Mosquito flight and laser knockdown

How can a laser shoot down mosquitoes?

In order to use lasers in the fight against Zika and malaria, it's important to understand the biology of mosquito breeding and flight. 

High speed cameras need to be used to detect insects and identify mosquitoes. 
Here's an example of slow motion capture of a mosquito in flight captured by Intellectual ventures.

Mosquitoes beat their wings 250-1000 times a second, so this footage is amazingly slowed down.
 Astonishingly, this method claims to be able to distinguish male and female mosquitoes.
As you can imagine, the differences are subtle when the insect is in flight. Apparently female mosquitoes choose a mate based on the frequency of their wing beat.
Here's a video of the mosquito-killing laser in action:
