Some yellow lights are supposed to repel
mosquitoes etc.

Is there a color that will repel or dissuade
insect pests? I'm thinking of painting stakes or
trellises any suitable color.

I don't think that is right. The way I think it goes is that many insects'
eyesight works best in the blue and ultrviolet region of the spectrum and so
yellow light is invisible (or less visible) so they are not attracted at
night to a yellow light as much as a white one. Nothing about repelling
them.

I think this is mission impossible.

It's not that yellow repels mosquitoes, it just doesn't attract them,
and other insect, like white lights do.

With hummingbird feeders - word is you should avoid yellow because yellow
jackets are attracted to it (and find the yummy syrup). So red is
preferred there.

Of course, maybe a yellow fence would be good, they're not going to find
much syrup there!

Insect visual systems vary a lot, depending on what it eats, when it
breeds,... If you have a _specific_ insect that is problematic for you,
find out more about that. I don't think you'll find a one-size-repels-
all.

Thanks. I live in town and I want to grow a
tomato plant in a pot with a special wooden stake
I've invented... (in the corner)

The bugs are quite voracious and have damaged a
cumquat tree and my Tahitian lime tree. Only
pelagoniums and cycads seem to survive. I
thought to paint the stake some suitable colour.

I suspect it is not the same bugs damaging your tomato and citrus. You need
to find out what specifically is doing it so you can beat it. There are
many methods (spraying, trapping, exclusion, providing predators etc) but to
work out the best in your case you need to know the culprit. Colour coding
won't work.
