What light insects are not attracted to?

Community and Forum → Insects biology and faunistics → What light insects are not attracted to?

Good time of day!
The problem is the following: usually entomological forums discuss how to attract insects in order to collect them more efficiently; here the task is completely the opposite: you need to illuminate the object, but not attract insects, and if possible, even scare confused.gifthem away ...
Why this question arose, the fact is that in the Crimea it is planned to install a complex of powerful wind turbines and not one, but several. At the same time, it is known that there are certain environmental restrictions for the installation, first of all, it is the safety of birds and bats, since there are statistics confirming the facts of death under turbines, especially the latter umnik.gif. So, wind turbines should be illuminated at night with powerful spotlights, the light of which attracts insects, and therefore bats, which in turn will increase the risk of their death....
Thanks in advance for your thoughts on this beer.gif

In my opinion, the red and yellow parts of the spectrum are the least attractive to insects. Don't forget that the lower the UV, the better.

What about the cold part of the cheese, say green?

Huge red windmills are cool. Yes, even if you accidentally catch some mouse, it will still be invisible. A joke, a joke.

The most correct thing is not to light it in any way (except for the red signal lamps at the top). These windmills spin at a low speed and emit mostly infrasound noise. Birds also die when they collide with tall buildings, and any light can be attractive to them. Bats, on the other hand, should not encounter stationary and/or low-speed obstacles at all due to echolocation. You can, of course, ultrasound against the years.Try the mice, but I'm afraid it will only get worse. So, the problem should be ignored, in order to avoid tongue.gif

Somewhere at the level of the subcortex, I remember that somewhere at airfields they put specially orange filters on the searchlights.

In fact, there is a problem (in the sense of mice), at least the Americans, Germans and British found out for sure, we have to use their experience, because we have not yet installed such units of more than 2 MW, and if they do, they are unlikely to go and count downed mice eek.gif
And the Americans have already tried to repel ultrasound tongue.gif

in fact, about the mice is doubtful somehow... that they are completely stupid or something? wink.gif a wire 0.08 mm in diameter is distinguished, but the blades of a huge windmill are not? And then what will the branches of swaying trees do to them? how do they catch flying insects at all?
and why light the windmill itself? There's a red searchlight up, so you can see everything from the helicopter...

we know such documents... impatto ambientale... there are a lot of words and no clear data, but you can accept anything in the resolution - it's not a peer-reviewed article...

Why light up wind farms with powerful spotlights? There are a lot of wind farms in Austria, Slovakia and Hungary. Entire forests of windmills stretch for tens of kilometers and not a single one of them is highlighted. On the contrary, you should remove the light so as not to attract insects and other animals
