Moire bednetting repels mosquitos
Some flying insects avoid stripes, that might include mosquitos. Create a moire effect at mosquito nets to make them a few % more effective | |
National Geographic [link] says zebra stripes repel flies, with narrower stripes being more effective [link]. It is possible that when tested, this also works on mosquitos. Creating an optimized moire pattern (true layers or printed) at a mosquito net (test hypno concentric circles etc.) could make
mosquito nets even more effective, reducing malaria further.
The National Geographic also says the insects are responding to polarized light, so the printed pattern could actually just be a polarization coating, possibly invisible to humans.

// stripes repel flies // |

Not useful - because it doesn't kill them. What's the good of
scaring them away ? |
|
| |
Kill them. Kill them all. Preferably, cripple them so they die very
slowly; but as long as they do die, that's fine. |
|
| |
Interesting though. (+)
I wonder if the same patterns could be generated using heat waves to create the patterns out of thin air without the net. |
|
| |
When I was younger I spent a lot of time trying to get a net
into my bed. |

<obligatory misreading of title> I misread the title
as "Moire bedwetting repels mosquitos" and was
intrigued as to how this would work. </obligatory

Is this when you cross the streams? |
|
| |
I think someone should test the effect of LEDs, of various wavelengths, strobing at different rates, on mosquitoes. There's got to be some wavelength/pulse-rate combination that gives them epileptic fits. |
|
| |
How would you know when they had one? Would they start
to fly in a straight line? |
|
| |
They shouldn't be able to fly at all. |
|

// gives them epileptic fits. // |
|
| |
Since mosquitoes only have a few thousand neurons - little more than ganglia, preprogrammed for simple, instinctive responses - it's unlikely that it's technically possible for them to experience epileptic fits. |
|
| |
The answer would be to test the stimuli on a creature with a similar paucity of cerebral material, capable of a pathetically meagre repertoire of basic reflexes. We suggest that socialists* would be a good starting point, then moving up to more complex organisms, such as anemones. |

*Although obviously not Labour MP's**. There are things that grow on damp bread that are smarter than Labour MP's. |
|
| |
**And certainly not members of the shadow cabinet. There are viruses which barely qualify as "life" that are individually much smarter than the entire shadow cabinet. |
|
| |
//it's unlikely that it's technically possible for them to experience epileptic fits. // |
|
| |
Au contraire. In the human brain, there are gazillions of pathways and interconnections, so it's astonishing that it can get into any kind of uncontrolled oscillation. |
|
| |
In a mosquito brain, there are indeed probably only a few thousand neurons, of which those handling vision will be a large proportion. So, there's a good chance that some frequency of light pulses will set up some unpleasant kind of resonance. |

The troubling thing about [8th]'s first anno is that, apart from the
1st-line quote, he could easily have applied it to any idea in the
'bakery. |
|
| |
This bespeaks a worryingly low information content. |
|
| |
<stats corner> The second word in the last sentence
of [pertinax]'s annotation, starting "be...", has
only been used six times on the Halfbakery, four
times by [8th] and twice by [pertinax] </stats

[hip], you need to get out more and meet people your own age. |

Verily; I relish idiosyncratic words and herald their
occurence |
