Now that's *funny*.

You would have to sit each individual down at the machine, and convince
each blood cell to go through that capillary to be inspected. That may take
some time.
Instead, let the mosquitoes kill themselves. There are a number of ways:
Baiting Mosquitoes with Knowledge and Proven Insecticides
At the Agricultural Research Service (ARS) Center for Medical,
Agricultural and Veterinary Entomology (CMAVE) in Gainesville, Fla.,
entomologist Sandra Allan is using toxic sugar-based baits to lure
and kill mosquitoes. Allan and her CMAVE cooperators are evaluating
insecticides and designing innovative technology to fight biting
insects and arthropods. ARS is USDA's principal intramural
scientific research agency.

survive/1206
How to Build a Mosquito Trap From an Old Tire
Mosquitoes love old tires. Scientists aren't exactly sure why.
There's something about the warm rubber - a chemical compound that
the mosquitoes can smell, perhaps - that attracts the insects to lay
their eggs in the tires' hollow insides. In backyard settings, old
tires are one of the biggest risk factors for mosquito breeding,
producing up to a third of all mosquitoes in the area.

old-tire-180958954/
Genetic Control of Mosquitoes
Genetics can potentially provide new, species-specific,
environmentally friendly methods for mosquito control. Genetic
control strategies aim either to suppress target populations or to
introduce a harm-reducing novel trait. Different approaches differ
considerably in their properties, especially between self-limiting
strategies, where the modification has limited persistence, and
self-sustaining strategies, which are intended to persist
indefinitely in the target population and may invade other
populations. Several methods with different molecular biology are
under development and the first field trials have been completed
successfully.

Personally, I like the Gene Drive approach. Self-propagating. Useful for
other pests, such as screwworm. These can attack anyone:

You may have something there. I too doubt that IR would affect a fly
much, but white LEDS emit a narrow UVA band which would be about in the
right range for a flys receptors. Its that UVA which pumps the
phosphors in the LED to produce the white light.

If the light-absorbing goop in the fly vision system doesn't absorb any
more at that wavelength than any other part of the fly idk how it
would've damaged it any more than any other part of the fly. Handheld
red laser pointer certainly wouldn't cause ionization. With enough power
I'm sure you could focus enough energy on the poor thing to damage it
with any wavelength but I'd guess the wings would go first.
Also OP is claiming he was able to hold a handheld laser pointer beam
directly on a fly's eye for 30 seconds from across a room. Ok...
Maybe flies have some more generally weakly light-sensitive receptors on
their extremities. Maybe getting hit with the laser pointer beam felt
like a soothing shower, that's why it stayed so long.

Combine a low power scanning LIDAR with a laser zapper. Sort of an
Anti Ballistic Mosquito Defense.

OPs aren't thinking big enough; OPs should get like a 1 watt UV laser
attached to an infrared tracking system and swiveling robotic arm that
vaporizes those suckers right out of the air. Pew pew!

Sadly all the "chicks" who once found laser pointers novel are likely in
their mid-60s by now. The younger ones are too busy with their phones to
look up
