquitos will come later now. https://www.technologyreview.com/s/603721/insect-zapping-las...
